I looked at those. They're expensive ($2000-3000+) and fugly and don't do anything a $20 set of levelling blocks cant do 10x faster.

My biggest red flag was the reduction of ground clearance. If you like to go off road or at least camp up on fire trails...or even many roads in major Nat'l Parks like Glacier or Canyonlands, I'd be worried about wreckin' the livin' [censored] out of it and having it take part of the camper with it.

If you like to camp on flat pavement like all their gallery pics show, I guess it'd be fine, but then you might as well just buy a trailer.

My $.02...
