My parents wanted to travel in the 1980s, but Dad hated hotels and restaurants. After trying a popup tent trailer, they decided it was comfortable enough but dangerous to tow (one windswept drive was enough). They ended up with a shell that sat on a truck bed but was removable on stilts like these. It was supposedly light enough for a half-ton truck, but Dad decided after one season to mount it on a full-size truck. They happily visited every continental state except Alaska and Dad sold it for a good sum a few years after Mom died. Theirs had a double bed, table that dropped down to support a single bed, sink, stove, heater, and storage, but no bathroom or AC.
