president’s corner

Greetings!

I feel honored to have been elected as the President of GMCMI. Thank you for your trust. My predecessor, Dolph Santorine, provided leadership during a difficult period for all of us, and I thank him for his guidance. In case some of you do not know who I am, if you have ever attended a Convention, I am the “hat lady” that hangs out in the kitchen! I hope that I can do my best to fulfill the duties of the position with professionalism, enthusiasm, and lots of laughs!

I heard that the Lebanon Convention was a wonderful experience for all, despite some quirks, sessions were informative, there was great food, and lots of activities for all. I wish we could have shared that time with you.

Looking forward to the Spring Convention in Hattiesburg, Mississippi, from April 27-May 3, and hope to see many of you there. It will be our first time in this area and there will be many sights for us to explore either before or after the Convention.

A new board of directors was elected at the membership meeting in Lebanon and we look forward to continue moving GMCMI on the path established. We want to continue sharing our ideas, and enjoying the spirit and camaraderie that comes with owning a “one of a kind” machine! Our thanks to Margie McLaughlin, David Blackshear, Randy Van Winkle, and John Pryzbylek for their service. You can learn more about the new board in this edition of the magazine. As a past board member I felt there is too much time in between face-to-face meetings so to keep all engaged, the board will be meeting via zoom in January and July.

Your GMCMI renewal membership looked different using one of the three tiers that was unanimously approved at the Fall Membership Meeting. You will find a complete description of your choices on page 10. Your renewals are vital to the health of our organization and we need to do whatever we can to prevent shrinking of the membership and we ask you to encourage any of your friends who have not renewed to do so. Having been actively involved since our Pueblo Colorado Convention, I have noticed that most of our attendees were retirees and we need to find a way to continue having a successful Convention and meet the needs of the younger folks who have fallen in love with these machines.

My experiences as the “pilot” in our GMC will certainly be different than others. One thing of interest is that we have traveled many miles across the South as “snowbirds” and we never listen to the radio – we travel in absolute silence, just so we can hear how the engine is running! ;-) I have gotten pretty good at detecting when something is not right. So I am not sure how much technical information I can share, but I can share how much fun we have had over the years, the experiences we have had at car shows, sharing time with with members of other chapters/clubs as well as our own local rallies.

I hope as we move forward into 2023, that you will join me in meeting the challenges that are presented to us as we move forward. Please feel free to contact your VP representative for your area, or any other member of the board, officers, or VP of Administration if you have questions, concerns, or suggestions to help us meet these challenges.

Continue to enjoy life’s adventures! Travel safely, stay healthy, and hope to meet you in Hattiesburg!

The Hat that Started it All...

We were at the Pueblo GMCMI Convention and I started making coffee with Willard Murdoch and Frank Jenkins. I found folks were not quite awake when they came in and were not interested in talking. I wore this hat whenever I rode my bike to the kitchen or to the sessions and folks commented on the propellor spinning so fast! The attendees seemed to smile a little whenever they came to get coffee, so that’s were I got the idea to see if I couldn’t bring a few smiles to folks.

Lucy Weidner

“Continue to enjoy life’s adventures!”

– LUCY WEIDNER, GMCMI PRESIDENT

40 Years In The Making

In celebration of the 35th Anniversary of GMCMI, our editor Janet Frey interviewed Ralph Luby, its founder. He provided some interesting insights into the adventure that became GMC Motorhomes International. We invite you to discover how GMCMI began and discover the many milestones in the GMCMI past in the “35 Years In The Making” article in the Fall 2017 issue of GMC Vintage RVing magazine.

Below we have continued the GMCMI Timeline...

GMCMI offers a new resource for “Everything GMC Motorhome!”

There you will find GMC Motorhome merchandise, apparel, plus back issues of the award-winning GMC Vintage RVing magazine.

At the 2019 Fall GMCMI Membership Meeting, members present voted yes on the following: Shall GMCMI eliminate the requirement to be a FMCA member to be a member of GMCMI?

An electronic/paper ballot was distributed and the members overwhelmingly agreed to drop the FMCA requirement.

New ByLaws and Standing Rules were proposed and accepted December 31, 2019.

In 2020, GMCMI celebrated our 9,000th GMCMI member, William (Willie) and Julia Colón.

It was with great disappointment that GMCMI decided to cancel the Spring GMCMI Convention in Patterson, Louisiana and the Fall GMCMI Convention in Rapid City, South Dakota.

GMCMI was pleased to assist Billy Massey in the production, printing, and first mailing of the “Black List” for use by the GMC Motorhome Community.

Conventions Are Back!

The Fall “Welcome Back Convention” in Chippewa Falls, Wisconsin was a resounding success. We were all happy that we were free to move around the country again and hoping our Canadian friends will be with us at upcoming events.

A “New Life” for a GMC Motorhome

BY JANET FREY | PREVIOUS 1976 PALM BEACH OWNER | MILFORD SQUARE, PENNSYLVANIA

Our managing editor recently alerted me to a new and innovative use of a GMC Motorhome, and asked me to interview its people. So, I called Melanie and had a fascinating conversation about an Airbnb location. Five years ago, Melanie and Justin decided to pursue an idea to move up from tent camping to a small motorhome. They were searching for an Airstream, but fate led them to a 1974 yellow GMC. Located only an hour away in the middle of Tennessee, they took a ride, looked it over, and decided to drive it home. After all, they were told, it ran fine. Unfortunately, on the way home, the engine blew. After the seller tried to help and it was towed to a shop, they discovered that it would be a challenge to get it fixed. Finally, it was towed to their 5 1/2 acres in the historic Leiper’s Fork area outside of Nashville, Tennessee. After considering several options, they sketched plans to build an Airbnb destination using the GMC as its centerpiece along with colorful outside lounging and a barbecuing area. They checked with some builders and found one between projects who was willing to do the build. You can see from the pictures that it was an inspiring idea and ended up being quite charming.

