Idk either. I live in s. Fl. Never off road just on some broken paved roads. Never any problems with my other trucks. Mine was so bad, wife didn't want to ride in it. Yeah, they just said take it to a car was and wash the leaf springs. But that with the strange shift points ( yes just had the computer update) and the cruise control up and down rpm changes on highway, just didn't feel comfortable with the truck. But pretty nice interior, lol.
