The 800 pound gorilla in the room is “What happened to Patterson”, and you will find a very well written explanation on page 12. We practiced good governance for GMCMI, and took every opportunity to protect our membership. The 2022 Spring Mailing contents are: this magazine, the GMCMH Parts Interchange, GMCMI Article Index addendum (one page, covering 2021 additions). We have produced a revised 2022 GMCMI Article Index pdf that is available in the “members only” section of our website. In coordination with Billy Massey, the “Black List” will be distributed in print every other year. A pdf of the publication is available at GMCMI.com, or wwww.bdub.com. As I write this, I have been on a “Black List” call, and am helping a stranded GMC’er. I know you have heard this before, but it is worth repeating. By far, the best part of a GMC Motorhome is the community. You are the best. The Black List lets us all endeavor to keep it that way. There will be a GMCMI survey sent to you. It is only five questions and your feedback is critically important to set the tone and direction of GMCMI. If we do not have an email address for you, it will arrive in your postal mail. Please take the time to reply. You are going to see some exciting changes in how our Spring 2024 Convention is marketed. Check out the back page and the explanation of the change on page 7. It is going to be the “Vintage RV Rally SE2024” hosted by GMC Motorhomes International. A convention is the best point to observe the total solar eclipse! It is still us, with the same great GMC Motorhome specific presentations, but we are inviting other vintage class A coaches to come out and play. I know it is going to “eclipse” anything we have done before. You know it is going to be a great time, and a great time with more people is, – DOLPH SANTORINE, well, just greater! GMCMI PRESIDENT

“Registration Is Open!”

Registration is open for our 2022 Fall 40th Anniversary Convention in Lebanon, Tennessee! You can register at www.gmcmi.com. It is in a great location with lots to do. I sincerely hope to see you there!

Dolph Santorine

Such has been the case with the leadership of GMCMI. The board had agreed to stay on for 2021-2022, and the nominating committee has all the pieces in place for the fall elections. I know it is an amazing team that has held together through the most trying times. I am proud of what we have accomplished in under less than optimal conditions.

While we all have our unique way of planning and budgeting for travel, my typical trip had about 15% for fuel. That is now 30%, but the largest part of our budget is for the rest of the things that we do along the way and where we are going. Traveling about we have seen more people at campgrounds and state parks than ever, so it requires just a bit more planning. With care, a few miles per hour slower, we can have fun, and stay on budget. We can do this! So, while the eldest of our motorhomes are turning 50, our association is turning 40. The future is looking bright!

Spring Mailing Delay

GMCMI Status

I would like to apologize for the delay of the 2022 Spring mailing. The Weeks’ household pretty much lost the month of May. Both of us contracted COVID and then after about three weeks of recouping, Keith experienced a heart attack, complications, and finally a stent. An additional procedure is in the future. Thank you for your kind words, understanding, and patience.

Membership stands at 795. We have 35 new members since our last publication.

Ben 10 The original series (consisting of 13 episodes), was created by Man of Action Studios. The pilot episode aired on December 27, 2005, as part of a sneak peek of Cartoon Network’s Saturday morning lineup. The second episode was shown as a special on Cartoon Network’s Fridays on January 13, 2006, and the final regular episode aired on April 15, 2008.

BY JANET FREY | GMC VINTAGE RVING MAGAZINE EDITOR

Just when we thought we knew everything about the GMC Motorhome toys, marketing logos, packaging

The series gradually became popular among audiences and received numerous accolades, including three Emmy awards. It earned a massive $6 billion and with a run of 15 years, this is the longestlasting franchise in Cartoon Network history (fact from a story dated March 16, 2022). The cartoon would go on to spawn the following: Ben 10 was succeeded by Ben 10: Alien Force, Ben 10: Ultimate Alien and

materials, and signs; we have found another one! THIS ONE IS OUT OF THIS WORLD! There is a cartoon series, movies, and toys featuring a young boy named Ben 10. His claim to fame is obtaining an alien device resembling a wristwatch that allows him to transform into 10 aliens. How does the GMC Motorhome fit in? Well, apparently Ben’s grandfather has a motorhome that looks suspiciously like a GMC. The largest drawback to this identity is that it has rust and is called the “Rust Bucket”. Now, we all know that a GMC body does not rust – it is aluminum and fiberglass. The motorhome is never identified as a GMC Motorhome, but, hey, just One lucky person will check out photos at below!

