1976 GMC Birchaven 23’ Motorhome

This 1976 GMC is a 23′ motorhome that features a Birchaven floor plan with a galley, a convertible dinette and sofa, and a bathroom with a shower. Its interior has been updated with replacement front captain’s chairs trimmed in gray leather along with a bar, a Suburban oven/cooktop, a flat-screen TV with a sound bar, vinyl flooring, an aftermarket head unit, and a rearview camera mirror. Power is provided by an Oldsmobile 455ci V8 fitted with Doug Thorley headers and linked to a three-speed automatic transaxle, and the vehicle rides on quad rear airbags and 16″ Alcoa wheels over disc brakes. The exterior has fiberglass and aluminum bodywork finished in white with multi-color stripes in addition to LED lighting, an awning, a shower, and a rear ladder. An Onan generator, a water heater, and a roof-mounted air conditioning unit and solar panel are additional elements. Acquired by the seller in 2019, the vehicle was later placed into a reported period of long-term storage. This GMC motorhome is now offered at no reserve with service records and a Washington title in the seller’s name. Initially offered in two lengths, the GMC Motorhome was produced from 1973 through 1978 with a low, front-wheel-drive chassis. This 23′ example is said to have been repainted under previous ownership, and the white finish on its fiberglass and aluminum bodywork is complemented by blue, gray, and red stripes in addition to compass rose side graphics and Toronado badging. Aftermarket lighting additions include LED headlights, grille parking/turn signals, driving lights, yellow fog lamps, clearance lights, and secondary brake lights. The vehicle also has a roof-mounted air conditioning unit, an exterior shower, chrome-finished front and rear bumpers, a rear-mounted spare wheel, and a rear ladder. A DISH satellite TV antenna is installed, though it requires a subscription for use. Some of the gallery photos were taken in 2025.
