We started towing our F-150 4 x 4 extended cab V6 about 18 months ago so we could haul our Harley Trike in the bed of the truck. So far, no problems. It tows very well although we have noticed that it tracks differently than our old Honda minivan did. Used to be if the coach made the turn, then the van made the turn. Not so with the F-150. We had to stop going to a fuel stop we used to use because the F-150 required more room to make a turn.
