Posting here since it's a bit more this era (I normally live in the 67+ world, but have played around in everything from 60-79s. Hope to someday stumble across that elusive 55.1 NAPCO dream truck... And this is what I'd stick in the back of it. Not mine, it's pricey, but I've never seen one in this condition. Campers weren't exactly a common purchase for truck owners until the craze hit mid-sixties, but sure would look at home on a 47-55.1. Don't see any obvious sleeping arrangements, but I think the table folds up and the seats slide out to form a bed. Guess that's why they invented overhead campers.
