Wheelbase and Torque are two important factors in towing. I frequently trailer a race car trailer which is significantly heavier than any F boat. My tow car is a diesel excursion with a banks power pak upgrade. Average 16.8 mpg towing (heaviey),19.8 regular towing light (about 2800 lbs total) and 20-21 mpg highway. Surprises the hell out of me at every fill up! Supposedly the truck makes almost 700 ft lbs of torque (according to the paperwork). All I know is that it pulls hard, smooth, fast, and easy. NEver overheats, never breaksdown and always and I mean always people get out of the way.
