History of the GMC Kingsley

The GMC Kingsley is part of the GMC Motorhome series, produced by General Motors from 1973 to 1978. These motorhomes were unique because they were the only mass-produced motorhomes entirely designed and built by a major automobile manufacturer. Unlike other RVs of the time, which were often constructed by third-party companies on a truck chassis, the GMC Motorhome series, including the Kingsley, was a fully integrated vehicle. This integration allowed for superior design cohesion and performance.

The 1978 model year marked the final production year for the GMC Motorhome, making the Kingsley from this year particularly significant. The GMC Motorhome series was ahead of its time, featuring front-wheel drive, an aluminum and fiberglass body, and a low profile for improved aerodynamics and fuel efficiency. These features set the GMC Kingsley apart from its contemporaries and contributed to its enduring appeal.
