FIRING ORDER THANK YOU FOR BUILDING TRULY AWESOME 4X4S!

his month’s issue of Four Wheeler is jam packed with a mind-blowing collection of 4x4 features. Feature 4x4s have been a popular staple of Four Wheeler for decades and being able to publish them is one of the best parts of my job. It’s thrilling to help show off a fellow wheeler’s rig and detail the story behind the machine. The first feature I photographed for a magazine was in the spring of 1989. The 4-Wheel & Off-Road Jamboree was in Pecatonica, Illinois, at the Winnebago County Fairgrounds and I helped coordinate the use of some family farmland so Off-Road and 4-Wheel & Off-Road magazines could photograph 4x4s from the Jamboree. I was a wheeler, reader of the off-road books, amateur photographer, and a wannabe off-road magazine staffer, so I spent as much time as possible watching the magazine staffers work. I studied things like their technique and how they positioned vehicles. I also talked with the vehicles’ owners and hung on every word as they told the backstory on their rigs. The duo of Stuart Bourdon and Brent Ross from 4-Wheel & Off-Road were photographing feature 4x4s in the pasture behind our house while Bruce Smith and Steve Reyes were at work on nearby property photographing rigs for Off-Road. I watched a steady stream of incredible 4x4s come and go for a couple of days before Bruce Smith asked if I wanted to photograph one of the feature rigs for Off-Road. I recall it was a built Suzuki Samurai. Little did I know at the time, but that Samurai would be the first of hundreds of feature 4x4s I would photograph over the next few decades. During the past 33 years of photographing feature 4x4s there have been many trends.

When I first started out in the late ’80s and early ’90s it was all about tall suspension height, bolting as many shocks as possible at each corner, and neon. Through the mid- to late-’90s I recall a mix of high-end show truck builds and more than a few 4x4s that qualified as quasi monster trucks. By the late ’90s, rockcrawling was coming on strong and I was photographing rockcrawlers and tube buggies. Soon, the highend show trucks had dwindled and trail-ready 4x4s with flexy suspensions were everywhere. Today, the 4WD world is arguably more diverse than ever with a wide range of modified 4x4s. Up until early ’02 all of the features I photographed were on transparency film and I have

thousands of outtake photos stored in bins. One of these days I need to dig into those, scan a few, and trot those 4x4s out in Firing Order. It would be a fascinating walk down Memory Lane. As I mentioned earlier, I enjoy meeting the owners of feature 4x4s and hearing the story of their rig, often told to me while I photograph it. It’s fascinating to hear why each owner chose their rig and why they chose to modify it as they did. For example, some built their rigs because that specific rig is appealing to them, while others chose their rig because it had a full frame. Some want a nice looking rig; others could care less what it looks like. Some owners build their rigs almost entirely of bolt-on aftermarket products, while others incorporate home-brew engineering and fabrication, and others use parts acquired used from online sites like Craigslist. In the end, these varied approaches to 4x4 customization and builds are often an extension of the 4x4 owner and what the owner intends to do with the vehicle. For example, the collection of rigs in this issue range from a Wrangler YJ to a fullsize van. And on this page you’ll see a small sample of the rigs we’ve featured in Four Wheeler, chosen from the last decade or so. Thank you for building cool 4x4s! It’s an honor to feature them. If you have a 4x4 that you’d like to submit for a potential feature in Four Wheeler please email a couple of high-res images and an overview of your rig to the email address below! –KEN BRUBAKER KEN.BRUBAKER@FOURWHEELER.COM PHOTOS: KEN BRUBAKER

SNOW STORY I lost my father the day before Thanksgiving 1992. The holidays were tough, and winter seemed long. Then came the blizzard of March 1993 in the Northeast. I had my brand-new ’92 Toyota pickup (22RE/five-speed) out in the midst of whiteout conditions and huge amounts of blowing snow. I put on 180 miles in two days of driving in town, out in the country, and wherever the spirit took me with not even a snow shovel on board. Young and dumb, yes, but cathartic, nonetheless. The next few years that followed had snowy winters which the truck handled no problem thanks to mods purchased from Four Wheeler. So, put me down as two big thumbs up for snow wheelin’! STEPHEN VIA EMAIL

RESCUED FC-150 PLOW RIG I enjoyed your article in the last Four Wheeler magazine on snow wheeling (Firing Order, Apr. ’22). My son and I have been old Jeep enthusiasts for many years. Attached are pictures of our ’62 Jeep FC-150 that’s still going strong. We use it at our northern Minnesota hunting camp to haul firewood and clear the many feet of snow that falls here each winter. I found this Jeep sitting in a rural junkyard in the Upper Peninsula of Michigan over 12 years ago. We hauled it home to Minnesota where my son Kyle completely rebuilt the driveline and tuned up the stock four-cylinder overheadcam engine. We had four new leaf springs custom built with an extra 3 inches of lift along with four new Rancho shocks. A set of 12x33x15 Ditch Witch tires and chains on the rears makes this old Jeep nearly unstoppable. Its cab is rusty, but our future plans include replacing and repairing some sheetmetal. We have more Jeeps in the pole barn for trail riding, deer and bear hunting rigs, and plans to start on a rockcrawler rig. There’s a ’48 CJ-2A, ’46 CJ-2A, ’46 CJ-2 Ag, ’77 Wagoneer with a 401ci V-8, and a ’79 Cherokee Chief with Quadra-Trac. We are Jeep fans from Minnesota and enjoy wheeling them in the snow and mud. Keep up your good work on keeping one of the last wheeling magazines on the newsstands!

SNOW: LOVE/HATE RELATIONSHIP In response to “Snow wheeling: Thumbs up or thumbs down?” (Firing Order, Apr. ’22), I can’t really answer your question as thumbs up or thumbs down. It’s a love/hate relationship here in Ohio. Love the snow, hate the salt.

