Also,
If
I was going to go all out on a rock climbing 4x4.......why start with a Jeep at all? The Jeep also had to be built originally, for use on the road also.
I would skip the all the weight B.S. and get a tube buggy to tow with my H2.
This one was for sale recently for just over $20,000. The tube frame was welded by a welding instructor at a tech school and the vehicle has twice what he's asking for it invested in the parts.
I have no doubt that it will outperform most Jeeps for less money.