BEFORE...

The GMC had been in the process of a remodel and had already been painted white inside, but Melanie decided to search for ideas to make it a true vintage atmosphere.

She found fabrics, wallpaper, and even shag carpet from Home Depot! She wanted a vintage vibe, and I think you can see from the pictures that she was very successful!

They added some practical effects such as an outside shower that offered a private solution to the wet bath in the motorhome (the indoor shower is not used). Plus, they provided updated amenities such as a programmable heater, Wi-Fi, USB ports, and a smart television that shows vintage commercials of the GMC Motorhome.

A notebook with ads and information provides visitors with a historical trip down memory lane. So, for the last four years, the GMC known as the “Quirky Canary” has been a popular destination for older folks who remember the days of the GMC, and younger folks who have no idea what it is, but love the larger van/smaller motorhome and its salute to the past.

The site is rented all season by people from all over the United States, China, England, and Australia. It is usually booked six weeks in advance, and is closed from November 15 to March 15. Melanie says that if you have questions, you can message her through Airbnb or Instagram (@quirkycanary).

What a great and creative use of our beloved GMC Motorhome!

L-R: Melanie, Vivienne, Justin, and Davis.

GMCMI Welcome Pack

Absolutely Blown Away

Chris Ritter | 1976 Eleganza II | Bethel, Pennsylvania

I just received my GMCMI welcome pack and the flashdrive I ordered. I am absolutely blown away by the amount of information on the flashdrive and the high quality magazine that GMCMI publishes. The Parts Interchange publication is easily worth the cost of membership alone.

I am the Library Director at the AACA Library (Antique Automobile Club of America) in Hershey, Pennsylvania and I see A LOT –several dozen – different automotive club publications each month. For what it is worth, the GMCMI magazine is better than nearly all of them! I have shared your welcome letter/pages with our CEO as I think we can learn a bit from the way you market your organization to new members.

Jared Kohl Vice President Eastern

Jared Kohl lives in beautiful Rappahannock County, Virginia with his wife of 24 years Stefanie who he credits/blames for getting them into the GMC lifestyle in 2012. While searching for motorhomes in 2012, these GMCs kept coming up in the searches. Stefanie thought they were so cool. Jared of course looked at her sideways and said “40-yearold motorhomes? Are you nuts?” And here they are now traveling in one nearly 50-years-old.

They currently own two GMCs (1973 and 1975) and use both interchangeably and take their four excellent traveling rescue beagles with them everywhere they go. They have traveled as far north as Montreal, as far west as Yellowstone and as far south as Florida in their

GMCs. They have also benefited from the incredible GMC Community for assistance on some of those long trips. Specifically in New York when Bill Bryant assisted them as brand-new GMC owners and then again in Iowa when they needed a transmission and Bob Dunahugh came through with a replacement for them. The GMC Community is amazing.

Jared also serves as President of the GMC Tidewater Crabs (Virginia, Maryland, and West Virginia) and that group tries to hold monthly rallies throughout the camping season. Jared and Stefanie are heavily involved in their church and local community organizations. They met while attending Brigham Young University in Provo, Utah.

Jared is an Eagle Scout and served a two-year church mission to Ukraine in the mid-90s. Jared’s day job is as Vice President of Technical Operations for an IT Consulting firm in Falls Church, Virginia. Stefanie is a Park Ranger at Shenandoah National Park and a Home Health Physical Therapist Assistant.

Kim Carter Vice President Midwest

Kim and her husband, Dennis, live in Lewistown, Illinois with their ‘pibble’ furkids, Gwin and Augie. They acquired their 1977 Palm Beach in 2016 to travel with their furkids, meeting followers of the pups’ Facebook page. The GMC Motorhome was perfect for their needs and the bonus was discovering the Community of GMCers through GMCMI and their local club, GMC Six Wheeler Motorhome Club. Kim has served as the Six Wheeler’s president for the last three years.

Kim and Dennis attended their first GMCMI in Shawnee, Oklahoma spring of 2017. Since then they have attended six more! They enjoy learning about their coach and have met outstanding people from across the US and as far away as Australia! The core interest in GMC Motorhomes creates a bridge to forge lasting friendships! Kim is honored to begin serving on the board of such a great organization!

Kim and Dennis have two grown children, Scott who lives with his family in Washington, Illinois and Leslie who lives with her family in England. They have one grandson, Jackson, and four step grandchildren, Morgan, Grant, Evey, and Mae.

Kim is a retired RN specializing in emergency, trauma, and prehospital care. She worked in occupational medicine as a project manager, and public access AED and EMS coordinator for a global manufacturing corporation and served on her volunteer fire department for several years primarily with EMS response and providing continued education. Kim has taught CPR for 30+ years and currently is certified as an AHA instructor.

Sonya Null Vice President Great Lakes

Sonya and her husband Terry are from Indiana and joined GMCMI in 2017 after purchasing their first GMC in 2016. They attended their first GMCMI Convention in 2017 and have attended five thus far. She is looking forward to retiring and traveling extensively, but until then continues to work full time as a CPA providing outsourced accounting services.

Prior to purchasing their 1976 Palm Beach GMC, Sonya and Terry camped in a variety of RVs, starting with a popup, moving up to a travel trailer and then to a Class C S.O.B. (some other brand). They were not actively looking for another motorhome, but after an introduction to the

GMC coaches through Terry’s work, and a group of friendly GMCers at an open house during a local FMCA rally, their plans changed and they bought the Palm Beach. Sonya and Terry camp locally on weekends through the year, and as vacation schedules allow travel a bit farther a few weeks a year. Prior to purchasing their GMC, they traveled to both the east and west coasts and look forward to comparably long road trips in the GMC. The farthest trip the GMC thus far has been to the Florida Keys; however, most trips have been within a day’s drive.

