I love the flip idea on a pickup truck. My buddy had a similar setup - a Wilderness camper on a Taco and he said it was ok. The really big downside is you still need to break camp and fold everything up if you want to do some exploring or if you have to go someplace. My friend was camping alone out in the wilderness hunting and some dude drove into his camp - he'd got a buck down and wasn't able to track it. My friend had to break camp down, pack everything up, then drive across the national forest trying to help this dude track the wounded buck, got that done, then had to drive all the way back to his camp and set everything back up. Just a pain in the butt.
Also, I don't see the major advantage of this JK Flippac over a roof rack and an car top tent, or even an off-road tent trailer for that matter. In a pickup, you've got the rear bed access, but in a Jeep how is that going to work? You've got roll bars, seats and all sorts of obstacles.
