Not too many complaints
I just completed an 1800 mi. round trip from Ohio to Maine/New Hampshire across Pennsylvania with my '03 6.0L/4l80e crew cab this weekend. With an empty 4000# gooseneck 10 mpg, on the return trip 10,000# @ 8.1 mpg. The truck performed flawlessly, very comfortable, smooth ride (considering the conditions), the truck could pass anything but a gas station. That is the only thing I'd change. I couple of climbs were difficult, but I kept it at a decent speed without having to rev over 3400 rpm. The toughest part of the trip was west through N.H. on a two lane highway (the only section where my tranny temp went over 160 deg.) D-max would be nice but not for the money, and the frequency of my trailering trips.
