What those guys said. My first three Moab's where done at stock height with 285/60/18 Terra Grapplers, no sliders and the stock Trooper skid plate. Just took it easy, listened to my spotters, and didn't have a problem.
On a similar note, we usually do a caravan of VX's on the Monday of Moab. As those to our East and North head this way, they pick us up as they go and we all roll into Moab together. Pretty dang cool seeing that many VX's on the road at once.
"The major difference between a thing that might go wrong and a thing that cannot possibly go wrong is that when a thing that cannot possibly go wrong goes wrong, it usually turns out to be impossible to get at or repair."