I bought my ’00 TJ brand new because I was working full time while studying Engineering full time and needed a reliable vehicle. I wanted a four-wheeler but couldn’t afford both, hence a Jeep! I would drive 30,000 miles per year at that point in my life, snow or shine. I remember taking out after work and driving down roads with only my tracks and snowmobile tracks! Even in later years when I had a second vehicle, I would claim that my Jeep would sit during the salt months but when the white stuff fell I drove the Jeep. The frame on that Jeep finally rusted itself unsafe in 2020. I honestly thought that I took good care of the undercarriage, but little did I know that it was rusting from the inside out. Love snow, hate salt on my vehicles! JOSH VIA EMAIL

-> LOOKING BACK

Quadratec’s new Spare Tire Mount Backup Camera improves the safety and overall visibility of the Jeep Wrangler JK. Available for vehicles equipped with both factory and aftermarket stereos, the backup camera reduces the blind zone of the Wrangler, which is often blocked by oversized spare tires or other bumper-mounted accessories. The easy-to-install kit comes complete with a camera, black-powdercoated stainless-steel mounting bracket, plug-n-play wiring harness, and installation hardware. The Quadratec Spare Tire Mount Backup Camera features a 170-degree viewing angle with integrated fixed parking lines for maximum visibility. These guidelines can be deactivated during installation by bypassing the line wire. With a sealed zinc-alloy housing, the camera is corrosion resistant and features an IP68 intrusion rating.

-> LIFT YOUR 392

Skyjacker can help you raise your Jeep Wrangler Rubicon 392 to new heights in a bigger, bolder way with 38-inch tires. Keep your Jeep-tuned factory performance shocks but upgrade the OEM coils to a performance option. Skyjacker specifically engineered a progressive, variable-rate coil spring to coordinate with the Rubicon 392’s distinctive suspension handling characteristics. Spring rate progression is from a first flex rate to a second ride rate. The first rate stage of the coil spring delivers a comfortable ride with the ability to flex for increased articulation. The coil spring’s flex rate expands during full articulation as the suspension drops (full droop). This keeps the coil springs seated in the upper coil mount/bucket and the tires in contact with the terrain. The second rate stage only engages after compression past the first rate. Skyjacker’s proper geometry is said to ensure the Electronic Stability Control (ESC) system functions within factory parameters while the Lower Front Links’ and Upper Rear Links’ Eccentric Cam Bolts adjust proper driveline phasing and alignment. The kit also includes front and rear shock extension brackets, front and rear bumpstop spacers, front and rear sway bar endlinks, an adjustable front track bar, and much more.

The inflator can save up to four psi memory presets to expedite refills. The M18 Inflator is built with onboard attachments such as the inflator hose and nozzle storage as well as an internal cooling mechanism to extend service life. The M18 Inflator is fully compatible with the entire M18 line, which contains more than 200 power tool solutions. INFO: Milwaukee Tool, 800/729-3878, milwaukeetool.com

Help your 2.7L- or 4.0L-powered Toyota Tacoma stay cool with Mishimoto’s all-new performance aluminum radiator. Mishimoto’s radiator features a full-aluminum design and TIG-welded end tanks for a substantial improvement in durability over the stock plastic radiator. The radiator also features a 1.65-inch-thick two-row core with strategically designed fins. Packing more fins into the core is said to increase fin surface area by 84 percent, which has a direct impact on heat transfer and cooling ability. Mishimoto’s radiator incorporates a liquid-to-liquid stacked-plate transmission cooler into the end tank of the radiator, ensuring proper control of transmission fluid temperatures. Mishimoto’s Toyota Tacoma Performance Aluminum Radiator is a direct fit for ’05-’15 Toyota Tacomas and includes the company’s lifetime warranty. INFO: Mishimoto, 877/466-4744, mishimoto.com

Just. Everyone. Else’s. Parts.

yatt McAllister describes his YJ Wrangler as “just everyone else’s parts,” beginning with the 6.2L Detroit diesel. He’s on his second one of them and with the addition of a marine injection pump and injectors, heads from the 6.5L Detroit diesel, and the turbo out of a Cummins (and a handful of other modifications). The Wrangler clatters its way up and over rocks, through deep snow, and leaves onlookers bewildered as it slices across sand dunes. Wyatt’s NP435 came from a ’78 Bronco, and he used the Top Loader shifter from a 2-ton Ford for a shorter throw. Wyatt found the steering box from a Nissan Xterra to be the hard-core solution (kudos to its beefy sector shaft) to aiming his tires, and he mounted it as far forward as he could on the bumper to keep the unit from contacting his harmonic balancer. At each corner of the Jeep there’s a hydraulic system repurposed from a garbage truck that Wyatt uses to manually level (or tilt) the rig on side slopes or to help avoid obstacles. Each lower control arm is excessively overbuilt, and Wyatt will confidently smash any one of them against a rock with the weight of the nearly 7,000-pound Jeep. Out back, his 14-bolt rear diff is not shaved, instead, Wyatt welded 1⁄4-inch steel teeth to its bottom half to protect places where the pumpkin might encounter a rock. There’s much more to Wyatt’s YJ and to fully appreciate the details, you gotta see it in action. Look out for it on the Rubicon, where he can sometimes be found sans 40s, wheeling for charity with 31-inch dualies at each corner. 14 AUGUST 2022 FOUR WHEELER

White Whale

arl Limpus bought his first 4x4 in 2005 while he lived in Colorado—a ’00 Dodge Ram. The truck made Colorado winters a bit more fun, and its duties included daily driving and moving building materials about for Carl’s home improvement projects. Rockcrawling wasn’t even in the plans until he moved to California in 2009. With famed trails like the Fordyce and the Rubicon in his backyard, Carl’s goal for the Ram was twofold: First, he wanted to fit 37-inch tires into the wheelwells. This would enable him to volunteer as a driver for a grassroots veteran organization called Wheelers for the Wounded of California. The group pairs combat veterans with experienced 4x4 drivers for an all-expense-paid weekend of off-road fun on the Rubicon and Fordyce trails, offering the vets a chance to drive 4x4s on the trails, as well. Why build something so big? Like a Ram? Well, Carl also wanted to have space for his wife and children to join him on the trail, especially for the Father Daughter Rubicon Run hosted by NorCal Crawlers. The Ram went together entirely in Carl’s cul-de-sac and has since evolved to accommodate 40-inch tires. You’ll find him creeping through the trails that are oftentimes called “narrow” by drivers of short-wheelbase rigs, with expert precision. 16 AUGUST 2022 FOUR WHEELER

Imperfectly Perfect

oe Polcari’s search for a Land Rover took him (virtually) overseas, and it began in Spain. He wanted a Series he could fit with a V-8 and a manual transmission and really make it his own. After some sage advice from a friend, he locked eyes with the ’81 Series 3 Stage 1 seen here and knew that was the truck he wanted. The following 70 days were some of the longest of Joe’s life as he tracked his new truck across the ocean from Brisbane, Australia, to Baltimore, Maryland. Since then, the Series has been “the best worst car ever,” as Joe put it, explaining how it doesn’t do anything particularly well and how it’s even ended up on a flatbed a few times. To the contrary, the Series makes even the most mundane drives exciting, adding the sensory experience of a race car (just without the speed) and the ever-present question of “will it make it to the destination?” Joe removed the rear bench seat, built a mattress/cot setup for the rear of the Series, and with some hanging lights strung from the roof, the yellow Rover becomes an imperfectly perfect backwoods camper.

