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
I like it, and there is definitely a market. Price and weight are great for someone who just wants a hardside choice to step up from a tent. Either the base or front-bed versions would be a good match for the new Ford 1/2 ton trucks.
