The 6.0L is a great engine...the 6.0L is a great engine...the 6.0L is a great engine; I keep telling myself if I repeat it enough I'll convince myself to not pull the last of my hair out. My little issue with the Pavement Princess is on it's 6th week and the truck hasn't left town; and with the exception of when I turned it around...hasn't left the driveway either. A good diesel mechanic I am not...but at some point there has got to be an end to the madness.