When not traveling, Sonya enjoys spending her free time doing outdoor activities, including hiking, kayaking, and paddleboarding, as her day job keeps her indoors. She and Terry enjoy dirt bike riding in the trails of Michigan and taking road trips on their Harley-Davidsons.

Ty Hardiman Vice President South Central

Ty grew up in a small town in Oklahoma, where he developed an interest in mechanic work at a young age while helping his father work on the family’s airplanes, boats, motorcycles, and cars. Also as a child he developed a love for motorhomes and the outdoors inspired by his mother and her childhood experiences camping in a converted International school bus during the 1950s.

All of these interests merged in a nearly perfect manner when he bought his first GMC Motorhome. This gave an opportunity for Ty and his parents to plan new camping trips together, whether to the Rocky Mountains or to GMCMI Conventions. Ty’s primary coach is a 26’ 1977 Kingsley. It was a California coach that had accompanied its original owner to to Vail, Colorado where Ty found it. He flew to Denver, took a ski shuttle to Vail, and spent the day evaluating and purchasing the coach. He immediately encountered his first GMC adventure navigating the Vail Pass and Eisenhower Tunnel on the return trip to Oklahoma. Fortunately, the Kingsley completed the trip without complaint!

Ty attended his first GMCMI Convention before purchasing a GMC. His positive experiences at the Convention and with the online GMC Community helped confirm his decision to become a “TZE” owner. He is a member of the GMC Classics and the GMC Flatlanders.

He currently lives in Norman, Oklahoma where he spends his time working on classic cars and motorcycles. Ty enjoys learning from other mechanics and GMC owners; he is also dedicated to mentoring and teaching classes at GMCMI Conventions to ensure knowledge is passed on to future generations.

The Freys Share Memories

BY JANET

Ken and I never thought about “camping” until our daughter Sue was invited to the Beacon Lodge Camp for the Blind in 1983. The Lions Club was determined that she should have the camping experience, but the camp was four hours from our house and she was only eight-years-old. Ken decided that we should get a motorhome so that we could take her to the camp, stay at a campground overnight to be sure she was settled in, and then head home.

Our first RV was a 1976 Tech, a boxy Class C that had been around the block several times! Our daughter’s bed over the cab was perfect until she became taller and hit her head on the roof. Time to make a change and we ended up changing our lives forever. During a “cabin fever” sale at a nearby U-Haul dealer, we found a 1976 Palm Beach GMC Motorhome. Ken was aware of the GMCs, but this one really caught his eye. I was fascinated by the floor plan and knew that it would provide living areas for all of us. So, we traded our Tech, bought the GMC Motorhome, and started going over it inchby-inch. Ken was a former Oldsmobile dealer mechanic and

was familiar with the Toronado components. The motorhome was a learning experience, though, and he worked his way through all the systems.

We joined a local GMC club, the Colonial Travelers, and then GMCMI. It did not take long for Ken to realize that there was a niche for GMC maintenance and repair that would fit nicely in his business, Ken Frey Auto Repair. Our first GMCMI Convention was in Gettysburg, Pennsylvania, but we were only able to attend for a few days.

However, in September 1993, we attended the Convention in Goshen, Indiana. It was quite an experience, and we had our first encounter with the Convention activities, especially seminars and “Show ’n Tell”. Our neighbor, Clarence “Marty” Martin, was soon a good friend, as were many of the attendees. Ken introduced himself as a vendor and service provider and did some installations of his extended transmission dipstick tube. I helped, too, and soon

became known as “Mrs. Dipstick”. Thankfully, that changed as we became involved with many of the activities of the Convention.

Ken became known for his cooking skills as well as his knowledge of the GMC. Over the years, we have attended about 30 Conventions, putting many miles on the GMC, and making many, many friends. It has been quite an adventure traveling around the country, exploring new areas, and especially meeting the GMCers and their coaches.

As I went through my many photo albums last winter, scanning and saving photos, I was reminded of the fun times with Sheriff Larry McLaughlin, the womenless weddings and fashion shows, the wonderful crafts, fun entertainment, and the GMCs themselves, always shining during the open house tours. Family members always were mystified by our “motorhome conventions”, wondering what DID we do at those things? We enjoy everyone who attends GMCMI Conventions.” The wonderful people who provide their time and support are the mainstay of the clubs/ chapters, GMCMI Conventions, and the GMC Community.”

In 2020, we decided to make a change. Ken was going to retire, sell the business and property, and we would soon have no place to service the GMC. So we sold it and it is now living in New Orleans. But we continue to travel and support GMCMI, now using our 2018 Coachmen RV S.O.B. (some other brand). Ken will continue to be a resource of information and parts, and support GMCMI with his knowledge and cooking. I have been the GMCMI Secretary for several years, and hope to continue as we both anticipate attending many more Conventions in the future.

What a 40th

BY JANET FREY | PREVIOUS 1976 PALM BEACH OWNER | MILFORD

PENNSYLVANIA

TThe venue was the James E. Ward Agricultural Center, which was a very busy place! There were sheep and POW WOW at the beginning, dogs (many, many dogs!) leaping into pools most of the week, wrestling, and a rodeo.

Convention Numbers ...

111

Is the number of registrations; 4 were partial attendees, 19 first timers, 6 off-site, and 11 additional day passes. With 81 GMC Motorhomes!

