The 1978 GMC Royale Motorhome represents a significant chapter in recreational vehicle design. Built by General Motors and finished by Jimmy Motor Homes, it offers a distinctive style. This 26-foot RV is one of the final examples produced in 1978. It reportedly remained with its prior owner for over two decades. The seller acquired this unique motorhome in 2025. It retains much of its original character. This GMC Royale is a classic piece of Americana entering the market spotlight today.
Exterior and Unique Structure
This motorhome is finished in a clean tan color. Multi-tone accent stripes provide a strong period look. These original stripes do show minor fading and cracking. Exterior features enhance its travel capabilities. A retractable awning provides welcome shade at campsites. A rear ladder and luggage rack increase storage options. Furthermore, a receiver hitch adds towing functionality. The design is distinct due to its low profile. This GMC Royale is instantly recognizable among classic RVs.
Chassis and Suspension Technology
The GMC motorhome chassis is unique in its design. The front axle utilizes a torsion bar suspension system. This contributes to a smoother ride quality. The tandem rear axles feature adjustable air suspension. Controls for this Electro-Level air system are located near the driver. Steel wheels wear GMC-branded covers. They are fitted with Firestone Transforce HT tires. Recent service addressed the brakes and suspension. This included replacing front brake pads and calipers. Rear drum brakes were also rebuilt in September 2025.
Interior: Functional Living Space
The interior layout maximizes the available 26 feet of space. The main living area includes a dinette. This features a table flanked by two bench seats. The galley is equipped with all necessary amenities. These include a double-basin sink and a four-burner range. A refrigerator, freezer, and microwave complete the kitchenette. Wooden storage cabinets are found throughout the space. The upholstery and carpeting received detailing prior to sale. Central heating and air conditioning ensure comfort in any climate.

Storage is managed by upper and lower cabinets and a wardrobe. A full lavatory is situated at the back. It features a toilet, sink, and a dry bath area. The seller does note past water damage in the lavatory area. However, a prior owner reportedly repaired the leak and sealed the roof and windows. Additional details include a vent fan and wall-mounted speakers.
Engine, Power, and Performance Specifications
This motorhome is powered by a longitudinally mounted 403 cubic-inch V8 engine. This engine provides ample torque for moving the 26-foot body. It sends power to the front wheels.
