Cave Campers

I'm not sure I understand who wants one like that without a toilet or cabinets. Maybe someone who owns one will post. I could see potentially if they made tie downs to hold containers, etc for removable storage. However, I do have friends that built their own frames inside aluminum toppers for hunting. I don't know if that model would support weight inside off truck or not. Support by the tailgate is kind of cheesy.

I'd prefer a Four Wheel Camper popup shell instead. For the hardside, a Capri Camper like this one http://capricamper.com/models/retreat/ is similar with a bit more finish.
