I don't think so, but thats still pretty cool.
I think an ultimate Wrangler would have more usefull offroading stuff (air compressor, TIG welder, stuff like that maybe a few more lights, a little bar fridge...)
Wow someone actually built a Wrangler I like, but it's no off road rig. In fact I bet he doesn't even take it off road since there really is no damage on the body. But I guess if you spent 90 grand on something you wouldn't want to ruin it either.
