Sunday morning, I'll leave San Antonio, TX headed for Vance AFB in Enid, OK (wife's TDY) for a week. This will be my first distance travel on my 'new' '03 Cummins H.O. Though I've driven diesels before, they were always big truck diesels and the fuel mileage sucked, to be blunt. Right around 7.5 at the max.
I'll be trying for a consistant 65 mph and using cruise as much as possible. With the 4.10 gearing on the beast, what should I be looking at in fuel mileage? I've seen the overhead display showing 18.5 when I bought it two days ago, but am now showing right at 16.8. Of course, I've been riding around in town quite a bit.
I'd appreciate any feed back.
