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
Seems silly to me. Not hard or heavy to put the cabover. I can't see a market unless it is someone who can't or does not want to climb in and out of a cabover. Might as well just get a tall shell canopy and customize it a bit. I think this will be a dud.
