You should be fine. Sliders are a good thing to have. At the very least remove your step rails. You should also give your truck the once over to make sure that everything (hoses, brakes, tires, etc...) is in good shape.
Please review the posts on the goneMoab website as well as on the forum.
I will be posting a low-res digital version of the event guide this week. It has important info.

See you in Moab,
