I have a 2008 Chevrolet Silverado 2500HD Duramax and just completed a 1760 mile drive from Rio Hondo, TX (Winter Texan)here to my home in WV. I averaged for the trip (vehicle completed loaded, mostly bulk) 18.4 MPG. My driving speed was the speed limit plus 4 or 5 mph GPS. The fuel mileage remained the same from the 45 mph hi-ways up to the 80 mph roadways. The LMM series is where they loaded the vehicle with the DPF and converter, every time the DPF regenerates it drops my mileage by 2 mpg for the tank so the mpg suffers during short trip driving. The vehicle has 98K on the odometer and I may address the regeneration issues in the future.
Keep that pre-emission Duramax until it rots off of the frame. IMHO