GMC VINTAGE RVING MAGAZINE | WWW.GMCMI.COM

While taking photos of the two boxes we noticed that they were different. The toys are the same but notice Ben appeared older and the Ben 10 logo was different. With a little research we discovered there is a series of different logos. Logo used from 2005-2008

Logo used from 2008-2012

Ben 10: Omniverse. A fifth series, and reboot in 2016.

Rust Bucket | Original Series

Our GMCMH Historian Bill Bryant mentioned that did not publicize the toy because of the rust. He commented, “It was too bad that the creators implemented the rust on the GMC Motorhome.”

The original series also has three television movies based on it; Ben 10: Secret of the Omnitrix which serves as the grand finale of the original series as an alternate universe live-action adaptation, Ben 10: Race Against Time (notable for starring Lee Majors as Grandpa Max), and a 2012 all-computer generated imagery film called Ben 10: Destroy All Aliens. You can watch many of the episodes/ series free by Googling. They are also listed at: https://www.imdb.com/title/ tt0760437/. Storyline A 10-year-old boy named Ben Tennyson is on a summer vacation road trip across the United States and back with his cousin Gwen and their Grandpa Max. Grandpa is in his 60’s, rather a large fellow and a bit slow at times, but a somewhat handsome chap. His past life was a plumber. He retired but still fights aliens in his free time with a keen sense for adventure and a strange taste in food – the only thing that Ben and Gwen do not argue about. On their first night camping in their grandfather’s motorhome affectionately named the “Rust Bucket”, Ben finds an alien device resembling a wristwatch named the Omnitrix. The device which contains DNA of different alien species permanently attaches itself to his wrist giving him the ability to transform into a variety of alien life-forms each with

its own unique skills and powers. With his newfound superpowers Ben must learn the responsibilities of being a hero. During their vacation, the Tennysons are attacked by various enemies ranging from space aliens to supernatural entities.

Ben 10 Toys The Ben 10 Max’s DX Laboratory Play Set is housed in a replica of Grandpa Max’s motorhome the “Rust Bucket”. Despite having state-of-the-art armaments and capabilities, the Rust Bucket has a faulty toilet and a broken air conditioner. It was destroyed sometime before the events of the flashbacks in the Omniverse series The “Rust Bucket 2” is Grandpa Max’s replacement motorhome which is outfitted with much of the same technology as the original, including jet propulsion and advanced laser weaponry. It is nearly identical in appearance to the first Rust Bucket, but is missing the satellite dishes and antenna from its roof. The Rust Bucket 2 also has blue-tinted windows, whereas the old Rust Bucket’s windows were black-tinted. Final Thoughts If you have not had a bit of a laugh about all this, have a glass of wine and read it again! Really, who knew that a GMC could be so unique? To me, it seems like Ben 10 and his adventures are a PG version of the Stripes movie. And it shows once again, that the GMC Motorhome is a one-of-a-kind creation that keeps being rediscovered – even after 44 years have passed since the last one was built!

Rust Bucket 2

Another GMCMH Toy? While doing research of this toy we discovered a photograph of a lego Ben 10 “Rust Bucket”. We believe this was a kit because of the custom grill and antenna pieces. Have you seen one of these?

Lost and Found! Kim Weeks | GMCMI Convention Manager

Do you need a surge protector for your RV? While it is tempting to just plug into the campground pedestal, it is important to make sure there are not any problems which can damage your electrical system or electrical components and appliances. During my research, I discovered two options, the surge protector and the energy management system (EMS) for our coach’s electrical systems (30 amp or 50 amp). So what is the difference? A surge protector is designed to protect from low voltage, open ground, open neutral, reverse polarity, and accidentally plugging into a 240-volt outlet. An EMS monitors power usage and makes adjustments to the loads to reduce tripping of the pedestal breaker. Some EMS models will even have a readout to show you what fault occurred.

