Knowing where they have come from with the 6 oh NO! and the 6.4... this may not be a bad thing. It certainly can't be any worse than the 6 liter was.
Not a powerstroke, but I bought a 2nd year model from Ford with a first year twin turbo engine and so far have had zero problems with it in the first 10,000 miles. (knocks on wood, lol) I am very impressed with it versus the other vehicles I looked at and think Ford really has it together versus some of its competition now. I think they are on the right track with their product line.
