Fuel mileage, I know of no person who don't want better fuel mileage. But as long as the EPA is telling the manufacture how to build the Diesel engines the fuel mileage want increase.

I do believe if your towing heavy 17,000 and up and the mileage is between 9.5 to 12 mpg your doing fair, and when bobtailing your getting 14 to 20 mpg again thats not bad. Those numbers are from this past summer in a 2011 Chevy 3500HD DRW's towing the 38' Mobile Suites in Colorado and New Mexico and the trip from Tennessee and the return total miles 6,850 and over some 9 thousand feet in elevations..

As for hand calculation or using the DIC my 2011 and 2012 Chevy are within a tenth. In the past I never kept up with fuel mileage, but when I went back to the 1 ton GM trucks in 2011 I did check the mileage. I think it could be better but considering I'm towing a square box down the road the mileage isn't to bad. EPA is the cause of the fuel mileage issue.... Happy Trails.....