Folding Drying Mat The Cuisinart Dish Drying Mat with Rack is ideal for the GMC Motorhome. This fast-drying absorbent microfiber mat holds a variety of cookware and dinnerware then folds up for storage. Can be purchased at Walmart or Amazon. Editor’s Note: You could win a dish drying mat and rack at the 2022 Fall GMCMI’s 40th Anniversary Convention in Lebanon, Tennessee!

What do they cost? Searching the internet I found them priced from $100-$500, but it could pay for itself in just one night connected to a defective pedestal.

were warmly welcomed by our members. Because of this success, our administrator thought that it is time for another venture.

Instead of being advertised as the GMCMI Eclipse Spring 2024 Convention, we will be advertising as a “Vintage RV Rally hosted by GMCMI” during the total solar eclipse. What is in those words?

Second, the selection of words is critical for promoting this event. When researching the process to advertise the Convention, we discovered that words like “vintage” and “rally” were much more effective in making the connection to the owners that we want to reach.

Several things: First, it will not be an exclusively GMC Motorhome gathering. As we did in the Spring of 2017 at the “Vintage Motorhome Celebration” in Shawnee, Oklahoma, GMCMI is inviting owners of other vintage class A motorhomes to come and participate. In 2017, four motorhomes joined us: 1989 Winnebago Spectrum, 1974 FMC 2900, 1984 Airstream 300LE, and 1982 Revcon. The owners were impressed by our organization, and

There are important features that will not change. There will still be our signature seminars, tech info, fun activities, and fellowship. The rally will still be a Convention…. just a rose by another name! So mark your calendar to plan to attend the “Rally” in Mineola, Texas. And be prepared to have an out-of-this world experience!

The McLaughlins Share Memories BY MARGIE McLAUGHLIN (AND LARRY TOO) | 1976 PALM BEACH | MONCTON, NEW BRUNSWICK, CANADA

We started “GMCing” in 1976 with our first coach which was a 1973. I forget the name but it was a bright orange color, had shag carpet, and fit in quite well with the 70s disco era. It carried us and all five children from home to Disney World and back, the first trip out. We then swapped it out for a 1974 and Larry was not happy until he acquired our current 1976 Palm Beach. We have logged thousands of miles on the Palm Beach, and it remains the nicest coach we have ever seen. It has taken us to every province in Canada, every one of the lower 48 states and through Alaska twice. Along the way we have met the nicest people ever and made most of our best friends through motor coaching. Nothing makes Larry and me happier than getting a call out of the blue that some GMCMI’er saw our name in the

membership directory and is going to drop in to see us in Moncton, New Brunswick. Our first GMCMI Convention was in Bethlehem, Pennsylvania, (GMCMI’s third rally in the Summer of 1983 with 103 GMC Motorhomes) back when the GMCMI Conventions were connected with FMCA events. What an eye-opener as we came over the hill and saw hundreds, maybe a thousand coaches sprawling over a huge field-turned campground/rally site. At the time a fellow named Ralph Luby organized all the GMCs to park together. We have both served on the GMCMI board in senior capacities and I was the first Ladies Editor of the

GMCMI newsletter. The Ladies always had lots of productive things to do while the men sat around chatting about things that “they claimed” to be experts on. The ladies even started a GMC chapter of the International Red Hats Society. Another one of our major undertakings was making quilts under Jeanne Robinson’s guidance. We made a few quilts at each rally and donated them to a special “deserving group” The last quilt we made had a special GMC significance and was done at one of the anniversary rallies. All the ladies who helped on it put their names in a drawing and yours truly was the lucky winner. That quilt still gets snuggles on our GMC weekend outings. We have been to more GMCMI Conventions than I can count but I can say we have made ten

GMCMI Spring Convention | April 22-28, 2022 Patterson Area Civic Center | Patterson, Louisiana

The Cancellation & the Future BY KIM WEEKS | GMCMI CONVENTION MANAGER

When I think about what is happening around us, I quickly settle into one concept: change. A remember a famous quotation by Bob Dylan, “There is nothing so stable as change”, this may be hard to accept, but I ask myself “what am I going to do about that fact?” Change may have its downsides but it will push us into becoming more creative. In retrospect, GMCMI was fortunate to have our Fall 2021 “Welcome Back” Convention in Chippewa Falls, Wisconsin occurring after the Delta-surge and before Omicron. Our theme “Welcome Back” was a big success and all can agree the theme was carried off. Thankfully, we did not have evidence of any spread of COVID-19 associated with the Convention. GMCMI was not as fortunate with the Spring 2022 “Cajun Crazy” Convention in Patterson, Louisiana. We originally contracted on holding the 2021 Spring Convention in Patterson but due to the pandemic, it was canceled and rescheduled for 2022.

