The more 'full' size the camper the less its off-roading capabilities.
The taller, bigger and heavier rig, just that much more work to negotiate route. IE in the earlier linked TC winching video, other than that much weight stuck in the mud the real issue was potential for tipping over getting up 2' side hill drop. If it had been a pop top or a smaller hardside, even at same weight, would have been a LOT less risk. Though he went off the shoulder of road, some trails that would be the route as far as off camber.
off topic but Thanks for checking and clarifying Kayteg1, was really curious as I'd never seen that small of tubing used on Torklift inserts. And the size verses wall strength because I disagreed on the "little consequence" comment.
While increasing wall thickness will increase strength for a given size, increasing size verses wall thickness yields more strength. Then again never heard use of "schedule 60" referring to 1 1/2"x .120" wall steel shapes.
