It featured a fiberglass monocoque body and was built on a Ford or Dodge chassis. The Chinook was innovative in its blend of luxury and compactness, offering a fully equipped living space in a small, easy-to-drive package. Despite its loyal following, Chinook RVs were relatively expensive, and the brand struggled to compete with larger, more affordable RVs. Production eventually ceased in 2005, though the Chinook remains a cult favorite among RV enthusiasts.
GMC Transmode (1973-1978)
The GMC Transmode was a variation of the iconic GMC Motorhome, designed as a stripped-down version that allowed buyers to customize the interior to their liking. It featured the same front-wheel-drive layout and aerodynamic design as the GMC Motorhome, with a fiberglass body and a low profile. Despite its innovative concept and the flexibility it offered, the Transmode never gained widespread popularity. The high cost of customization and the niche market for such a vehicle limited its appeal, and production was discontinued after just a few years.
Revcon 250 (1970s)
The Revcon 250 was a pioneering RV that featured an all-aluminum body, front-wheel drive, and independent suspension. These features provided superior handling, fuel efficiency, and a smooth ride, making it a standout in the RV market. However, despite its advanced engineering, the Revcon 250 struggled to compete with more traditional, less expensive RVs. The high cost of production and the niche market for such a specialized vehicle led to limited sales, and Revcon eventually discontinued the model.
Safari Trek (1991-2008)
The Safari Trek was an innovative Class A motorhome known for its unique “Electro-Majic” bed that descended from the ceiling, allowing for more living space during the day. Built on a Chevrolet P30 chassis, the Trek offered a compact yet luxurious experience with high-end finishes and ample storage. Despite its clever design and strong following, the Trek never became a mainstream success. The complexity of the bed mechanism and the higher cost compared to larger motorhomes with more conventional layouts limited its market appeal.
Winnebago Elandan (1980s)
The Winnebago Elandan was a luxurious Class A motorhome introduced in the 1980s, featuring a distinctive, futuristic design with a wide, rounded front end and large panoramic windows. It was equipped with a spacious interior, including high-end materials, advanced technology, and a unique split-level floor plan. Despite its innovative features and premium feel, the Elandan was expensive to produce and struggled to find a large market. Its high price and unique design limited its appeal, leading to its eventual discontinuation.
Nissan Caravan Pop-Top (1970s)
The Nissan Caravan Pop-Top was a compact camper van that featured a unique pop-top roof, allowing for additional headroom and sleeping space. Designed for urban environments, it was easy to drive and park, making it ideal for city dwellers looking for a versatile RV. However, its small size and limited amenities compared to larger RVs made it less popular among traditional RV buyers. The Nissan Caravan Pop-Top was ultimately overshadowed by more spacious and better-equipped RVs, leading to its decline in popularity.
Colani Cormoran (1970s)
Designed by the eccentric German designer Luigi Colani, the Colani Cormoran was a futuristic motorhome concept that featured a highly aerodynamic, teardrop-shaped body. Its design prioritized fuel efficiency and stability, with a sleek exterior and a luxurious interior that included innovative space-saving features. Despite its groundbreaking design, the Cormoran never went into full production due to its unconventional appearance and high production costs. Today, it remains a rare and fascinating example of visionary RV design that was ahead of its time.
Argosy by Airstream (1970s)
The Argosy by Airstream was an experimental line of motorhomes and travel trailers introduced in the 1970s, known for their distinctive painted aluminum bodies, which contrasted with Airstream’s traditional polished aluminum. The Argosy was designed to be more affordable while offering the same aerodynamic benefits as traditional Airstream models. Despite its innovative design and loyal following, the Argosy struggled to compete with Airstream’s core products, leading to its discontinuation. The unique look and limited production run make the Argosy a collector’s item today.
Sunrader Toyota RV (1980s)
The Sunrader Toyota RV was a compact, fiberglass-bodied motorhome built on the Toyota pickup chassis. It featured a sleek, lightweight design that was both fuel-efficient and easy to maneuver. The Sunrader’s fiberglass construction made it durable and resistant to rust, while its compact size made it popular among solo travelers and couples. Despite its advantages, the Sunrader faced stiff competition from larger RVs with more amenities, and its small size limited its appeal. The model was eventually discontinued, but it remains a sought-after vehicle among vintage RV enthusiasts.
Bowlus Road Chief (1930s)
The Bowlus Road Chief was one of the earliest examples of an aerodynamic travel trailer, designed by Hawley Bowlus, the engineer behind Charles Lindbergh’s Spirit of St. Louis.
