I was there with my stock 2005 Offroad. I only added the shrockworks rock sliders. I would have preferred a lift but didn't have one, so I heard my frame and trailer hitch scraping more than I wanted.

There were at least two other 2005 S models there, but each of them had bigger than stock tires and sliders. One of the S models had a lift and the other was not.
I can tell you the rear diff locker helped me up many different places. I also used the hill decent feature when going down some very steep sections. Those things were well worth the extra money.
