Haven't read this whole thread but I'm on my 2nd Ecoboost F150 after the first one was totaled. They pull great especially in the mountains. The tow-haul mode on the trans is very impressive too, as is the ability to lockout upper gears.
One word of advice - if you are at all interested in the big towing mirrors they've changed the packages on the 15+ and now you HAVE to order them separately - they are no longer included in the max tow. And they are EXPENSIVE to add after the fact - like they could be several thousand dollars depending on model and options. Get them for $275 as an option. This has been the only problem on my 15. We had it shipped over from another dealer and we thought it had them only to find out it didn't. I didn't think it was a big deal and went ahead and took the truck thinking I could easily do it later. A bunch of us on an F150 forum are still trying to figure out which one goes with which truck as there are something like 9 different mirrors.
