I had an older 1998 5.4 Expedition and have towed a couple smaller boats with it. My 211 Liberator wasn't bad. My 237 PowerQuest Stryker wasn't too much heavier but on a better trailer and it was really as much as I would want to tow with that truck. My 200 Regal Destiny deckboat is pretty big, deep, and heavy for a 20 footer and that truck did OK, not great, not terrible, just OK with it. I have a newer 2004 Expedition now with the 5.4 too, yet to tow much at all, but same gear ratios and it drives out pretty similar, guessing will do same as old or real close. I think the PQ, trailer, gear, fuel, all loaded may have tipped scales just over 5,000 lbs maybe. That was the max I would ever want to pull with my Expeditions, even though they are rated for twice that. Maybe in a 3/4 ton it may be a bit better feeling, but if 3:50 gears and the 5.4....I guess anything over 5-6000 pounds is going to make you want a bigger motor. Happy shopping!
