It just looks bad. There is very little weight up high. I've been on a lot steeper side hill than that, but over a long time and by degrees testing the waters, so to speak. It's all by feel. Don't need no stinkin' tilt-meter. There is a point at which it will go on it's side but I have not gotten there yet, at least not in the TC. During my hardcore jeeping dayz i rolled my CJ-8 maybe a dozen times, each time learning something new about the edge. Nothing on the roof. All weighty objects stored down low. Jacks off. LSD or locking diffs help on rocks but not much on sand. You might get a little lift to get the breakover angle and clearance in general to be taller. BTW, I would say your loaded TC weighs about 11K pounds.
Basically, try it with some other vehicular company. Since you already jeep, just apply those techniques to your TC. Just jump in and make your own mistakes. Your own mistakes are the best teachers. Adjust, Overcome, Make do, Make it work. Have a great time doing it. Ours on a short bed with all the over-time recommendations above:
