The Stabile-Lift is cool but interferes with off-road use. All things considered, a truck camper is probably most people's first choice for back country travel but a van conversion is a close second (or preferred by some). I have a 2 wheel drive pop top van that is done with a Ford Econoline van but has an interior like the old VW campers. It has a little over 8" of clearance with stock size tires and with its short wheelbase can go lots of places most rigs can't. However, it's a bit primative (no bath/shower or standing headroom unless the top is up). As I get older, I think about selling it and getting another slide in camper for my 4x4 pickup because I want a 4x4 rig but also want a proper bathroom on board.
If you have lots of money, a Sportsmobile van conversion on a 4X4 Sprinter would be nearly ideal. Road Trex has a $180k Sprinter 4x4 designed for boondocking. Then there are companies like EarthRoamer and Provan that make, essentially 4X4 Class C conversions as frame mounted truck campers using 1 ton or better trucks. These are serious rigs for serious money and if I could afford one, that's what I'd get.
