I have a 2005 F350 Harley Davidson 6.0 litre and I just love this truck. Between my Dad and myself, we have had 10 Ford diesels going back to 1989. They have treated us very well. On a couple of the trucks, we had over 250 000 miles on them and never experienced anything serious. I am really struggling over my next truck as I haven't heard a whole bunch good about the mileage on the new 6.4's. I have heard about 12-14 mpg highway and as poor as 5-6 mpg towing.(this is based on the Imperial gallon which is 4.5 litres compared to the US gallon, which is 3.8 litres).
