My parents just towed a 30 some ft travel trailer from WV to Florida with his 03 f150 SC 4x4 with a 5.4 and 3.55's. Only upgrades are BFG AT (LT) and upgraded rotors and pads. He said the truck did great with the WD hitch. Downfall was mpg. Low of 6-7 in the mountains and 8 once he hit flat. They bought the truck new and bought a fifth wheel son thereafter and towed it all over the place. They recently changed to a travel trailer as Florida is their new winter destination so it will stay on a lot there. The fifth wheel was 6900 lbs dry and the new one is 7500 lbs dry. I would personally not go over that weight with a half ton. Find a F250 gas if towing often. I've had a 5.4 F250 with 3.73's and a 5.4 F150. Gas mileage was similar enough that if I would have towed more I would have kept the f250 as it is simply larger and more stable towing. My 0.02.

The maximum for your vehicle would be 7,700 lbs. However, as the vehicle is 14 years old, you should not attempt to tow this much weight as your engine has most likely lost power over the years and your transmission has worn. The extra weight will cause you to break down and, most likely, somewhere where you cannot have it easily or economically fixed. Routine towing puts a lot of stress on any vehicle and you should always make sure you have plenty of towing capacity in your vehicle to haul the load you need to handle.

Not the right truck for the size of trailer you want to tow. Move up to an f250 or f350.

Yah I'd recommend a f250 diesel for that. Careful on which year diesel you get though. Some years are bulletproof while some had tons of issues. I don't know which engines were bad or I'd list them but I believe the 6.0L is the one to stay away from.

That's too much I have all of fords diesels from 99-13 in my trucks or have had and I would go for a 01-03 7.3 250 a great truck all around and with a chip and exhaust (and a light foot) you will have all the power you would need and not bad mpg even pulling that load
