Fuel usage of the diesels seems to be a topic of interest here, so I thought I'd post this- Drove from Kamiah Idaho to Helena, MT today towing a 27 foot camper that weighs about 6500 lbs as is. Can't remember the exact distance, and I am too free kin' tired to go out to the truck and look, but it was between 250 and 300 miles- Got 11.1 MPG according to the on board computer which checks out dead nuts on when I fuel up. Drove about 50 MPH over Lolo Pass and had bad cross winds from Missoula to Helena and drove 65 MPH on that portion.