Cancellation One of the hardest task with being your Convention Manager was to consider the cancellation. Your GMCMI leadership understood that the cancellation may cause inconvenience and disappointment for attendees, presenters, and vendors, but in consideration of the health and safety of all attending, the decision was made. 12

Thank You As we learn how to navigate these uncharted challenges, we appreciate your patience and understanding and wish to take a moment to say “Thank You”. You are what fuels GMCMI and ignites our passion for creating incredible experiences such as the GMCMI Conventions. Thank you to the Patterson pre-setup team of Fred & Sharon Hudspeth, Richard & Jaye Hodges, Randy & Margie VanWinkle, Lori Ferrara, Don Fenwick, and Bob Hughson. Due to my testing COVID positive on arrival, several of the team members were tested and as a precaution placed on COVID treatment. Thankfully, because of the treatment administered and isolation measures implemented, there were only three team members infected. With unusual circumstances our veteran team members jumped into action and assisted with tasks that I could only view from the other side of a glass door, screen share, facetime, or via phone calls. It was an unsettling time for all but the team stepped up and completed the tasks at hand.

Future Conventions & Events Reflecting on the importance of the GMCMI Conventions in keeping the technical and social fabric of our Community strong, and as we evolve, with youth filling our Community, the importance of these hands-on experiences

GMC VINTAGE RVING MAGAZINE | WWW.GMCMI.COM

are critical to the future of the GMC Motorhome, GMCMI, and maintaining the GMC Community. In the last two years, the GMC Community communicated on several electronic platforms where relationships were developed with individuals that we have never shaken hands with before. Most of us wish we could return to the pre-COVID norms of December 2019, but that is not likely to happen.

Some Parting Thoughts Future Conventions will be planned with COVID over our shoulder, impacting what is scheduled and how it is scheduled. This is what any group must do when planning large gatherings. But this does not mean that we have to avoid or give up our gatherings. It does mean that we must be prepared and respect guidelines and common sense to provide safe events and fun times. So, while it is important to reflect on what happened, it is also important to move ahead and use courage, commitment, and determination as our guide.

In Closing I wish to extend my hope for everyone’s health, safety, and enjoyment in 2022. As previously stated, it is time for us to “become more creative” so let’s come together and celebrate GMCMI’s 40th Anniversary this fall in Lebanon, Tennessee. See you there!

Once upon a time, a dark and evil virus spread around the world. It hit the big cities, it hit the small towns, and even found its way to the civic center in Patterson, Louisiana. This diabolical disease forced the cancellation of the Spring Convention.

Saddened by the cancellation, a few Dixielanders, still determined to meet, gathered at Buccaneer State Park near Waveland, Mississippi, for the scheduled no-host rally. New friends were made and old friends reconnected. Bill and Midge Kitteridge, new Dixielanders, joined the usual suspects – the Phipps (the unofficial no-host, hosts); the Richardsons; the Nicholls; the Chimentos; and the club’s fearless leader, Madam President and her first spouse, the Michelhaugh. Another GMC was spotted in the campground, and Tom invited them to join the assembled group adding the New Jerseyites Gene and Marlies Bunt to the group.

