Now, also understand that there are MANY guys in moab who know and understand that they dont want to beat up their vehicle, and they understand as well which trail leaders do easier stuff, and which ones challenge themselves.

But, thats a hard thing to explain to a first timer, I think because when they do the first day and they see the capabilities of their little VX, they want to see it do more and more.... until something breaks, then its really a bummer. So, I dont want to lead someone into something where they are going to break their vehicle, and not be able to get home without spending $$$$$$$$$$.

I think mark hit the nail on the head. I think the best advise for a first timer might be to ask around and see which trail leader they should be following that does a trail at their skill level. Good advise for the upcoming years (thanks ash)
