Sounds familiar, first one my family had was a 10ft Chinook camper on a beefed up 1967 Ford F-150. Was the same thing, porta potty and small water tank with a hand pump at the sink. Was totaled a few years later when the differential exploded while my father was driving down the freeway. He ended up wrapping it in roughly 100ft of chain link fencing while taking over a hillside. Left rear corner of the camper was smashed in, truck frame was damaged beyond repair and my father got away with bruises and a bruised ego. Only had one other RV trip after that, in 1973 he rented an 8ft Six Pac camper and put it on his 1963 Chevy C-10 that replaced the Ford. Took it on a two week trip across Washington and BC, got home and took it back after washing it. My trailer is the first RV anyone in the family has had since