Since it was a gathering of GMCers, food was involved. Yummy goodies magically appeared for a potluck or two. Local eateries such as MacBe Seafood, a hole-in-the-wall establishment, filled everyone’s plate and stomachs with great seafood… numerous to-go containers returned to the coaches. Another dining adventure brought the group to Avocados Mexican Cantina. Adult recreational beverages and a vast selection of food graced the tables. The evenings ended with campfire ring gatherings. Thank you Bill for providing fire and warmth. We sat around the fire and swapped stories…the most interesting ones were stories about how we found our first GMC. The morning started with “BYOC”, bring your own coffee, and breakfast foods magically appeared from coaches. We talked about places we planned to visit: • the Waveland Ground Zero Hurricane museum gave the visitors a feel for the destruction of Hurricane Katrina. • the Bay St. Louis Historic L&N Railroad Museum. Yes, one would expect to find train-related displays. However, entry into the museum felt like walking into a Mardi Gras (MG) ball. Upstairs held another unexpected treat – an art museum

A GMCMI Member Profile BY JANET FREY | GMC VINTAGE RVING MAGAZINE EDITOR

ANDREW CUDLIPP came to our attention when we became aware of his YouTube postings involving maintenance and repair of the GMC Motorhome. It seemed like a good idea to get in touch with this new GMCMI member and learn more about him. I was curious as to how he became involved with the GMC Motorhome since he is only 27 years old. He explained that in his teenage years, he saw an internet story about vintage motorhomes, and it included the GMC Motorhome. He did not think he would ever need a motorhome, but he was fascinated by them at the time. Fast forward ten years and his mother wanted to get an RV and something unique. He swayed her in the direction of a GMC and so the search began. Together they scoured the internet looking for her perfect coach, learning as much as they could along the way (since neither had ever seen a GMC in the flesh). Finally, they found a 1978 Royale in Wisconsin, bought it within a week, and together drove it on a perilous journey to her brother’s house in Oklahoma. It was right around Thanksgiving and the weather was a bit crazy but the coach ran strong. There it sat for a while since they lived near Seattle and covid had restricted many activities. But in the meantime, Andrew discovered that mom would not let him borrow the GMC. He needed to get his own. Andrew has a prosthetic leg and enjoys riding scooters, since motorcycles are not really an option. As a kid, he says he would “ride all over town, I knew all the back-alleys and side streets”. One day after work, and still during covid, he spotted a familiar shape Andrew’s scooter through a garage door in his downtown area. Inside were two GMC Motorhomes apparently stored for many years (he found out later that it was nearly 20 years!). For a while he would make a point to stop by on every ride, hoping to catch someone there or get a contact. That lead to nothing, and he wondered how he would be able to contact someone. His Mom gave him the idea to look up taxpayer information for the address on the city website, an idea that worked brilliantly! Andrew got an address, mailed a letter on Wednesday, got a call on Saturday, and made the deal on Sunday. The family was very nice and negotiated a deal for Andrew to take both coaches, a pair of 1976 and 1977 Eleganza II’s. Fortunate that he was able to purchase them when he did because the gentleman passed away some months later. As part of the deal, Andrew was able to use the historical building to fix up the motorhomes, a place which he later found out was originally a WWII-era Buick dealership. Over the years it changed hands many times, being a Ford, Lincoln, and Mercury dealer as well as the set for Andrew’s fantastic YouTube videos (the hardwood floor is a real spectacle!) 14

1977 Eleganza II

With his background as a self-taught mechanic, he was able to film the YouTube videos and complete the work. NOTE: Andrew, as a teenager, had his heart set on getting an old-school BMW and fixing it himself. He now manages a fleet for a landscaping company, working on everything from excavators to trucks and mowers. Anyway, when Andrew was deciding what to do with two GMC Motorhomes, he concluded that he would keep the 1977 for himself, and eventually sold the other one to his best friend Mike, a fellow scooter buddy. Mike needed a place to live and now loves the GMC lifestyle. Andrew enjoys working on the GMC, and its straightforward mechanics. He says he prefers old things, and that as long as you are not a gorilla, you can deal with the repairs and keep it on the road. Since he has only had the GMC out of the garage a short time, and is also a new dad, he has only put 500 miles on it so far. Andrew happily posts updates on the various Facebook pages and groups, and that is how another interesting part of Andrew’s story came about. When he posted the video of Winifred Mike’s ’76 Eleganza leaving the garage for the first time in 20 years, one GMC group member gave an amazing response! The front spoiler turned out to be a dead giveaway that the coach might be his father’s GMC that he purchased new back in New Jersey! They got in touch and using service stickers from behind the vacuum cabinet, Michelle, Wini, and Andrew they identified it and got a complete family history and photographs from back in the day! It is quite an amazing story! Hopefully, we will see Andrew, his girlfriend Michelle Troxler, and baby Winifred (Wini) at a future Convention.

