anyone running the 567 with 80 inch sleeper? What kind of fuel mileage do they get with the performance x15? I’m not one of the mpg nazis who need 8 but would prefer atleast 5 pulling end dump at 80k.. what is bobtail weight? Anyone purchased a x15 performance recently and remember what the actual Cummins extended warranty cost? Not the 3rd party stuff
Kind of thinking about trading the voovoo for one and would like some info that doesn’t come from a salesman lol
Thanks
