Love it. No serious problems, but did have to have the "O" rings replaced on 2 injectors at 4,000 miles. Had a TSB done for surging under load. No other problems except the heavy right foot syndrome that most PSD owner seem to develop within a couple days of purchase. Have never driven anything but a Ford Diesel, so I can't compare it to any other mfg. Went whole hog and picked up an F350 Crew Cab Dually with the King Ranch package and a few more goodies back when the big 3 were having their car wars. Sticker was a few buck shy of $50K, but I was able to get it for significanly less.