Grandpa’s Truck

hen Nick Miller was 15 and deciding which vehicle he’d learn to drive, he picked the ’71 Chevy Suburban that had been sitting for 18 years. Nick’s grandfather bought it new, his dad learned to drive on it, and now it belonged to Nick. He got the engine running, the brakes stopping, and eventually settled on an 8.1L big-block to motivate the sizeable machine. “Now that it went fast, I needed it to ride better,” Nick said, and with some help from the folks at ADS Racing, he fit the truck with a suspension to keep it going no matter what the terrain. Nick wheels the Suburban in the sand and snow as much as he can, doesn’t shy away from greasy mud-and-boulder tracks, and he enjoys using the trails outside the King of the Hammers race as a proving ground for his upgrades. Due to the sheer amount of factory sheetmetal and glass still in the rig, Nick uses extreme precision when navigating the trails, but he’ll tell anyone “it’s never not fun.” 20 AUGUST 2022 FOUR WHEELER

So, pointing his lifted Ford Econoline 4x4 at trails outside the King of the Hammers race in Johnson Valley, California, was nothing new. He found the van at an estate sale and originally bought it solely for its wheels. However, when it came time to hit the lakebed and his crew cab was still on the lift, he needed something exciting to wheel.

POINT YOUR PHONE CAMERA AT THIS CODE TO SEE A VIDEO OF VERNE’S THOUGHTS WHILE HE INSPECTS HIS OLD CJ-5.

Part 1: Piecing together a relic By Verne Simons editor@fourwheeler.com Photos: Verne Simons

e’d been looking for a decent intermediate Jeep CJ-5 (built between 1972 and 1975) for a while because our good friend Mike Tarvin has a ’75 CJ-5 we’ve always admired. His Jeep has the original AMC 304ci V-8 (which has a few tweaks), locking differentials, 3.15:1 transfer case gears (the factory gears in a Dana 20 are the not so desirable 2.03:1), and an NP435 transmission from a Ford truck swapped in for its granny gear. We wanted one for our own and so we could talk Mike into some more crazy adventures.

28 AUGUST 2022 FOUR WHEELER

FINDING THE PIECES Over the past year or so we’d come across a few intermediate and later Jeep CJ-5s, but nothing that was really what we wanted. We finally found a very nice, rust-free red ’73 body, tub, hood, front fenders, windshield, and more in a suburb of Phoenix and bought it. Then, a few months later, a yellow ’74 Jeep CJ-5 with an

fourwheeler.com

AMC 304 V-8, a wide-ratio T-18 transmission (with a granny gear), and more—that needed a nicer tub. Our idea was to make the two Jeeps into one and take the resulting intermediate CJ-5 to the Relic Run, a vintage-aimed off-road and camping event put on by the website Expedition Utah.

TEARING DOWN THE ’74 The clean, rust-free ’73 CJ-5 tub has a few stress cracks, but nothing bad and it came with most of the body, frame, front axle, transmission, and transfer case. Our plan was to piece it back together after gathering the missing parts. Later, we found the odd yellow ’74 Jeep CJ-5. It was running and driving and was in pretty good shape. It had a few issues, and the price was more than we should have paid, but instead of gathering parts, all the parts we needed for the build were there.

fourwheeler.com

Tech The ROAD TO RELIC Run The ’74’s frame, drivetrain, and engine all looked like they were fresh off a restoration. The tub was a mess, with tons of body filler in every panel and dubious repairs to the floors. The wiring was sketchy at best, with a fair number of butt splices, wire nuts, melted wires, and loose connections. It also had a Bestop soft top, factory rollbar, Dana 44 rear axle with 3.73:1 gears, and a limited-slip. The front axle is a Dana 30 with like gears and drum brakes. The ’74 also had power steering with several new parts. Also, at some point this Jeep had received some unmoving 4-inch-lift springs and new body mounts (held in place with loose, ungraded hardware). The coolest part is the wide-ratio, granny-geared T-18 transmission between the 304’s bellhousing and the Dana 20 transfer case. The T-18 is a bit stubborn to shift, but the granny gear is one of the things we wanted to swap into our ideal intermediate Jeep CJ-5 at some point anyway. We tore the ’74 Jeep apart to address the many loose nuts and also add on our more desirable (to us) ’73 body parts.

REBUILDING IN RED We then swapped the ’73 tub onto the ’74’s frame, keeping the engine, fuel system, exhaust, and drivetrain in place. It was quite the undertaking for the week or nine days we had before we’d need to leave for the Relic Run, but apparently, we thrive on the stress of a nearly impossible rebuild of a Jeep CJ-5 in a short timeframe.

30 AUGUST 2022 FOUR WHEELER

MAKING THE RED JEEP CJ-5 A RUNNER We added a Rebel Wire 8-Circuit Harness, a new copper/brass radiator from Summit Racing (more on that later), and a set of Milestar Patagonia M/Ts in 33x12.50R15 size (more on them later, too) on a set of old 8-inch-wide Ford wheels from none other than our pal Mike (the owner of the green CJ-5 that inspired this project). Then we began the 1,600-mile trip to Relic Run in the freshly rebuilt rig.

