I've got a 2000 Supercab Long bed - V10, 4x4, 3.73 rear end. Boat + trailer weighs about 7500 pounds. I get 15 mpg highway without the boat, 8 mpg with the boat. A K&N filter and Cat-back exhaust makes a big difference in acceleration. The only negative about this truck is turning radius. You need to think ahead at the boat ramp and strip mall parking lots. I'm keeping it until Ford's four wheel steering is available.
