There was an early discussion thread about simple, inexpensive living and camping. Looks like Travel Lite has come up with a camper just for that market. Rayzr Truck Camper
We have one of these we brought back from Colorado quite a few years ago. Sold it to our son who used it several years then retired it to the back 40 and there it sits today. Sad end. Scavaged parts over the years and the roof still doesn't leak.
