All you can do is what you feel comfortable with, the more you go, the more brave you'll get. You'll learn to get an eye for what you can do and what you want to stay away from. Just this past weekend, we had 2 stock 4-door sidekicks that were going places I wouldn't go! There were guys with Lifted Jeeps on 33's that couldn't believe what they were doing, it was impressive, but they were experienced wheelers that new the trail.
