For many people, traveling with a camper is a relaxing hobby that allows them to escape the rigors and schedules of everyday life. In the mid-1920s, leisure car travel grew in popularity and new types of vehicles emerged. House cars and travel trailers became popular with motorists who wanted to experience America in comfort. The vehicles included small kitchens and beds; some even had two rooms. Enthusiasts joined clubs, traveled between camps, and studied how-to books on topics ranging from construction to cooking.