Maintenance for New Owners

Ty Hardiman | 1977 Kingsley | Norman, Oklahoma

GMC Motorhome 101 is a recurring column written for owners who may be new to mechanic work but have an interest in learning how to perform their own repairs. We cover common GMC maintenance projects that can be accomplished with basic tools. Our goal is to perform this work ourselves while aiming to achieve the quality found in professional mechanic shops. Over time we will gain confidence, save money, and increase the reliability of our coach. The parts needed to perform the work in this column can be purchased from GMC vendors that support our community by their membership and participation in GMCMI. Many parts will also be available at auto parts stores.

The Rochester Quadrajet Fuel Filter The carburetor that provides fuel to our GMCs was manufactured by the Rochester division of General Motors. GM called the carburetor design “Quadrajet”. The “Rochester Quadrajet” was used in all of our GMC Motorhomes, although some owners may have since changed to another brand of carburetor or to fuel injection. The Rochester Quadrajet has a fuel filter located inside a metal housing on the front of the carburetor. This fuel filter keeps rust and debris from our fuel tanks from entering the delicate carburetor assembly. The best time to replace the fuel filter is at home, on a cool engine, as part of an annual maintenance. Best practice would be to carry at least two spare filters in case of an on-the-road clogged filter. Symptoms of a clogged filter are an engine that will idle fine and drive slowly, but runs out of power at higher speeds or when accelerating. Removing the Fuel Filter Start by removing the air filter and air filter housing (see Winter 2022 GMC Vintage RVing magazine for more information). Now we can see the carburetor fuel filter housing protruding from the front of the carburetor. The engine fuel pump delivers fuel into this

housing where it is filtered and then passed into the fuel bowl inside the carburetor. To replace this fuel filter we will only need a couple of tools and a little patience.

Quadrajet fuel filter housing

One nice tool for GMC engine work is a piece of lumber that stretches across the engine compartment from left to right. Some call this a “belly board” because that is where your belly rests while working over the engine. It is a handy device that gives a little more comfort than you might have otherwise. Also, disposable work gloves will keep hands clean of gasoline. If you have installed a battery disconnect switch (see Fall 2021 issue of GMC Vintage RVing magazine for more information), this is a good time to use it to disconnect the battery and eliminate the chance of a spark

igniting any gasoline. Also, remove the keys from the ignition and stow them in a safe place to ensure that no one attempts to start the engine while the fuel line is disconnected – this would spray gasoline in the engine bay. We will need two wrenches. The first wrench is used to hold the carburetor fuel filter housing in place while the second wrench is used to loosen the fuel supply line. The first wrench can be an adjustable wrench as long as it can open up to one inch wide to fit the housing. The second wrench, for the fuel supply line, is a 5/8” “line wrench” or “flare nut wrench”. It is a slightly different shape than a normal wrench and it can be acquired at the auto parts or tool supply store. This will grip the fuel line better than standard wrenches, which tend to slip off under pressure and lead to busted knuckles.

Once the fuel supply line is out, use the adjustable wrench to remove the fuel filter housing from the carburetor body by turning the wrench in the direction of the passenger side. Once loose, you can unscrew the housing by hand. Inside the housing are three items: the fuel filter, the spring, and the gasket ring. The new fuel filter is a WIX 33048 or 33052, either will work (do not forget to purchase a couple of spares at the same time). Make sure the gasket ring is on the end of the housing threads – no pipe sealant or tape is needed. If the spring or the gasket ring is missing, they can be ordered from a GMCMH vendor (see page 21) or an online Quadrajet source.

wrench that measures about 6 inches long is a good tool as its short length helps prevent overtightening. After tightening the filter housing, it is time to reinstall the fuel supply line. The special “line wrench” will be needed again. The flared fitting is self-sealing and does not require pipe sealant or tape, and none should be used. Hand-start the fitting into the front of the filter housing. This fitting can be difficult to get started because the engine thermostat is in the way. If you can not get it started you may want to remove the four carburetor hold-down bolts with a 1/2” wrench or socket. This will allow the carburetor to be lifted enough to start the fuel supply line threads. Once the threads are started by hand, you can reinstall the carburetor hold-down bolts. As you tighten the fuel supply line with the line wrench, use the adjustable wrench to keep the filter housing from moving. This time, we’ll have the adjustable wrench in our right hand and the line wrench in the left.