Tech The ROAD TO RELIC Run

WHAT IS AN INTERMEDIATE CJ-5? When AMC acquired the Jeep name in 1970, the company decided to make some changes that would allow the use of its AMC engines in the Jeep platforms. Technically, the intermediate Jeep CJ-5s were those built between 1972 and 1975, with early Jeep CJ-5s built from 1953-1971 and late Jeep CJ-5s built from 1976-1983. The most notable change for the intermediate Jeep CJ-5s would be the adoption of the AMC V-8 and I-6 engines. The AMC 304ci V-8 was installed in the Jeep CJ-5 as the first factory-available V-8 in the open top CJ Jeep line. The wheelbase was stretched 3 inches and the front fenders and hood 5 inches. The end result was a muscle car power-toweight ratio in the short and relatively tall CJ-5. Maybe this is the “American sports car” Enzo Ferrari was referring to when he supposedly said, “Jeep is America’s only real (or true) sports car”? The package is potent and, with a few tweaks, can be reliable and driveable on- and off-road. There were a few other changes with the introduction of the AMC powerplants like the swap to the Dana 20 transfer case (replacing the offset Dana/Spicer 18); an open knuckle, drum brake-equipped Dana 30 front axle; relocated fuel tank (to the back of the Jeep rather than under the driver seat); and a centered rear Dana 44 with flanged axles replaced the offset Dana 44 axle. Retained from the early Jeep CJ-5 was the underseat toolbox resting below the passenger seat and a similar frame and suspension.

he outline for Brian Jacobson’s dream Chevy Blazer was simple: it had to go fast through the desert, hold up to the rocks, and it had to be a classic. So, when he was pointed toward a ’69 K5 wasting away in a nearby backyard, he quickly went to work turning the languishing hulk into a functional 4x4. For Brian, building the Blazer was a deliberate process—he knew exactly what he wanted and wasted no time removing the body, stripping the frame, and gathering the parts he needed. With the help of Rock Bottom Off Road in Riverside, California, Brian acquainted the chassis with its new fire-breathing powertrain, lined up the linked suspension, and reinforced the mostly new Blazer body with custom armor and a full rollcage. At the end of the two-year build process, the restored and reimagined ’69 Blazer was ready for the dirt. Impressing friends and family was no sweat as the LS3 charged through the Southern California desert, and the Offroad Design links and King coilovers made easy work of rock gardens and sandy whoops. The Cavalry Blue paintjob and the Blazer’s all-around classic appeal continue to garner their share of attention, too.

INSTALLING the Powertrax No-Slip locker in an 8.8inch axle

1 1 Here’s the Powertrax No-Slip locker in its lunchbox-sized box. We got it from Summit Racing for about $470. Unlike a full case automatic locker, the No-Slip fits in the existing differential carrier. In this case, that’s a Trac-Lok 8.8 limitedslip case. To start the install, pull the differential cover and drain the gear oil. 2 Remove the cross-shaft retaining bolt and then remove the factory cross-shaft from the differential. 3 Push the axleshafts inward to remove the right and left side axle C-clips. We’ve found that using a magnet on a stick, or some needle-nose pliers, helps to get the clips out of the differential. The C-clips will be reused.

e’ve talked about “lunchbox lockers” before, but to review, they’re an inexpensive and easy way to gain traction for your 4x4. The fact is, most lunchbox lockers can be installed in an hour or two in just about any shop around the country with a little patience and some hand tools. Still, they have drawbacks, one of which is that they almost always can only be used in open differential carriers. So, when we heard about the Powertrax No-Slip for the Ford 8.8-inch limited-slip differential we were somewhat surprised and pleased. The No-Slip locker (PN 9206883128) fits inside the factory Trac-Lok differential carrier, changing what is probably a worn-out limited slip to a true automatic locking differential. We recently got a chance to install one of these lockers in our ’00 Ford Explorer project and found the install somewhat daunting, but in the end relatively easy. Follow along for the details and a few tips and tricks.

4-5 Next, remove the Z-shaped pre-load spring from between the two side gears. With it out, turn one side gear and remove both spider gears and their thrust washers from the carrier.

4 6 7

6 Each of the side gears slide out along with their respective clutch packs and thrust washers. Pro tip: Take the non-ring-gear side out first. 8 This is the coupler. There are two, one for each side. The one on the ring gear side of the carrier needs to be installed with the paddle opening (widest gap in the synchro ring, shown with an arrow) aimed toward you on the ring-gear side and away from you on the non-ring-gear side. Also, the gaps in the coupler must be lined up with the gaps in the synchro ring. Place the coupler in a vise and use the active spacer to align them if necessary. Place one C-clip on the ring-gearside axleshaft and pull the axleshaft into place. 10 But first you’ll have to install four saddle springs with grease or assembly lube into each of the two drivers. Then insert the ring-gear-side driver and spacer with the paddle facing you. Then install the non-ring-gear side driver and spacer with the paddle facing away from you. Each of the driver/spacers should key into the driver completely if the paddles and spacers are aligned properly.

7 Here are the parts that make up the Powertrax No-Slip. Note the new cross-shaft and the little baggie with several springs and a machined piece of steel that will come into play during the install.

8 9 10 11

9 Shown here is the driver (outside) and one of the active spacers (inside). The paddle on the spacer (black arrow) has to be lined up with the seat in the driver where the extended tooth is missing. The paddle and missing extended tooth of the driver (red arrows) will need to line up with the paddle opening on the coupler, so facing you on the ring-gear side and away from you on the non-ring-gear side. 11 This is what you should see at this point. The two C-shaped cuts in the drivers (for the cross-shaft) should be aligned and the eight saddle springs should still be in place.

fourwheeler.com

12 The next step is to install the inner and outer springs between the two drivers to hold the drivers and spacers in the carriers. To do this you will need to rotate the locker a quarter turn inside the carrier to access the hole where the inner and outer springs will live. 13 The inner spring nests inside the outer spring and both fit into the machined recess between the two drivers.

12 13 14 With the first inner and outer springs installed you should see something like this. In order to install the second set of inner and outer springs you’ll need to rotate the locker in the carrier 180 degrees. 15 Next, pop the springs in place like you did on the other side of the locker. It’s important that you keep the drivers and couplers on both sides engaged together so the orientation of the paddle and paddle spaces stay lined up. If not, the space between the two drivers will be too small to install the outer spring.

2022 GMC HUMMER EV We hit the trails in GMC’s first-ever battery electric supertruck By Jason Gonderman editor@fourwheeler.com Photos: Courtesy of GMC

hen the all-new battery electric ’22 GMC Hummer EV was unveiled in October 2020 the off-road world let out a collective gasp. The revival of the Hummer brand, once respected by off-road enthusiasts everywhere, as an all-electric sub brand of GMC wasn’t exactly what everyone was hoping for. Then the specifications were released … 1,000 hp, 1,200 lb-ft of torque, front and rear locking differentials, 35-inch tires with room for 37s, rear steering, and more than 320 miles of range. On paper, the Hummer EV seemed to be the real deal. However, we all wanted to know if the truck could live up to its Hummer namesake in the real world. With impressive speed, GMC brought the Hummer EV from concept to reality in less than three years, with the first production models rolling off the line in December 2021. Now, with deliveries happening every day, GMC invited us to jump behind the wheel and take the Hummer EV Edition 1 Pickup for a quick ride through some of 44 AUGUST 2022 FOUR WHEELER

the best off-roading the deserts of Arizona have to offer. So, does the ’22 GMC Hummer EV live up to its heritage namesake? Read on.

