Those are 37 12.50 17 BFG MT's on there. I did not raise the front at all. The tires would stuff just a little at full flex. So I see no need for the front end leveling kit. The programmer is good idea too. you can change the shift pattern and rev limiter. You can also look up DTC when your out wheelin and even clear them out if needed to get you back home. SOMO offers teh SUT roof rack and bed rack. The factory cover is locking and the bed rack mount to that OR you can mount the rack to the truck itself without the cover.
It was nice having the bed of the SUT for hauling around crap, but the SUV does have a ton of inside room. If youhaul around tracor parts and such, I'd go for the SUT OR get a husky liner or equivelant for the rear of the SUV.
Happy hunting.
