Avion travel trailers are small recreational vehicles intended to be towed behind another vehicle without reqiuring a fifth-wheel hitch. Vintage Avion trailers from the 1950s and 1960s are considered collectible by many vintage RV enthusiasts.
The original Avion travel trailers were produced by brothers Loren and Robert Cayo along with their business partners beginning in 1955. Avion trailers were originally named Romany trailers in reference to Romany traveling caravans, but protests lead the company to change its name to Avion. The few early models that shipped with Romany branding were recalled. The Avion company was acquired by RV manufacturer Fleetwood in 1976. Fleetwood continued to produce and sell versions of the original Avion trailer design under that name until the 1990s.