\Off-Roading the Newest Hummer

On the highway, the Hummer EV is phenomenal. How could it not be? The Edition 1 Pickup we were given to drive packs the massive 1,000 hp and 1,200 lb-ft of torque. This makes the truck incredibly quick, accelerating to its 106-mph top speed (electronically limited because of the 35-inch off-road tires) in the blink of an eye. The truck is comfortable, not particularly quiet, and draws massive attention everywhere you go. However, we were most intrigued by the Hummer EV’s claimed off-road ability. To test this, the folks at GMC took us on a short but informative off-road loop in the Arizona desert north of Phoenix. The offroad experience took us down graded gravel roads, through rock-strewn dry riverbeds, up steep rutted climbs, and along incredibly tight saguaro cactus-lined trails. While not fourwheeler.com

particularly long, the trail taught us a lot about the Hummer EV’s off-road chops. One of the first questions you may ask is, “What kind of off-road range does the Hummer EV get?” Unfortunately, we can’t speak directly to this until we get our hands on a Hummer EV for a lengthier test. However, we can speak to what we saw during our test day. Our day looked a lot like that of many off-road enthusiasts. We started the day by driving 75 miles on the road to the trailhead, wheeled through 20 miles of desert, and then drove 75 miles back to the start point. Starting with the battery reading 100 percent, we ended the day with 30 percent of range remaining. We used roughly 40 percent of range on the 150-mile road drive and the other 30 percent off-road. Obviously, your mileage will vary.

\High-Tech Off-Road Wizardry … aka Drive Modes Selectable drive modes are nothing new in the motoring world. However, in the past few years these different user-selectable options fourwheeler.com

FOUR WHEELER AUGUST 2022 45

FIRST DRIVE 2022 GMC HUMMER EV

have become increasingly intelligent. The Hummer EV comes with five drive modes: Normal, Off-Road, Terrain, Tow/Haul, and the user-configurable My Mode. GMC doesn’t include the three sub modes (WTF, Crab Walk, and Extract) in the official count. The two modes we focused our attention on most were Off-Road and Terrain. We know what you’re thinking, and we were, too, so let’s explain the difference between Off-Road and Terrain modes. All of the Hummer’s drive modes affect throttle maps, torque distribution, steering, the ability to adjust ride height, shock damping, braking, and interior sound enhancements. Off-Road mode is the go-to setting for general off-road driving. This mode gives a good mix of increased damping, a sensitive but manageable throttle, increased rear steering, and a more aggressive rear virtual locking differential (more on the virtual locking diff in a moment). Terrain mode takes everything up a notch and is the Hummer’s most aggressive off-road drive mode. Terrain mode damps the throttle pedal for smoother torque application in climbing and rock-climbing situations, features softer shock damping for better articulation than in Off-Road mode, and has the most aggressive traction control and rear locker settings. Most impressively, Terrain mode also increases rear steering angle to 1.2 times the front steering angle; more on that later. Terrain mode also offers two distinct drive modes within the drive mode, one of which enables one-pedal driving, which allows the driver to accelerate and decelerate using only the accelerator pedal. The Hummer EV does this by modulating regenerative braking, friction braking, and motor torque. Using the onepedal driving was quite an interesting feature off-road. We found it to be most useful when descending steep grades as a replacement for the traditional hill descent control, which the Hummer EV lacks.

\Front and Rear Locking Diffs? Yes, Kind Of … Much like the Hummers that have come before, the Hummer EV Edition 1 comes fitted with front and rear locking differentials. How does this work, you ask? Well, it’s complicated. Because the Hummer EV Edition 1 features three motors (one in the front and two in the 46 AUGUST 2022 FOUR WHEELER

rear), it has what GMC describes as a “virtual” rear locker. Essentially, when engaged by pressing the dash-mounted switch, the rear motors work together to simulate the function of a locked differential. While it would be simple to just program the motors to turn in sync, GMC’s engineers have made the system smart, allowing for differing levels of engagement in the available drive modes. During our time off-road with the Hummer EV, the rear locker worked exceptionally well. The biggest difference between this type of virtual locker and a traditional mechanical locking differential is that the Hummer’s virtual locker still allows for differentiation between rear tire speeds, which eliminates the scuffing felt with a locked differential. The front locker, which can only be engaged when the rear locker is turned on, is a traditional mechanical unit and functions like any other front locker.

\Big Wheel Travel for a Smooth Ride … In Theory The Hummer EV sports a claimed 13 inches of wheel travel from its fully independent suspension. On paper, this is right up there with Ford’s F-150 Raptor and Ram’s TRX. However, in practice, the Hummer EV has one major drawback to being competitive when it comes to its desert bashing ability: its heft. At more than 9,200 pounds, the Hummer EV weighs almost 2,000 pounds more than the aforementioned Ram TRX and 3,000 pounds more than the Raptor. To adequately support this heft, the Hummer EV’s air suspension needs to run at a higher pressure and with greater damping. In reality, this equates to an off-road ride that’s actually quite firm. At slow speeds on rough roads, the Hummer EV’s ride is fairly rough. Taking the speed up a couple notches helps to

smooth out the ride; when large bumps, whoops, or G-outs appear, though, the truck becomes unsettled quickly. Taken at face value, the GMC Hummer EV provides a pretty decent off-road ride. However, if you’re looking only at the spec sheet, you’re likely to be disappointed. The adjustable air suspension is good for quite a bit more than just ride comfort, however. Interestingly, GMC has programmed the Hummer EV’s drive modes to not adjust the ride height, leaving this up to the driver. Depending on the mode, the truck’s suspension can be raised by either 2 or 4 inches. The suspension also has the ability to lower by 1 inch for aerodynamics while driving, or 2 inches for WTF mode. Most interesting to us, however, is Extract mode, which raises the vehicle to its maximum height, 6 inches above normal. This is useful for getting the truck unstuck when it gets hung up on its belly or suspension, which we’ve all experienced.

