Some more great video of Moab can be seen on Rick Russell's Sidekick Offroad DVDs. Naturally, these guys are taking the toughest trails, so you can see what the most difficult stuff looks like. For those with stock rigs, have no fear, though--there are plenty of great, scenic trails without the higher difficulty ratings. If you can swing it, however, I would highly recommend at least one locker--it will greatly increase the number of trails you can take, even in an otherwise stock rig. The slickrock out there, which is anything BUT slick (it's more like sandpaper...at least when dry, anyway), can give you incredible traction when you air down--it will blow your mind how steep of an angle you can drive up! For the record, Pritchett Canyon is widely considered the toughest trail, so if you see video of that one, you've seen some of the best obstacles out there.