22.25

Is the number of hours of technical sessions, plus four clinics: Rebuilding a 455 Engine Demonstration, Weighing of the Coaches, Headlights Alignment, and Updating Your GMCMI Flashdrive.

16.5

Is the number of hours of non-technical sessions, plus crafts, treasure hunt, and a Ladies Luncheon hosted by the Ladies of the GMC Dixielanders.

Many members commented on the beautiful scenery of Tennessee as they traveled here, and the weather was almost 100% perfect. The new format allowed members and regional groups to gather in the evening for pot-lucks or adventures at the many local restaurants. We started with a relaxing firsttimers meeting and ice cream social, followed by Bingo.

Tuesday offered a catered breakfast and a Welcome Meeting where charter member Bill Helmore was honored and then it was time to start the sessions. We got acquainted, learned about tech issues and solutions, did the hula and crafts.

Thursday morning we had the opportunity to “Meet the Motorhome Sales Development Manager Al Walker from the GMC Factory in

Pontiac, Michigan. There were many tidbits of interest and he donated a special GMC Jacket with GMC sponsored rally patches for the silent auction.

A fascinating tech clinic was offered by Barry Owen as he spent the week rebuilding a 455 engine! He started it on Saturday morning, much to the delight of a large, curious audience.

Many volunteers helped the members enjoy the location as well as each other. The venue had presented some logistic problems, but we all worked together to overcome them and succeeded as a group to be our friendly, competent selves.

A gem at this location was Fiddler’s Grove, a wonderful grouping of historic buildings assembled into a small village. On Friday,

the Convention attendees were offered exclusive access and were treated to intriguing stories from the many guides. The weather was beautiful, the people friendly, and what more could we do than have Outhouse Races?? Teams were assembled, our announcer Scott Adams helped the excitement build, and then it was time! The racers and throne sitters charged up the hill to the toilet seat targets, rolls were thrown, and then back to the start. Champions were crowned, and all had a great time.

We gathered at our building for a delicious catered dinner, and then members boogied the night away with line dancing and karaoke.

It was a busy week packed with food (I forgot to mention the eggs, S.O.S., Petros – chili, ice cream, breakfasts, Ladies Luncheon, and the regional gettogethers), and the informative, interesting, and fun sessions. It was a joyous way to celebrate 40 years of GMCMI!

Technical Corner

Technical Sessions & Clinics at 2021 Fall GMCMI Convention

• The do-it-yourself owner/mechanic (“Mechanicing is mostly the thinking rather than the doing!”)

• Coach knowledge and repair

• Maintaining log files

• Lifting the coach/jacking points

• And much more…

The technical program is the flagship of GMC Motorhomes International. The topics are developed and presented by owners and enthusiasts to merit your confidence. These presentation summaries serve as a review for those in attendance and are designed to inspire others to attend conventions and experience in person the ambiance of the presentations.

>> GMC 101: Maintenance for New Owners | Ty

Hardiman

Ty continued his presentations to new and prospective owners of the GMC Motorhome in Lebanon. He emphasizes in his presentations the importance of attention to detail on the maintenance of many aspects of the vehicle. Some of those he addressed in Lebanon included:

• The history of the coach

• Reliability of the coach

• Roadside incidents and towing services

See an article by Ty on page 24, on a couple of the topics he addressed in his presentations.

>> Pitfalls of New GMC Motorhome Ownership | (sub-titled “Horror Stories That Do Not Need to Happen to You) | Ty Hardiman and Jim Kanomata Among the topics addressed were:

• Exhaust manifold bolt torquing –and proper sequence

• Hydraulic windshield wipers and filter maintenance

• Mufflers – (buy only top quality…)

• Drive axle flange torquing (vital to maintain careful surveillance)

• Automatic Transmission shift cable: it is often the cause of erratic shifting!

• And much more…

>> GMC Braking Issues and Solutions | Dave Lenzi

Dave is a frequent presenter on this topic at GMCMI Conventions. In Lebanon, this was an encore presentation of prior similar ones. Many audience members hear and see something that did not “soak in” the last time they attended one of his sessions. He states that his objective is to acquaint owners with the

vacuum brake booster, master cylinder, and combination valve on the coaches. He addresses common problems with low brake pedal, excessive pedal effort, and vacuum leaks. A key feature of his presentations is a test stand to show the operation and problems with the brake system. He demonstrated the pedal effort required for operation of the brake system for various levels of vacuum at the booster. Images of close-up work were projected onto a large screen for the convenience of the audience.

>> What I Am Seeing as Miles and Age Advance on Our Coaches

| Jim Kanomata

Jim had a long list of topics to cover in his presentation. Here are a few that he addressed:

• Radiator and Coolant Surveillance (Either change the coolant as recommended by coolant mfr. or test quality at regular intervals with test strips or volt-ohmmeter method)

• Use only radiator cap rated at 9 PSI.

• Confirm proper fan clutch performance (i.e., approximate engage and disengage temperatures)

• Oil cooler hoses – examine at each oil change for deterioration and need for replacement.

• Monitor condition of brake fluid and change (or top-off) as needed.

• Muffler heat shields – ensure that they are in place!

• Drive axle boots – maintain careful

observance of them and change at first sign of deterioration/grease leakage.

• Laser thermometer – always carry one and use it! (for checking tire, bearing, temps, etc.)

• And much more…

>> A Bad Frame Is

Not A Death

Threat for A GMC | Barry Owen, Don Fenwick, and Bob Hughson

The presenters addressed the challenges and how they overcame them by replacing the badly deteriorated frame of the 34’ “stretch” GMC owned by Don and Bob. They described the condition of the OEM frame with many pictures; it was at great risk of a catastrophic failure. They described the suspension of the coach for the replacement frame. The replacement frame was much stronger than the original as it was a boxed rail rather than the OEM “C” channel design. There was much audience participation – and interest – in this presentation. The presenters interspersed humor in their presentation, much to the delight of the audience.

