I've had every diesel ever built, lots of em. Best truck-engine combo I've had to date , 2014 ford, power stroke, auto, 3.23 gear. Man this thing pulls! You wouldn't think so with so high of gear. I have three dodges and it out pulls all of them. Plus get nearly twice the fuel milage, loaded and empty. It has 30 k miles on it now if it goes to 300k I'll be happier.
