GMC motorhome
The GMC Motorhome is a recreational vehicle that was manufactured by the GMC Truck & Coach Division of General Motors for model years 1973–1978 in Pontiac, Michigan, USA — as the only complete motorhome built by a major auto/truck manufacturer. Manufactured in 23 and 26 ft (7.0 and 7.9 m) lengths, the design was noted for its front-wheel drive and its low profile, fully integrated body. In contrast to most motorhomes which were manufactured on drivetrain-equipped frames supplied by a chassis manufacturer; GMC designed, engineered, and built the entire vehicle, and in most cases the interiors, completely in-house. Empty shells were also supplied to other RV manufacturers for interior outfitting and to specialty manufacturers for custom outfitting, ranging from mail delivery and mobile training facilities to people movers and ambulances.
