I would say that half or more of the trails here and the major obsticles on them can be avoided. Your stock VX will perform just fine on many trails, but there will be an ocassional scrape heard from time to time. Between Todd and I and others, we will highlight the trails that come easy, moderate, or hard. I have been out here for awhile now and the hardest trail I have done with my VX (no lockers, just lifted and bigger tires) has been Strike Ravine. There are some obvious trails that I just won't touch though, Pritchet Canyon, Moab Rim, and some more of course.
If anyone would like info on the trails out here in more detail, just send me a note.