\Rear Steering Steals the Show

We think the Hummer EV’s automatic rear steering is one of the most impressive features of the entire vehicle. Being more than 18 feet long and 7 feet wide, the Hummer EV is a large vehicle. As anyone who has taken a fullsize truck off-road can tell you, a vehicle of this size can make any trail quite challenging. This is where the rear steering function is a total game-changer. Before we get too far, let us say that, yes, the rear steering function can be completely disabled by the driver with a quick press of a button.

With the truck’s drive mode set to Normal, the rear steering works at a rate of 0.3:1 of the front steering angle. This means that if your steering input is 10 degrees, the rear will steer 3 degrees. When you switch over to the Off-Road drive mode, the rear steering increases to 0.6:1. And most impressively, when in the Terrain drive mode, the rear steering increases to an impressive 1.2:1. This means that, at its maximum, the rear is actually oversteering the front. On the road in Normal mode, the Hummer EV’s rear steering operates nearly unnoticeably. That is, until you try a U-turn. At that point, the truck’s impressive steering ability is shown in full force, allowing the long truck to make turns that would be otherwise impossible. More impressive, however, is the function’s use off-road. We were incredibly impressed by the Hummer EV’s incredibly tight turning ability fourwheeler.com

while navigating tight trails strewn with large bushes and cactus without adding the traditional desert pinstriping. As noted earlier, engaging Terrain mode enables the greatest amount of rear steering. With a ratio of 1.2:1, driving the Hummer EV in Terrain mode feels a lot like piloting a forklift. It’s weird and unnerving at first. After a few miles, however, driving with the rear end oversteering the front starts to feel like second nature. We were able to make tight turns in and out of washes, up hills, and around rocks with an ease and accuracy that we’d only previously experienced with small two-door Wranglers. Without this feature, wheeling the Hummer EV would feel more like piloting a heavy-duty longbed dualie, which we’ve done in the past (hasn’t everyone?)

\Wait, What About Crab Walk?

GMC has leaned pretty hard on the Hummer EV’s Crab Walk function for its marketing since practically day zero. Naturally, we were quite eager to try out this function. The press of a button on the center-console-mounted multi-function drive mode knob activates Crab Walk. A long press while stopped brings on a crab animation and exciting sounds. Once on, and while moving at slow speeds, the Hummer EV’s rear steering turns in phase with the front (which is opposite of how it would normally operate) up to 10 degrees. Aside from being a fun party trick to use in mall parking lots, Crab Walk is especially useful in certain off-road scenarios that drivers of large trucks and SUVs know all too well. Picture this: You’re driving up a steep, loose, off-camber trail and suddenly there’s a boulder that needs to be navigated around. Unfortunately, because of your rear locking differential, the truck’s rear end starts to slide down the grade. This wouldn’t be an issue if there wasn’t that pesky rock. Well, if you had the ability to crab by turning the rear wheels the same direction as the front, you could crab-walk the truck up the hill and around the obstacle with ease. That’s just one of the many helpful off-road uses for Crab Walk.

\Watts To Freedom

But that’s not all. We need to take a moment to address another interesting feature of the Hummer EV: Watts To Freedom. Watts To Freedom, or WTF for short, is a drive mode fourwheeler.com

in which the Hummer EV will perform at its peak. When activated, the truck’s suspension lowers to its lowest setting, the motors and batteries are conditioned (heated or cooled, depending on need), and a fun graphic and sound effect package plays for the driver and passengers. When prompted, the driver then applies full brake and full throttle. Lifting off the brake pedal sends the 9,200pound truck to 60 mph in 3 seconds or less, depending on the road surface and the battery’s state of charge. Thankfully, GMC set up a demonstration of Watts To Freedom for us in a large parking lot, allowing us to fully experience the full power of the Hummer EV without worrying about pesky exhibition of speed laws. All we can say is, holy cow, WTF mode is amazing. The whole process of getting the truck ready for a WTF 0-to-60 blitz takes only a few minutes, and the rush of spinning all four 35-inch tires is incomparable. And should there be a whole line of supercars waiting to be put to shame, WTF can be used again and again without any wait time between speed runs.

\Our Final Thoughts

While our time with the 2022 GMC Hummer EV was relatively short, we did get the answer to our burning question: Does the Hummer EV live up to its namesake? We can unequivocally say, yes, the all-new Hummer EV is the real deal when it comes to off-road ability. The truck is amazingly powerful, packed full of useful technology, and loaded with off-road hardware that really works. We’re confident, range anxiety aside, the Hummer EV could heartily take on the most difficult off-road trails in the country with little fuss. What’s left to be seen is just how many Hummer buyers actually get their six-figure supertruck dirty, much like the original Hummers.

A host of Steer Smarts parts right the wrongs on a Wrangler JKU 1

48 AUGUST 2022 FOUR WHEELER

1 Aluminum is hard to bend, but it will bend if you hit something hard enough. We’re guessing the previous owner of this ’18 Wrangler JKU knew he hit something when the tie rod bent. We may try to unbend this one and keep it for some future project.

fourwheeler.com

2-3 As said, this JK already had some decent steering parts installed on it, but even decent steering parts are dwarfed by these parts from Steer Smarts. This is the Yeti XD JK Top Mount Drag Link with Griffin XD Attenuator, perfect for this Jeep that had already been drilled for a drag link flip. The attenuator works kind of like a shock absorber for the drag link. Hard hits from the wheels get damped slightly before hitting the steering box or wheel.

e’ve used Steer Smarts Yeti steering parts before. Namely, the Yeti XD Series JK tie rod and drag link system on our 2017 Ultimate Adventure vehicle build, the UA CJ-6D. When we installed these parts back in 2017, we were gob-smacked at the size and beef that you get with these steering parts. Steer Smarts doesn’t skimp on the material, and rumor has it the parent company is a genuine OEM steering component manufacturer. That means well-engineered and strong parts that fit as

4 5

they should. That system, the one on the UA CJ-6D, has stood the test of time with no issues whatsoever despite years of heavy off-road use. So, when our buddy Eric bought a new and well-built JK for a family wheeler and daily driver, we knew just what to recommend when he noted that the JK’s aftermarket aluminum tie rod was bent (truth is, he told us these are the parts he wanted, and we agreed). We’re still not exactly sure how the previous owner of Eric’s new-to-him ’18 Recon Rubicon JKU bent the generally unbendable tie rod, but somehow it happened.

