knock on wood, I have not had a problem with TT4. Plenty of rock crawling and the like. Had a slight pulse rate jump once thanks to ABS though. Coming down a steep trail with no place to go and the ABS let the truck go a little further than I would have liked.
Love to get my hands on the elockers. Problem is I keep hearing available soon, seems like for the last year soon.
