Bob, will you be towing an open or enclosed trailer? A F150 can be optioned to tow as much as my 99 F350 Dually is rated for, but I personally prefer the extra stability the heavier truck offers, especially if an emergency situation arises. My old 74 F350 ramp truck with a 390 4 speed served me well for 26 years, I always feared a high speed panic stop, since all the weight was on 2 axles. My 99 F350 has large 4 wheel disc brakes, and with the added braking the 4 wheel trailer brakes provide, despite the extra 5000 pounds, the Dually/trailer combo stops much better. With a light duty truck, I would be concerned that the heavy trailer could push the truck around if a problem arose. If you don`t already have a truck, and had a budget in mind, I would rather have an older F350, or at least a 250, over a F150. I really like the dual rear wheels for stability in a crosswind too. Although I seldom use the 99 F350 empty, the V10, 5 speed 3.73 gear combo has given 15 MPG on the highway, with the 9000 box behind, usually drops to 8 -8 1/2 MPG, but since I normally only put about 2500 miles a year on that truck, its much easier to pay more for gas than to have truck payments.
