Hells revenge is a lot different that crawling over rocks in the sierra, and yes, I have done both. Heck, we all saw the video of that guy in the cown vic on hells revenge. If you think the Raptor is a rock crawler, come on out west, I got a trail you will love (no, it isnt the rubicon).Why? I posted pics of some preproduction Raptors being tested on Hell's Revenge in Moab by Ford. Its pretty obvious the truck can do it.
