insane camper

If it can't come off, it isn't a camper

....pure speculation on my part: I'll bet that the "living unit" unfastens via in-cab switch, and the/a hydraulic tilt-lift allows the box to be unloaded ?

Dak makes a good point: the right tool for the job. I foresee this unit being at home in the wide-open plateaus of South America, and the wide open deserts of North Africa and, further south in Namibia (there-around), where the 3000 kilometer fuel tank and on-board self-containment would thrive....
