Great picks, to bad about the Toyota (hehe). Trails in Texas seem awful short, but really, really wide.
Question, the one jeep with the tire in the back. I run a similar setup, to get some weight off the back. How is the tire mounted?
Texas has a lot of different types of venues from granite escarpments, to twisty tight trails, steep hill climbs, sand, etc...The trails at Walnut Creek are actually VERY tight. Through many areas of the ranch, you have to pull the side view mirrors inward or lose them. I actually slid into a tree this weekend on a tight off camber section and got to test out my AEV trail corners. We had to remove a rear tail light so that it wouldn't be destroyed.
I use a cross pattern with ratchet straps to hold the spare 35" in the back. They are attached to the brackets that originally secured the rear seat. We have no kids, so there was no reason to keep that seat back there, and I would hate for an adult to have to get in and out back there- especially with the top on. I also relocated it to get a little more weight over the rear axle and off of the back, but also to achieve a better approach and departure angle. I love being able to actually see out of my rear view mirror as well, which is next to impossible with a 35" tire mounted on the back.
I can post up some pics of the relocated spare if interested. I also have the cooler mounted on top of it using a custom made shelf that keeps it from sliding around.
