I have an 09 F150 with the 5.4 and the full towing package. I would have no hesitation towing that weight. Mine has 90k miles on it and it's being traded in on a new truck. Two reasons, I travel long distance across country and don't want to be stuck in Nebraska with a bad fuel pump or sensor for 2 weeks waiting on parts at a small shop. If I was staying more local I would have kept it.
