Prior, I used a Ford 150 truck with 5 liter and automatic. It was bullet

proof! I changed the ATF every 105,000 miles whether it needed it or not..

I'll second the F-150. They come in various towing flavors, with and without the towing kit. Permissible towing weight sans tow kit depends on final drive ratio. I chose the 3.77 rear which has a 4600lb max towing weight for mine. However at 75mph it tends to shift up and down between 3rd and OD. At 85mph, it sticks in OD. At 65-75mph in rolling mountains, I stick it in 3rd and leave it.