>> Hydra Boost | Bob Stone

Bob continued his presentations at GMCMI Conventions on the merits of hydra boost braking. He showed some of the hardware components of the braking system and described the much-improved performance of hydra boost braking relative to the OEM vacuum-assisted braking. He described the brake fluid volumes and pressures required to safely stop the GMC Motorhome. He described extensive testing,

using several master cylinders activated by a Hydro-boost brake assist, and the results. The end components consisted of 70 and 80MM front calipers and the hydraulic rear brake cylinders. He provided results of the testing and recommendations for achieving the optimum brake fluid volumes and pressures for the calipers and cylinders.

>> What’s Your GMC Motorhome Question? OR: “Two Deaf Old Codgers Asking Questions” | Ken Frey and Lou Boone Ken and Lou bring a lot of experience and knowledge to the GMC Motorhome Community. GMCMI was pleased to offer this session allowing Ken and Lou to share their expertise with attendees at the Convention. Questions ranged from “How does the two tank system and venting work?” to “How does the Motorhome go straight down the road?”. Discussions touched on balancing wheels with traditional weights and with material such as equal put into the tire for balancing. Vapor lock seems to always be a hot topic – being hot is one of the reasons it

Attendee Comment

is a topic. The discussion touched on several approaches to minimize vapor lock issues.

>> Exterior Maintenance and Repairs | Mike Sadlon

The focus of this presentation was on the care and maintenance of the fiberglass construction of the motorhome. Mike advised to hire a professional for fiberglass repair for best results. For sealing leaks, he recommended “Cool Seal #5200 (but consult local paint store as there may be preferred alternatives in some locales). The cost for materials alone for painting a GMC Motorhome is now as much as $5K. He cautioned that paint stripper should never be used on the fiberglass construction of the coach.

>> New 1-Ton Front Suspension | Rick Michelhaugh and Barry Owen

Much more than expected. Everyone was willing to share their knowledge and experiences. member for two years, first Convention

Presenters described the installation of a modern 1-ton Chevy suspension onto a GMC Motorhome chassis. A 2018 Chevy pickup truck was selected as the donor vehicle primarily because it is a heavy duty pickup that has independent front suspension. It has a similar torsion bar design to the original GMC Motorhome suspension. They highlighted several advantages of the installation including bearing service and larger brakes but acknowledged disadvantages including cost (as much as $7,000), different wheel/bolt pattern, larger wheel/tire diameter (32.1” vs 29.5’).

New Technical Session Offered Ladies, Do You Have a Function/Mechanical Question About the GMC Motorhome?

BY CONVENTION MANAGER KIM WEEKS | 1973 CANYON LANDS | INDIANOLA, IOWA

Personally, I would like to have the opportunity to learn more about the mechanics of the GMC Motorhome but not feeling uncomfortable, like I am asking a “dumb” question....an idea emerged. Why not ask Ty Hardiman the author of the “GMC 101: Maintenance for New

Owners” column and tech presenter to conduct a session for those who do not plan on becoming “the main mechanic” for their motorhome. The title may be a bit sexist, but the comments overwhelmingly asked to continue having this session and allow more time!

>> Options for Fuel Injection in a GMC Motorhome

When GMC owners start talking fuel injection the question of which system should be installed on their motorhome always comes up? Unfortunately, there is not one answer to this question because there are many choices and everyone has a different opinion. This session was designed to provide in-depth information on each of the 4 systems that are most popular within the GMC Community. These systems are the 80s & 90s GM Throttle Body (TB) with the EBL upgrade, FiTech, Holley Sniper, and MSD Atomic. Randy explained the features of each system and presented the pros and cons so that those considering converting to an Electronic Fuel Injection System have the necessary information to make an informed decision. Additional areas of discussion included what kind of Spark Control is provided, how can each system be monitored, how is fuel delivery handled, how

Attendee Comment

tuning works with each system, are adapter plates needed for the system, and how support works for each system as well as part availability and procurement. This was the first session in a series of 3. The next session addresses how to install these systems and the third covers a deep dive into how these systems deliver the correct fuel mixture, how the different systems self-tune, and how to approach more detailed tuning that most will require.

>> Installing Electronic Fuel Injection on the GMC Motorhome

This is the second session in the series for this Convention and covers the common installation issues with each of the covered systems. Randy has extensive experience installing several EFI systems from multiple vendors. The common issues covered in this session included fuel delivery, power sources for constant +12v and ignition +12v, throttle and cruise control linkage, adapter plates, air cleaner options, return line, O2 sensor, distributor, and idle calibration.

FUEL INJECTION SESSIONS

A different approach was made on scheduling information on fuel injection and the GMC Motorhome. The original session was divided into three sessions which offered a more direct approach. Thank you Randy Van Winkle for conducting these sessions.

• Fuel delivery: Randy recommends two fuel pumps along with two fuel filters located as close to tanks as possible (intank pumps is an option). This provides a built-in backup for the pump and filter.

• Power sources: How to identify the correct sources were identified.

• Linkage: Each system has unique challenges with linkages. Approaches for getting the linkages working efficiently were discussed.

• Adapter plates: Holley Sniper does not require an adapter plate while the others must be adapted to the manifold with a plate.

• Air cleaner: The air cleaner may or may not have clearance. Discussion centered on how to fix this issue or what other options for air cleaners are available.

• Return line: While some of the aftermarket systems indicated no return line is required, Randy advocates that a return line be used in all cases. The discussion looked at how to set up and route the return line.

• O2 sensor: Discussion centered on the types of O2 sensors the different systems use and the proper clocking for the sensor.

