I'll just start by saying you are nuts for going in the middle of summer, make sure your cooling system is 110% up to the task of running the a/c while going very slow. And if you are wondering if your rig can handle hells, go watch the video of the ford crown Victoria on the trail, you can do most of it in 2wd. I would go check out Chicken Corners and the Gemini Bridges trails, as well as the road that takes you from Deadhorse Point and down to the Potash Rd, very easy but fun. Expect daytime temps of 101-104 and nighttime 80-83, and watch out for rattlesnakes. We live less than 3 hours from there and refuse to go between June and September, it is just too dang hot to call it fun. Does your rig have sliders and skid plates?
