I have used an F-150 7700 for the last 3 years and it has been a great truck. It constantly impresses me as what it can do. I just got back from a 3000 mile trip to Florida towing a 26.5' Crownline boat that weighed in at 7,400lbs. It was easy going and the truck barely knew it was back there. Anyone else use a F-150 7700 or F250LD?
