Bought one last year. 4x4 Crew Cab with 5.5 foot box....best truck so far that I have owned.
I do get 22 mpg when empty and not bucking a wind. I average 18.5 with the box loaded, and pulling a 8" trailor loaded with wood. It doesn"t feel as if I am pulling anything.
I work with a guy that has F150 with the Triton engine. His wife has F150 Ecoboost....he says the Ecoboost will drive circles around his truck.
I work with another guy whose son is an engineer at Ford who helped design the engine...of course, he says it is the best engine Ford ever built....:>)
So far, I have had no issues with it and would buy another one if I could afford it. My wife won"t let me drive it because she likes it so much..:>)
