mac4440 - 5/27/2009 12:20 I don't know how some of these guys get the mileage they claim. . They must not use the same measurement as I do. I could never get more then maybe 16 out of my 2002. Avg just under 12 once pulling a steel stock trailer with livestock and tack down to Houston and back. Either way, that's a lot better then the 08 Dodge with 6.7L I drive now. 14 tops on it, down to 9.5 pulling that same steel stock trailer.
