Seen at the RV/MH Hall of Fame. This 1954 Yellowstone 18' Travel Trailer is one of the relatively high-line models built by Yellowstone founder Elmer Weaver in the late 40s and early 50s. Bright aluminum exterior and all birch interior with residential type appliances. Founded in 1945 as the Yellowstone Coach Company. The Yellowstone travel trailers were built and sold in Wakarusa, Indiana from 1945-1990. Yellowstone trailers were well built and the travel trailer of choice for carnival employees. Yellowstone was one of the very few companies that didn’t venture into the larger type mobile homes. The RV/MH Hall of Fame is a museum in Elkhart, Indiana that features a variety of historical recreational vehicles from Airstream, Winnebago and other American makers. Founded in 1972 as the Recreational Vehicle/Manufactured Housing Heritage Foundation, the museum opened in 1991 and in 2007, moved into its current location. The foundation is a non-profit organization. The primary building, Founders Hall, is complete with artificial trees and other plants to create a simulated RV campground. The museum features a variety of recreation vehicles dating back 100 years and continuing through the 1980s. The oldest vehicle on display is a 1913 Earl Travel Trailer and is the oldest surviving specimen known. The oldest Winnebago and the smallest Airstream ever built are also to be found in the museum.—Wikipedia
