I did this a few months ago with GATR in a Titan Crew Cab short bed on 32s. I can almost guarantee some scratches as some of the trails get very narrow. On a couple of the turns, and I had to maneuver several times to make the turn. There was one spot I had to go through a tree and a boulder while off camber, it took several minutes to go through. Just as I was about to clear it, my rear end slid towards the tree and smacked it. I dented the quarter panel and broke my tail light.
I also bent my Nerf step bars pretty badly, and the plate that holds my towing electrical connection. Since he's on 37s, he shouldn't have that problem.
We were also told to stay off of 93B, as this is more for modified rigs.
Here is an hour long video I took from the trip:
