Its nothing really insane, but I was in my "New-to-me-Toyota," testing it out for the first time on the Rocks. It did quite well for having bald, aired up 31's. Actually I was really impressed with its performance, the wheelbase adds so much on the super-steep rocks, incomaprison to my Heep. The best part about it all was that I didn't have to worry about getting it all scraped up! Its a daily driver, but its not going to be a Beauty Queen. I need to do bumpers and rocker protection soon! These Rocks are in Utah, a place out in the Desert called Lil Moab. Its about a 30 min drive from civilization, but well worth it!