• Distributor: Different distributor options for each system were discussed as well as options for installation.

• Idle calibration: All the discussed systems require that an idle calibration procedure be applied to insure the idle air control (IAC) is adjusted properly.

>> Fuel Injection Tuning – Deep Dive

This was a more advanced session that looked in much more detail at how these systems calculate the amount of fuel to spray for each cycle. Concepts like “open loop”, “closed loop”, power enrichment, and lean cruise were explained. Randy went into detail on how these systems utilize Volumetric Efficiency (VE) tables and how adjustments are made to these tables. All of the systems utilize VE tables in similar ways to determine the amount of fuel to spray during each cycle. The systems differ in how they automatically tune the VE tables and those approaches were discussed in this session. The next area of tuning discussed was how the systems control spark advance. Randy discussed how he determined what the most efficient degree of advance should be for the 455 and 403. The discussion also covered how lean cruise affects how much additional spark advance is needed to maintain efficiency. Bottom line, all the systems can provide the appropriate fuel mixture and automatically tune fuel ratios in real time. The different systems do differ in how they handle controlling spark advance and these differences were discussed.

Technical Clinics

>> Rebuilding a 455 Engine Demonstration | Barry Owens

Attendees at the Convention were in for a great treat as they got to watch the assembly of a 455 engine live! It takes a bit of time to assemble a 455 engine that has been machined and ready for new components so sessions were scheduled for each day of the Convention. Barry took the audience through the process of the assembly providing critical information about each step. For example, Barry explained and showed the process of installing pistons into the engine, the importance of getting the camshaft installed correctly, and how to properly lubricate the cam for the first startup.

Barry must have experienced a little apprehension as the final day approached when the engine was going to be started for the first time. The time arrived and the audience waited with bated breath as Barry completed the final preparations for the “big startup”. The moment came and the engine fired then Barry ran it up to 2000 RPMs and kept it there for about 20 minutes to ensure the cam was properly broken in. Success!

>> Headlight Alignment | Richard Waters

Thanks to Richard Waters for again providing the alignment equipment, the same type that was originally used on the GMC Motorhome, and conducting the clinic with a new assistant, Sonya Null. He has done this several times at GMCMI Conventions. Owners appreciated the opportunity to have their headlight alignment checked and adjusted if needed.

>> Weighing of the Coaches

Thanks and congratulations to Mike Sadlon and the entire team of volunteers for their service in weighing coaches at the Lebanon convention. Thanks also to Jeff Sirum for providing the scales and Mike’s guidance for the weighing of the coaches/checking ride height.

Mike reported that 25 or so coaches were weighed and ride height checked.

>> Updating GMCMI Flashdrives

A big thanks to Katie Geuin and another gentleman for volunteering at the last minute (with the assistance from Matt Colie remotely) to update the GMCMI Flashdrives for attendees.

Maintenance for New Owners

GMC 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 in GMCMI. Many parts will also be available at auto parts stores.

The Engine Cooling System Part Two

Radiator Hoses, Engine Coolant, and the Radiator Cap

In the last column, we discussed the basics of the engine cooling system and changing the engine cooling thermostat. Another critical part of the engine cooling system is the radiator hose set. This consists of two rubber hoses that allow hot coolant to be pumped out of the engine, into the radiator to be cooled down, and then back into the engine to

These hoses have a tough life carrying coolant at 195° F (90.5 C) temperatures or higher. They will last for years, but not forever. If you do not know the age of your radiator hoses then consider replacing them and recording the date in your service log book. Like many preventative maintenance projects, this is an item that is simple to perform at home, but very inconvenient to do when broken down on the side of the road.

Warning: Do not work on the engine cooling system when the engine is hot. The system contains pressurized, boiling hot liquid during engine operation, and for some time after shutdown. Let the system cool down to a safe temperature before starting work.

Draining Engine Coolant

To replace the hoses we need to drain the engine coolant. The radiator drain port, or “petcock”, is on the back side of the radiator on the driver’s side (see GMC Vintage RVing, Issue 160). Turn the petcock counter-clockwise to open the valve and allow coolant to drain into a bucket. If no coolant comes out you may have debris plugging the valve; run a piece of coat hanger wire into the hole to clear the sediment and coolant will begin to flow. A five-gallon bucket is too tall to fit under our coaches, but 10” tall painter’s buckets should fit. We will be draining close to four gallons of coolant so be sure to have enough buckets on hand. You could also use a 16 quart or larger oil change container; this will make it easy to transport waste coolant to a disposal location.

Remove the radiator cap to speed up the drain process and allow twenty minutes or longer for the system to drain out. It might occur to you that a much faster way to drain the coolant would be to

yank the lower radiator hose loose – before trying this be sure that you have a wellthought-out plan to accommodate 3 1/2 gallons of slippery green poison that will dump out of the hose within 30 seconds or so. When the system is fully drained, close the petcock valve.

Handling Engine Coolant

Our GMC Oldsmobile engines use a mix of 50% Ethylene Glycol (green) and 50% water. Auto parts stores carry pre-mixed gallons of coolant – check the label to ensure the coolant contains ethylene glycol. General Motors recommends changing the engine coolant every 24 months; if you do not know the age of your coolant this would be a great time to replace with new. Coolant can be disposed of at most places that accept used engine oil.

Ethylene glycol is deadly when swallowed by humans or animals (see GMC Vintage RVing, Issue 160). Older coolants have a sweet, sugary flavor; make sure this poison is not left in open containers where animals or children might be tempted to drink it. Modern coolants have a bitter flavor to reduce the chance of accidental poisoning. Consider using plastic sheeting, cat litter, or oil absorbent to catch drips and spills.

