The 7.3 gasser is aimed right at the towing market. Specs haven’t been released but I bet it’d handle that load just fine in F-350 DRW.I doubt I would go gas. I have 4600 pounds of camper in the bed and 7000 pounds of horse trailer being pulled. That is diesel country in the hills. Now if I didn't have the horse trailer I might consider it
That said, sticking with used vehicles +/- tossing $4,800 into them now and then is much cheaper than depreciation on a new rig.
