I have a 02 f150 with the 4.2 set up as work truck from factory,5800lbs is max trl weight, mine is 4900 dry. It does ok but I wouldn't want to pull it across the usa or the mountains a lot, for my limited towing twin sway bars & a leveling system it does fine. If I ever get to retire 1 day I will upgrade both truck & camper .373 rear end with limited slip has been as good as most 4 wheel drives I have owned in order to get to work. I no longer think I need a 4x4 for any reason,a Honda 4wheeler keeps my truck out of the mud lol
