I owned a '96 and '01 Super Duty diesels and switched to a Dodge/Cummins in 04 due to all the problems of the Ford 6.0. I drove all three to about 100k miles and never had a problem with any of them. ZERO. I have a friend that is a diesel mechanic at a big Ford commercial shop and he said the 6.4 is awesome. He recommended his dad to get one and me as well. Couldn't be happier. Very quiet in the cab and smooooth. Yes it's a pig on fuel,but they all are. With some mods I am hoping on a boost on mpg. Hwy mileage is as good as any diesel trucks I have owned,about 15 mpg. around town it drops off to about 12 at best. The tires,wheels,and lift knock off about 2 mpg.
