My mother in law has a 12 dirtymax and it is a work horse and a half. In all of the comparisons the duramax is given the best marks for performance, mileage, and driveability. I know it will blow the damn 33" tires off like its nothing. She got a smoking deal on it. It will out tow out stop and generally out perform in every area the fords. Now interior is a different story to each his own.