Helpful tools include a utility knife, a quickchange screwdriver with a 5/16” socket tip that will slip over a hose clamp screw, and a right-angle pick to help break hoses loose.

Removing the Radiator Hoses

Let’s start with the upper radiator hose first. Open the engine hatch and remove the air filter housing (GMC Vintage RVing, Issue 158). The radiator hose is connected to the engine with a hose clamp. Loosen the clamp screw with a 5/16” nut driver (preferred) or a flat-head screwdriver and slide the clamp out of the way. The hose may then wiggle off, or it may be stuck in place. A right-angle pick is an inexpensive tool that can help loosen a stuck hose. If you plan to discard the hose, feel free to cut it off with a utility knife.

Radiator Hoses

GMC vendors often stock two choices on the upper radiator hose. The original GM hose, with a straight shape, and an alternate hose, Gates 20991, with a zig-zag shape. The alternate hose may need to be trimmed to fit our application better. A common lower hose for the GMC is a Gates 22125, and trimming is required before installation. In both cases, the hoses supplied by the vendors will already be cut to size and marked to indicate the correct orientation of the hose. When trimming and installing the hoses, the primary goal is that the hoses never be allowed to come in contact with the fan blades or belts at the front of the engine.

stores. Make sure the new cap is stamped “9 lbs”. If your cap is stamped with a higher number, such as “15 lbs”, it is not correct and should not be used.

Refill & Test

Now we can fill the system – four gallons of coolant should fill the system with some left over. A funnel will be necessary to prevent spills. Each time the radiator fills up, wait five minutes and add more coolant if needed. When no more is needed you can install the radiator cap. Next, add coolant to the white plastic coolant recovery tank close by.

5/16” nut driver fits over the clamp screw. A wrench, ratchet & socket, or flathead screwdriver would also work.

The upper hose has a second clamp where it attaches to the radiator. This will be more difficult to access and will likely require a trip under the front of the coach to reach it. When the upper hose is off, go under the coach and repeat the process for the lower hose.

Do not forget to slide the metal hose clamps on before attaching the hose. You can wipe a bit of coolant around the inside of the hose to make it easier to slide on. After installing use the 5/16” nut driver or flat-head screwdriver to tighten the clamp screws. If using a wrench or ratchet, be careful to avoid over-tightening the screw as this will damage the rubber hose and shorten its lifespan. Double-check that the petcock valve is closed and we’ll be ready to start filling the system with coolant.

Radiator Caps

Radiator caps are another component that can fail over time and this would be a good opportunity to install a new one. The cap, an AC Delco RC32 or equivalent, is available from GMC vendors and auto parts

Start the engine and check for leaks at the hose clamps. If all looks good then the air cleaner housing can be reinstalled, the hatch closed, and a test drive can take place. As the coach warms up check for leaks underneath. When the engine cools down overnight, you may find that the recovery tank level has dropped below the “MIN” (or labeled “COLD”) mark. Check each time when starting the coach and be prepared to add coolant until the system eventually stabilizes.

Now we can update our service log book with the date, odometer, and parts numbers – and this one is finished. This is a relatively simple project, requires few tools, and the parts are not expensive. And the next road trip will start with a bit more peace of mind. Happy GMCing!

Silent Auction...New Equipment...Crate Revamp

BY KIM WEEKS | GMCMI CONVENTION MANAGER

Thank you to all that made our two silent auctions a success! We are happy to announce that we have replaced the large coffee pot with four 100-cup coffee pots and one new speaker system which is much smaller. We will test the speaker system at the Spring Convention and hope to replace the other two systems in the near future.

Thank you to a small group of hardy volunteers that met in Oklahoma near Ty Hardiman’s business and went through all the shipping crates, removing duplicate items, items not used for a while, etc. The group included Randy & Margie Van Winkle, Fred & Sharon Hudspeth, Richard & Jaye Hodges, Mike & Billie Kelly, Keith Weeks, Ty Hardiman, Rex & Betty Hardiman, and Dolph Santorine.

A right-angle pick is useful to loosen rubber hoses found throughout the coach.

An Electric Parking Brake (EPB) for the GMC Motorhome

Bruce Hislop | 1977 Palm Beach | Ontario, Canada

The holding power of the OEM parking brake on the GMC Motorhome was marginal from the start, and most rear disk upgrades with a parking brake did not fare much better. Add to that, the parking brake cable system was complicated and subject to corrosion. It also required careful adjustment for optimal operation. Many upgrades have been tried on the GMC with varying degrees of success.

Enter the Electric Parking Brake (EPB)

The EPB is not a new invention and have been standard equipment on higher-end automobiles for many years. Manufacturer ZF recently announced they had surpassed their 200 millionth EPB unit. The larger calipers required for the GMC Motorhome application became available when truck manufacturers started making EPB as an option.

We (Albert Branscombe and myself) have designed and successfully tested a GMC Motorhome with an EPB system holding on a 15% grade (8.5 degrees). The test bed maxed out at 8.6 degrees of inclination. Further testing is required to find the maximum holding angle.

Features and Benefits:

• Easy installation

• Self-adjusting

• Simple ON/OFF switch control with visual and optional audible alert that the EPB is ON

• No more strong-arming the lever to set the parking brake (female friendly)

• Minimal wiring with available GMC specific harness

• Off-the-shelf parts and controller

For more information contact:

Albert Branscombe branscoa@bmts.com

When I installed the 4-wheel rear disk brakes, I also added a line-lock since the calipers did not have a parking brake. I never really used the line-lock as we always parked on a level surface. But I knew not having a proper parking brake would be an issue someday and would be required for a safety check for the sale of the coach.

