I get 10-12 mpg with my 6.0 diesel when at 19K lbs GCW. Through the Rockies was closer to 9 mph. I don't drive it enough unloaded to give you highway mileage, but local runs to hardware and lumber stores usually net around 15 mpg. Engine and transmission is stock with no tuners or emission deletes.