4-7 We also installed more beef in the form of the Steer Smarts JK Yeti XD Adjustable Front and Rear Track Bar. These parts are adjustable on the vehicle (like the drag link and tie rod) and are available with rubber bushings or in the Pro Series with polyurethane. We went with the Pro Series. Installation is simple, just be sure to coat the threads on the adjusters with antiseize. Also, a second set of hands or a ratchet strap or two can help line parts up during re-assembly.

Tech STEERED SMART

8 9 8 We also installed the Yeti XD JK Frame Side Track Bar Reinforcement Bracket. This bracket bolts in place using the supplied hardware. The part helps reduce any flex at the frame-side track bar mount position, which is great for any JK with oversize tires. 9-10 With most of the parts installed, we set the track bar parallel to the drag link using the track bar bracket holes in the Jeep’s aftermarket axle-side track bar mount. This helps prevent bumpsteer while lessening the angles of the drag link and track bar. The tie rod is the Yeti XD Pro-Series Aluminum Tie Rod Assembly for JK, which is another huge part that boasts forged steel tie-rod ends and a massive aluminum center adjuster tube that is machined for clamps rather than relying on jam nuts that can loosen up. The last step up front was to center the axle at ride height and use the Steer Smarts Toe Plate Alignment Kit. This kit makes setting the toe of your front axle an easy affair and it is well worth the cost of the product.

11 12 11-12 The last step was to install the Yeti XD Rear Adjustable Track Bar and center the rear axle at ride height. Did we mention that these parts are huge and thus should take your mind off any possible failure while on the trail? That’s 1 1⁄2 inches of solid E-coated and powdercoated forged steel and it ain’t bending anytime soon.

Either way, the Jeep needed some love in the steering and axle-centering department before Eric and his family undertook a cross-country overlanding vacation in the JKU. So, with a drag link, tie rod, steering stabilizer, and front and rear adjustable track bars in hand, we took a few hours one day to install all these bulletproof parts. In addition, we did a DIY steering alignment using Steer Smarts’ Toe Plate Alignment Kit. 50 AUGUST 2022 FOUR WHEELER

13 After the install we went for a test drive and then we re-checked everything. Thanks to Steer Smarts this Jeep’s owner won’t have to worry about any of the steering or axle centering components on this JK for many years to come. FW

t’s always a good thing when we get to this point in the life cycle of a long-term test vehicle and have nothing of any grave importance to report. Such is the case with our 2021 Four Wheeler SUV of the Year award-winning ’21 GMC Yukon AT4. After nine months on the road and more than 16,000 miles, the Yukon is still rock solid and we are just as enamored with the vehicle today as we were on the day it was dropped off.

During the first half of the year we spent a fair bit of time with a trailer in tow. With 355 hp and 383 lb-ft of torque on tap from the 5.3L V-8 engine, and a respectable tow rating of 8,200 pounds, the Yukon AT4 has proven itself to be a competent tow rig. The one area that we’re not as certain about is the adjustable air suspension while towing. The system has a number of positive attributes, with the most useful being automatic load-leveling and the ability to raise and lower the vehicle’s height while hitching. On the flip side, there are several small quibbles that we’ve bumped up against that we feel need addressing. The same automatic load-leveling ability that we enjoy on the road has made unhitching difficult on many occasions, especially when the trailer isn’t level with the vehicle, because it will continue to adjust even when the vehicle is off. We also have the 74 AUGUST 2022 FOUR WHEELER

setting activated that automatically lowers the vehicle down to the lowest entry level when placed in Park. This is great, except when attempting to hitch a trailer. We wish there was an easy way to lock out the air suspension when towing, as it would be quite helpful to have full control over the suspension without the vehicle doing anything automatically. Additionally, we got a strange error message while towing a side-by-side on our utility trailer. The full load was about 5,000 pounds with approximately 500 pounds of tongue weight, well within the Yukon’s limits. Upon arriving at the desert and unhitching the trailer, the vehicle flashed “Height adjustment unavailable, air suspension overloaded.” It took several miles of driving and key cycles to get this to clear and allow us to bump into the higher off-road suspension settings. We hadn’t seen this prior, and haven’t since, so we’ll be

watching for it in the final quarter. Speaking of the Yukon AT4’s air suspension, we ran some incredible off-road trails this quarter and had a chance to use all of the vehicle’s off-road hardware. With the Yukon’s transfer case shifted into low-range we were able to raise it into the highest suspension setting, which provides an impressive 34.5degree approach angle, 22-degree breakover angle, and 10 inches of ground clearance. We waded through two feet of water, drove through soft sand, climbed steep hills, traversed rockstrewn riverbeds, and blasted down graded roads. About the only thing we didn’t do was hard-core rockcrawling … for obvious reasons. We still appreciate the Yukon AT4’s electronic rear limited-slip differential, which works quite well when traction starts to decline. Selecting the Off-Road drive mode (the Yukon AT4 features Normal, Tow/Haul, Off-Road, and Sport drive modes) improves throttle mapping and transmission shifting when in the rough. And the Yukon AT4’s standard hill descent control is certainly useful for those who choose to use it. Like most air suspension-equipped off-roaders, we’ve found the Yukon AT4’s ride fourwheeler.com

Even at full street tire pressure, the Yukon AT4 is a dream on graded dirt and gravel roads like this one. With the suspension at “Normal” ride height and the transfer case in “Auto” we can easily fly down these roads in comfort. The adaptive ride control dampers easily soak up all the bumps and humps.

OPTIONS AS TESTED

The combination of our Yukon AT4’s Cayenne Red paint, dark chrome trim, front skidplate, and off-road tires gives the vehicle quite the sinister look. And it has attracted attention everywhere we go. People simply love the Yukon AT4. With the transfer case in low range, the Yukon AT4’s air suspension can be raised two inches above the normal ride height. This gives the Yukon an impressive 10 inches of ground clearance along with 34.5 degrees of approach angle, 22.5 degrees of departure, and 22.0 degrees of breakover. We would still love it if GMC could find a way to package the fantastic 3.0L Duramax diesel I-6 engine from the Yukon Denali in the AT4. Allegedly, the AT4’s front skidplate interferes with the diesel engine’s charge air cooler. Still, the prospect of 460 lb-ft of torque with 26 mpg on the highway is quite enticing. We’ve stuffed adults in all three rows of the GMC Yukon AT4 and have not had a single complaint. The middle row captain’s chairs both recline and slide, while the third row now has much improved legroom thanks to the Yukon’s new independent rear suspension. Impressively, there are even USB-C charging provisions for all except the rear center passenger.

