Talk is cheap until you own one. Your 6.0 ran like crap because you didn't take car of it. Simple and sweet. Do what Ford tells you to do and it will never stop running. I chose the weakest of the 6.0 Diesel motors the 2003 just to spite people talking smack about the 6.0 being junk.

Oh and put 10,000 lbs behind the that Dodge and see how much fun you have going up a hill without 4.10s, then you'll appreciate the well design of a International Motor.
