in moab as long as you do not drive past your ability the Jeep is way more ready than you are. I mean there is a guy on youtube that does many trails in a Crown Vic.
Moab has more danger on sometrails with driver error than most places. you get high up on things. If you do something FUBAR it can be a real "Houston we have a problem". fall of of hells gate at thetop your in a real S>H. same on escollater. There are not real hard just a matter of where you place tires. Compared to trails like Rubicon and others you get FUBAR might just flop on its side or bash a quater panel.
Wells books tend to be on the lighter side of trails and wont include the real hard stuff. For good reasons. Liabilty.
If you are new to offroad I hope you are going with people or a club? Not that spotters are the end all too. I have seen spotters giving the wrong info and it never ends well if that happens. If the spotter has a beer and cig might want to rethink the information.
My fav bad spotter video at Moab. If you plan to run it do not show this to your wife. this is not a hard thing to run BUT......
