the power stroke websight has a lotta of info,but you get to hear from all the complainers. we have two of them an'11 and a '12,the '12 I have had a little over a year now and it's got 28,000 miles on it,never been down once,have a sale barn about 75miles away that we haul fat steers to with a 35ft featherlite trailer.
    this fall pulled two 600 bushel wagons to town with it,made several trips with that combo,wife was driving it to work during the polar vortex.
    all in all they have been good trucks for us,get 17-18 normal driving,20-21 freeway,10-13 pulling something. the engine braking feature in tow/haul is nice .like another poster said, boatloads of power.
