The GMC Motor Home

General Motors built these Classic GMC Coaches from 1973 thru 1978 on its GMC Coach (bus) assembly line in 23 and 26 foot lengths.

The body is aluminum and fiberglass. Other than the steel vehicle chassis, the entire coach frame is aluminum. The firewall is aluminum as are all areas requiring structural metal sheets. No structural wood is used anywhere except in the floor, which is rigid 3/4" plywood clad with aluminum for weatherproofing. The roof is a one-piece aluminum sheet on aluminum structural members. These coaches are very solid and were built to last. Most of the 13,000 built are still in service. Some have over a half million miles on them and are still going strong.

All GMC Coaches have front wheel drive based on the Oldsmobile Toronado and share engine, transmission, driveline, and many suspension and steering components with the Toronado. The 1976 coach had the 455 cubic inch Toronado engine and the Toronado Hydramatic 425 automatic transmission. The air suspension automatically adjusts to road conditions and the air bags mounted between the rear wheels greatly reduce road noise and increase stability.

GMC Coach owners are very loyal and clubs exist throughout the US and Canada.




This coach was totally reconditioned by Cinnabar Engineering in 2000. With care, it should easily last another 25 years. Cinnabar Engineering purchased the manufacturing rights to the GMC Motor Home and offers a complete line of parts and services for proper maintenance of the coach. The coach had 85,000 miles on it when it had a frame off restoration, it now has 106,000 miles.

It’s the best buy you’ll ever make on a Motor Home. If cared for, GMC Motor Coaches have, since new, traditionally retained all of their value and this one has been totally reconditioned.

The only reason I am selling is because I have retired in Mexico.

The motor home is in storage, undercover at Fort Worth, Texas
