I guess none of you have prolly seen me towing, but my truck is an F250! The label on the fender says so!!!
I have pulled a 15,000 lb dozer on mine, but I have the trailer and such to do it. Also, I only pulled it about 2 miles on a county road. My buddy however, pulled the same dozer on a bumper pull trailer with a true F250, a 1997 with a 460 and I told him he was absolutely crazy. While loading the dozer, they actually lifted the rear of his truck off the ground, it was only in 2WD so there they were, chasing a truck and trailer with a half loaded dozer. Again only a short tow, but unsafe none the less.
My truck pulled the load no problem, I had electric brakes etc., the F250 did not and he pulled it on the highway!!! I gave him three kinds of h$##, told him that he needed to stop thinking about the dangers to just himself and start thinking about those he shared the road with. Of course he sighted that I pulled it as well, but my truck is a 1 ton dually and I never left the gravel roads, used a goose neck with working brakes, BIG difference in my book, but prolly not safe none the less. The goose neck is a tandem axle with duals on each side, 25,000 gross hauling capacity, not mine I have no need for it, but it towed pretty nice.