5/8” Line wrench/flare nut wrench, 1” wide adjustable wrench

Hold the adjustable wrench with your left hand to keep the housing from moving, and use your right hand to loosen the flare nut on the fuel supply line. Rotate the flare nut wrench toward the passenger side of the vehicle to loosen the threads. Expect a small amount of gasoline to spill as the line is unscrewed.

Hold the filter housing with left wrench, loosen flare nut with right wrench

Filter housing, gasket ring, fuel filter, spring, and carburetor body

When reassembling the fuel filter housing, note that the closed, metal end of the fuel filter points toward the rear of the coach, and the open, rubber end goes toward the front of the coach. Hand thread the housing onto the carburetor body and tighten with the adjustable wrench. Do not overtighten this fitting as the soft threads of the carburetor body can easily be damaged. An adjustable

Reconnect the battery, start the engine, and inspect for fuel line leaks. If everything looks good, we can reinstall the air filter housing, remove the belly board, and set the hatch back in place. Stow the two wrenches and spare filters in the GMC for the next filter swap. Now it is time to update your log book and pat yourself on the back for doing your own work, by the book, with the right tools.

GMC Motorhome Stock Electrical Panel Kenneth Smith | 1977 Birchaven | Columbia, Pennsylvania

Recently, I had a GMC Motorhome come in with the owner telling me that he had some electrical problems with the 110 volt power in his coach.

removed and replaced with a lug located at the red arrow. All the neutral (white) wires were then bundled together and inserted into one side of the lug, which is only rated for one wire. The other side of the lug was then connected to the incoming neutral wire from the power cord.

Photos #4 and #5 show the damaged combination “Main and two circuit breaker. There has been some serious overheating in this panel.

As a retired electrician, what I found was very disturbing. Someone had made some poor modifications to the electrical panel and had ignored the obvious warning signs that there were serious problems with the system. It is very fortunate that another coach was not lost to a fire or someone hurt.

It is very rare that a neutral bar goes bad and is usually an indication of a loose connection. The correct way to repair this is to replace the neutral bar which would not cost more than what was done here. Photo #1 shows the stock electrical panel as it came from the GMC factory. The blue arrow on the left bottom points to the neutral bar. The green arrow, middle right, is pointing to the ground bar. The yellow arrow points the two-piece wire nut that was commonly used at the time our coaches were built. This is the correct way to connect multiple circuits to one breaker as the breaker terminals are only rated for one connected wire. Note how bright all the terminals are. Photo #2 is of the panel in the coach after I had removed the interior. The yellow arrow indicates where the neutral bar has been

The burnt debris on the bottom of the panel was also a warning sign that there was a problem Also, note the improperly stripped gray UF wire going across the center of the panel. Photo #3 is of the burnt busbar after the breakers have been removed. Here we have one side of the contact “stabs” completely burnt off (red arrow) and discoloration of the terminal on the right. Two warning signs here. A loose connection or overload caused the heat discoloration and there has been moisture in the panel at some time.

What can I do to avoid these kind of problems?

1. When connecting to shore power, check both the cord end and the receptacle that you are connecting to making sure that neither are damaged in any way. It needs to be a tight connection. It is best to not connect under load if you can avoid it. If using an adaptor to plug your coach into a lower amperage receptacle, be aware that you only have the rating of that source and with the added voltage drop everything is going to run warmer.

Photo #6 is more of the same damage to the single pole breaker. In this case, I had an extra panel interior in excellent shape that I could just replace the interior in the panel. If I would not have had that, I would have installed a Square D Homeline main lug panel as a replacement per NEC regulations. How do I know if I have a problem with the electrical panel? Some of the signs would be flashing or dim lights, smelling something warm/ hot in the area of the panel, loss of power in all or some areas of the coach, or even breakers tripping often. If you find any of these problems, they need to be addressed immediately. If you are not experienced with working with the electrical panels, call a professional. This is not the place for “hack” jobs.

