Heres my camping setup from 2 weeks ago I love it, and going again this weekend
No tent ? You sleep INSIDE the vehicle ? That doesn't look very comfortable to me at all...
I've heard of others using the interior as a "camper" and while I'm short (5'6"), I couldn't do it. I laid down the back seats, not enough room. Folded the passenger seat, nope.
It'd probably be more comfortable to recline the passenger seat all the way back and sleep there instead of trying to use the back area.
Tents can be had pretty cheap, especially for occasional weekend camping.
Sleeping inside the Renegade in an emergency ? Yep. While I'm at home loading up my camping gear ? I'd toss in a tent.