Albert Branscombe is the guru of the GMC Motorhome parking brake. He and I are also members of the GMC Heritage Cruisers. In conversations with Albert, he told me he was working on an Electric Parking Brake (EPB). These are becoming popular on many vehicles. The issue was to find an EPB caliper with the clamping power to hold the GMC. A controller would also be required to operate the calipers properly. A 9 (uc) commercially available controller was desired.

Albert advised me that he had found a suitable caliper and controller. He had been doing some work measuring the caliper clamp force and the current required. After some discussions about the design and operation, I agreed for my coach to be the test bed for this system.

In preparation for the installation, I ran the required power and control wires and also the caliper wiring. The system requires about 35 amps for several seconds to engage the EPB, so I ran #8 positive and negative wires from the front aluminum panel to the rear behind my fridge. This is where I planned to mount the EPB Control Module. The #8 wire is protected by a 40 amp fuse and is powered by the chassis battery terminal. The EPB switch is low current, so I ran a

CAT5 computer cable from the driver’s side panel back to behind the fridge. When Albert had the calipers and mounts ready, we met at Borrmann’s Garage to go over the installation. Of course like all of Albert’s work, they are a work of art!

Next, the existing disks and spacers were removed from the hub. The spacer sets the disk to the correct position with the caliper.

The hub must be cleaned of crud to allow the spacer and disk to fit properly. The white cap is to keep dirt out of the bearings. It is important that the hub face where the spacer matches is clean so the disk can run true.

First the old disk brake system had to be removed from the rear-rear bogies.

Also, note there is a small chamfer on the hub. A corresponding chamfer must be machined on the spacer to allow it to sit flat. A small half-round file made quick work of this issue.

Future spacers will have this chamfer already milled in place.

Once the spacer is sitting perfectly flat with the hub surface, the disk can be added and bolted into place. Albert gives the desired torque settings for these bolts.

For additional technical session presentations and papers, go to gmcmi.com/technical-presentations-papers/

further than the existing seals for clearance. From my measurements and observations, the seal was not going to interfere with the bearing.

With that measurement taken, I removed the old seals and then cleaned and repacked the bearings.

Once the old caliper bracket was removed, the mounting surfaces on the bogies were cleaned. Then the new caliper brackets were installed and the mounting bolts torqued to spec.

At this point, I had not pulled the inner seals from the hub because I wanted to check the clearance between the hub seal and the caliper mounts. I use a tool from Dave Lenzi (810-653-3902 | mlenzi@ charter.net) to set my hub seals. Turned out I needed to set the new seal in just a bit

When reinstalling the hubs, be sure to follow the “GMC Motorhome Service Manual” for the proper procedure regarding pre-load and setting the final position of the retaining nut. Below is a diagram showing the possible interference between the seal and the bearing (note that the current seals available have a different profile and can hit the bearing if the seal is not left slightly proud of the hub housing as shown below). The wheel nut assembly instructions are also shown below on the right.

While Rotating Hub Assembly:

1. Tighten nut to 25-30 lbs. ft.

2. Back off nut 1/2 turn.

3. Re-tighten nut finger tight, secure if possible.

4. If unable to secure at finger tight, back off to first securing position.

5. Rear hub must be rotated at least three revolutions of spindle nut during tightening and re-tightening operations.

6. Check dim - .001 - .005 end play between hub and spindle.

Brake pads in place. Note that, unlike my previous calipers, the pads are held in place by the caliper mount, not the actual caliper. The calipers provide only clamping action. Dave Lenzi’s mid-axle disk brake system is the same way.

Next, fill the new calipers with fluid and bleed the brakes and lines. I have Jim Hupy’s (503-362-1583 | jamesh1296@ gmail.com) excellent pressure bleeder for this job. It makes quick work of this job. I elected to do a complete brake system flush while I was at it. The old cookie sheet catches any brake fluid spills.

Time to check for leaks. First I pressed the brake pedal a couple of times to clamp down on the caliper. I then checked for leaks at the new caliper and hose connections. Then I started the engine so the brake booster will work and pressed the pedal a couple more times, then I pressed hard to get the maximum pressure. Then I checked for leaks again and none were found WOO-HOO!

I got a nice firm pedal with good height so I suspect I had some air trapped in my brake system previously.

The EPB motors can now be installed and their power wires plugged in. Be sure to follow the torque specs as their housings are plastic. I checked the wiring once again to the control module and the switch. When everything was checked, I plugged in the main power fuse for the EPB control module. Turn the ignition switch to ACCY and turn the EPB switch to ON. You should hear the EPB caliper motors run for several seconds, then stop and the EPB switch should light up to indicate the EPB is set.

Turn the switch to OFF and you will hear the caliper motor run for several seconds again to retract the calipers. The switch light will go OFF when the EPB is disabled. The switch light and the system itself only operate while the Ignition switch is in ACCY or RUN positions. The RED indicator light also has a BEEPER to remind you that the EPB is engaged.

I tested my new EPB system in an empty parking lot to check for holding power. Albert and I plan to test the EPB at Borrmann’s Garage in the near future.

Calipers are now mounted.

Frank has a large truck hoist that can be tilted front to back so we can test for holding capabilities on a grade.

Here are some photos of the system once completed. The EPB control module is mounted behind the fridge. On my coach (1977 Palm Beach), there is an external access panel so it made sense to mount it here. The use of a CAT5 cable for the control switch meant I could use a short CAT5 cable jumper and have the switch by the control module while testing.

Testing

The completed system was tested on a dual-piston rail hoist. Two digital and one mechanical inclination meters were used to measure the hoist’s inclination. The desired target was to hold at 15% grade.

The test was a success at over 15%!

EPB holding at 8 degrees (over 14% grade). Hoist at maximum inclination of 8.6 degrees (over 15% grade) and EPB held the coach.