2. A yearly inspection of the panel is always a good idea. With the power cord locked into the storage locker, so no one can plug it in, remove the panel cover and make a visual inspection of the interior. The breakers should all fit tightly onto the stabs and there should be no discoloration of the terminals. I also take a screwdriver and make sure each terminal is tight, then pull on the individual wire. (Snug, then tug). The screws can easily be overtightened, so need to be careful there. 3. Clean the air filters on the AC units regularly. They draw more amperage when blocked and create more heat

Final Drive Considerations Matt Colie | 1973 Glacier | Belleville, Michigan

The 3.07 that was the original final drive in our coaches was wrong when they were built, but all the testing was done before the first Arab Oil Embargo. Speed limits were at least 70 everywhere and fuel cost was not a major issue. Then came 55 and all that went out the window. Even at 70, the 3.07 is a little low and GM knew that, but by the time they came up with the 3.42 number, nobody was interested.

and have to downshift for every little hill. This works well for us too.

peak, but for engines like ours, that will not be any big issue.

First thing you have to wrap your thoughts around is that a typical passenger car has a road load of about 10~12 hp. I do not have numbers but from decades of vehicle testing I would have to guess that the coach road load for 60~70 mph to be up there in the 30 hp region.

Now, we go back to the input side. I have to shift gears here because in engine labs we do not have vacuum, we have manifold pressure. The two are inverse. I will try not to confuse these.

Many people have been stuck for years with the long-standing preconceived misconception that running an engine slower is always better. Better in terms of both fuel consumption and engine life. Well, both are wrong and for pretty much the same reasons.

If you start with a ~3K# passenger car, having a ~100 hp engine, you have a very different situation than we do with a 10~12K# coach having a 250+hp engine. Though that may sound equitable, you forgot the 30 hp road load we still have to manage. If that passcar engine is running below its torque peak, who cares? Just bump the throttle a little. If my coach is dragging on the hill and I bump the throttle, two things are happening. First is that the BMEP is going to climb putting more load on all the wearing parts. Then, the carburetor will probably move into the power enrichment part of its operation. There goes the fuel economy!

Even as little as 50-years-ago in my engineengineering classes, we were taught two wrong things. One was that Piston-Miles traveled was everything that mattered and a conventional carburetor was amass-flow device and so not subject to density issues. Well, both of those were wrong.

At that time, piston miles traveled was the primary engine wear determiner. Consumer Ok, so what is the loss for spinning the Reports in their car data at ibe time crank faster? Pumping losses. An internal published the N/V (that amounts to turns combustion engine is just an air pump that per mile). Well, I hope to convince burns fuel. As it happens, the torque you that this is just wrong. A peak is closely associated with the great deal of the engine wear peak volumetric efficiency (VE). Almost a quote is from internal friction. When you spin it faster or from Soichiro Honda – Most of that friction is slower, (with a fixed camshaft) I cannot find this directly related to the that efficiency goes down.

Whatever your fuel delivery control is, you want to deliver the minimum amount of fuel to create the horsepower you want. While the vacuum is high, there is not much charge in the cylinder, so not much heat is created even though the leaner mixtures burn hotter. Economy-wise, this is all in your favor. But, when the vacuum gets lower and you have more charge in the cylinder that heat can be damaging, so the fuel system richens the mixture to keep the temperature in check. As backward as this may seem to some, you would want to make road load horsepower with the vacuum as high as possible. That means that the engine is doing less work and making less friction all the way through the driveline. That is a Win-Win for you. Let’s take a minute to look at carburetors. This piece of nineteenth-century technology survives even to this day because it is relatively simple and inexpensive to manufacture. It has been displaced because it is not known for its overall accuracy. Everything it does is a compromise. So, if you change air density, the calibration will probably not be ideal. Why does this matter in this discussion? Because the less manifold vacuum that the carburetor is seeing is also the most varying mass flow. That varying mass air flow means that the carburetor calibration will have a much harder time metering the fuel input. I would like to go into this more completely, but just to explain it adequately requires more time and mathematics than I have patience for right now. Suffice it to say that the steadier air flow of the higher vacuum will give better results. If there is some part of this article where I lost you, please contact me and we can discuss further.
