What's your true, no BS fuel mileage with that 14? My buddies 14 hemi halfton is doing better fuel mileage on the highway (empty of course) than my 05 Cummins, oh and diesel is currently 10% more expensive than gas at the pump.
I remember the first time I drove my Brother's 90 Cummins 5 speed, it got 30MPG Imperial those days are gone (although they do live on in the imaginations of some).
