At GMCMI, our dedicated volunteers work to create an engaging and welcoming environment for every GMC Motorhome owner. We share technical knowledge, celebrate the classic coach, and build friendships through rallies, workshops, and national conventions that create memories lasting a lifetime.
We believe in the passion, expertise, and creativity that every member brings to the community. GMCMI provides opportunities to learn, connect, and discover new interests through educational sessions, travel experiences, and shared support among fellow owners.
Get to know the volunteers who help organize our events, maintain our resources, and keep the spirit of the GMC Motorhome community alive.
We believe every GMC Motorhome owner has the potential to learn, grow, and connect through shared experiences. Our rallies provide opportunities to explore new destinations and build lasting friendships within a supportive and enthusiastic community.
“Being part of GMCMI has completely transformed my experience as a GMC Motorhome owner. The rallies are an incredible mix of learning, laughter, and friendship. I’ve gained more technical knowledge in a single convention than I did in years of owning my coach — and the community makes you feel like family from day one.”
“I joined GMCMI to find support with restoring my classic GMC Motorhome, but what I found was so much more. The people, the shared passion, and the hands-on workshops at the rallies have been invaluable. Every event feels like a reunion, and I always leave with new ideas and lifelong friends.”
More than anything, we love the family we've been welcomed into! There are so many others who love and enjoy their coaches like we do. Folks who take off and explore... These are a great group of folks who are ready for an adventure and just as ready to help someone problem solve any problems or concerns on their coaches.
What I love about this group is that people will take time out of their own lives to help me get my 'wreck' of a camper going... the kind of project that can make you think, 'Oh my God, I'm done. Not one more thing.' Suddenly I'm turned around. And it makes me want to show up, contribute, and be part of it.
"On a cross-country trip, I utilized the Assist List in New Mexico. Hal St. Clair and I spent hours tracking down an alternator issue. That's what this club is about — you're never alone out there."
"We used the Assist List once in New Mexico, and have been grateful ever since. Our proudest accomplishment has been living and traveling in the coach for 30 days in a row. Being part of GMCMI made that possible."
