I have one the 3.0
I have one the 3.0 powerstroke diesels I just went into the dealer and told them I wanted one I had three to chose from.
After 4 weeks and a twelve hundred miles of which I pulled a 18X8.2X8.5 enclosed trailer 350 of them I am impressed.
My 2012 250 SD 6.7 got 15MPG highway the 150 actually beat it by 3.7MPG But then again I did not pull any hills this trip 99% of the 150 trip was flat ground but hey it did its job and never went below 75 MPH with the cruse on.
As I don't do the long hauls like I used to it's a keeper.
