GMC Motorhome classic car for sale

History of the GMC Motorhome

The GMC Motorhome was produced by General Motors’ GMC Truck & Coach Division from 1973 to 1978 in Pontiac, Michigan. Unlike most motorhomes of its era, which used third-party chassis and bodies, the GMC Motorhome was designed and built in-house by a leading automotive manufacturer, making it unique in the RV landscape. GMC offered the Motorhome in lengths of 23 and 26 feet and constructed it as a fully integrated vehicle, not just a cab-chassis conversion. Its innovative front-wheel drive setup gave it a remarkably low floor and profile, with a flat interior surface throughout—unusual for motorhomes of its period, which typically featured rear-wheel drive and higher ride heights. The GMC Motorhome’s use of lightweight aluminium and fibreglass for its body further differentiated it from rivals relying on heavier steel and timber constructions.

Model History

The GMC Motorhome entered the market in the early 1970s, an era marked by the growing popularity of recreational vehicles in North America. It did not have a specific predecessor within the GMC portfolio, as it was a ground-up design. The closest comparable vehicles before the Motorhome were custom-built coach conversions on truck chassis. After production ceased in 1978, no direct GMC successor followed; instead, the concept inspired specialist companies and enthusiasts to maintain and upgrade existing models for decades. The closest conceptual successors can be found among independent builders and retrofitters who continue to value the platform for its engineering.

Highlights of the GMC Motorhome

The GMC Motorhome stands out for being the only classic-era motorhome designed, engineered, and assembled entirely by a major automotive manufacturer—General Motors. The front-wheel drive configuration led to a spacious, remarkably low and flat interior, which increased comfort and usability. Most models feature a robust 7.4-litre (454 cubic inch) V8 engine delivering up to around 330 HP, paired with an automatic transmission. Standard interiors usually offered sleeping accommodations for five, fully equipped kitchens with ovens and refrigerators, full bathrooms with bathtubs and showers, numerous cabinets, and thoughtful storage throughout.

Engine and Performance, Transmission and Handling

The typical GMC Motorhome houses a 7.4-litre (454 ci) V8 engine, paired with an automatic gearbox and front-wheel drive architecture—a rarity among RVs of its time. This setup provides a notable 330 HP and enables a surprisingly even, smooth ride for a vehicle nearly five tonnes in weight.

The automatic transmission further boosts long-haul comfort, and the sophisticated cabin arrangement diminishes fatigue on extended journeys. - GMC Midas 277/1 Camper (Recognised for its classic original features and intact period décor)
