They're great trail rigs, like I said. They are full sized trucks, though. They will only go where they can fit. I have personally seen FJ80s end up with body damage and have significant trouble where the smaller rigs drove right through.

I'm willing to admit the disadvantages of an Xterra when compared with a SWB. However, we have advantages, too. SWB are more likely to flip backwards on steep obstacles.

A popular mod for Jeep-based rock buggies is to lengthen the wheelbase to ~103". They do it because they want the advantages the extra wheelbase gives.
