Truck Decision UPDATE: Decison Made (pending)

I have a Ford F350 6.4L dually and after I purchased it 3 years ago i almost had a heart attack when I started reading all the posts about the powerstoke. I wound up doing a lot of research and talking to my diesel mechanic at lenght. What I got from him is that the 6.0L is bad. He has said that there are shops that will not work on them because they are going to fail. He has said to me that the 6.4L is a much better engine and they have not seen the failures like the 6.0L. I have also read that a lot of the problems with the 6.4L are due to people not taking care of the engine and abusing the truck. I love the truck it carries my camper comfortably with no problems and with better gas milage than the Class C I had.