quality degrades significantly the higher it is raised (it’s still better than most, however, thanks to the active ride control dampers). While the extra two inches of ground clearance is nice when going over large obstacles, we’ve found that the normal ride height is the most comfortable for most general off-road scenarios. Unfortunately, it looks like we’re going to go another year with no opportunity for snow or mud wheeling on the West Coast. While we’re confident in the Yukon’s snow ability, we’d try our hardest to avoid deep mud holes, but that’s more a personal preference anyway. Moving back inside, the interior continues to prove to be a comfortable fortress of solitude, most of the time. If we were going to spec out the Yukon AT4 again we can say at this point we’d find a way to not have the panoramic sunroof. Personal preference plays a large role in this. However, we’ve found that the glass roof and cloth cover let in quite a bit of heat and noise. Unfortunately, the sunroof is grouped together with the AT4 Premium Plus Package so it would take some clever optioning to get the features we love without the glass roof. Another polarizing feature that we love is the head-up display. We leave it on speed most of the time, but it has the ability to display off-road data, stereo information, and navigation. It’s become such a useful tool that we don’t know how we’ll live without it when the Yukon returns to GMC. As we enter the final quarter of evaluation, we’re displeased by the proposition of returning the ’21 GMC Yukon AT4 to its rightful owners. Having just completed the second scheduled fourwheeler.com

WHAT’S HOT, WHAT’S NOT

service at 15,000 miles, we don’t foresee another dealer visit. So, all that is left for us to do is enjoy our remaining months with the large SUV. Sticking with the plan that’s worked so far, we have more off-roading, towing, and road trips on the books. Here’s hoping for another trouble-free quarter as we send the Yukon AT4 off in style.

console, contains the SUV’s wireless phone charging pad. Simply drop your device on the pad and it will automatically begin charging. Trouble is that our standard-sized iPhone isn’t large enough to stay centered and would frequently drop the charge just by slipping to one side or another. Needless to say, this spot now just collects junk.

Hot: Gorgeous styling continues to attract attention, 5.3L V-8 engine is plenty powerful, all seven seats are comfortable for full grown adults Not: Panoramic sunroof is good for watching the carwash brushes and not much else, fuel economy is still on the lower end, wireless Apple CarPlay has gotten a tad buggy

LOGBOOK QUOTES -> “I’m really glad the Yukon has a small gas tank now, as it takes two card swipes if I let it go below a quarter tank … yikes.” -> “We have FINALLY found a good use for the sliding center console! It perfectly holds the giant tub of cheese puffs for road trip snacking!” -> “The compliments keep pouring in for the Yukon AT4, from the old man at the gas pump to the parents at Disneyland and everywhere in between.” -> “Just went through a deep water crossing in our factory AT4 while laughing at all the kitted-out Jeeps that followed.” FW FOUR WHEELER AUGUST 2022 75

Feature GRANVILLE SALUTE Due to many requests, we’re republishing some of Granville King’s “From The Backcountry” columns as space permits. These columns ran in Four Wheeler from 1984 until Granville’s passing in 1989 at age 70. Granville was a retired aerospace engineer and television screenwriter who lived off-grid in a trailer in Baja, Mexico. His off-road experiences were many, and his storytelling was amusing, riveting, timeless, and unparalleled.

Visiting the Yuma Proving Ground and the LeTourneau Overland Train

our Wheeler’s July 1969 issue took us to a special part of the desert where the Devil vacations when he needs some heat. Just north and east of Yuma, Arizona, sits the expansive facility known at the time as the Yuma Proving Ground. Its location makes it favorable for year-round testing with higher-than-average temperatures and some of the lowest precipitation levels around (in 1968, 1.2 inches of rain fell). The Yuma Proving Ground allowed the Army to subject its vehicles to extreme temperatures, deep water crossings, onslaughts of silt to detect dust intrusion and resistance, rocky ledges and punishing washouts to verify structural integrity, and even drops from supply planes. Among the wheeled and tracked vehicles designed and evaluated at the Yuma Proving Ground, one hulking behemoth caught our attention: the LeTourneau TC-497 Overland Train Mark II. The concept began with logging in mind as a way to transport felled timber away from sites through undeveloped terrain. LeTourneau’s VC-12 Tournatrain was the first iteration, and it was fronted by an engine car fit with a 500hp Cummins VT-12 and a generator. Each car that followed had four wheels and tires, each powered by its own electric motor. A later version of the land locomotive, the VC-22 Sno-Freighter, was used in the arctic regions of Alaska to deliver materials to the Distant Early Warning (DEW) radar stations. This locomotive and its six individually powered cars floated over snowdrifts and crossed rivers with 10-foot-tall pneumatic tires. In addition to moving loads over the frozen tundra, another of LeTourneau’s over-the-snow haulers, the TC-264 Sno-Buggy, gained notoriety for donating its tires and wheels to the Bigfoot 5 monster truck. Following the success of the previous LeTourneau trackless trains, the United States Army contracted the TC-497 Mark II. This train traded Cummins diesel power for a quartet of gas turbine engines with a better power-toweight ratio, and the ability to expand the train to greater lengths. Four 1,170hp Saturn 10MC engines were spread throughout the train, one in the head car, and the three others dispersed among the trailing cars. In addition to their own electrically driven wheels, all cars were designed to steer individually. Signaling each

car to turn at the same point allowed the train to round challenging corners and avoid obstacles. The Mark II was built from aluminum and due to the smaller size of the gas turbine engines, there was room aboard for a crew of six with space for dining and sleeping. The train was 30 feet tall, could carry 150 tons of material, and measured 570 feet long with the ability to extend its payload with additional fuel and cargo cars. The train was tested at the Yuma Proving Ground and was known as Project OTTER (Overland Train Terrain Evaluation Research). Despite its remarkable capabilities, the train was abandoned with the advent of cargo

helicopters. Although most of the overland train was reduced to scrap metal, you can still see its control car at the Yuma Proving Ground. In conjunction with the Army, General Motors has more recently built its Desert Proving Ground within the government test site, allowing for the discreet development and testing of consumer vehicles in the punishing desert environment, far from prying eyes. If you have a personal account of overland arctic travel or have ever met any of these land trains face to face, please tell us about it by sending a note to editor@fourwheeler.com. Don’t forget to include high-resolution photographs, if you have them. FW
