Stephen,
I haven't slid off any trails yet Knock knock on wood, so you would be pretty safe with me. Also you should ride with a stocker at least one day, so you can see how much they really can do. You will be amazed. A lot of the Ford engineers rode with the Big Dawgs at Truckhaven, but one of the guys that rode with me told me, he expected the big dawgs to be able to do just about anything, but he was absolutely amazed that stock trucks like mine (at the time it was pretty much stock) could do what we were doing. It really blew him away. Your's will do just fine.
