I have an '11 Duramax with the 3:73 rear end. I pull a 10K 5ver. I get an average of 10 to 10.5 at between 60 and 65 mph. The speed puts me in the heart of my torque power band. I get between 18 and 18.5 empty at 80 mph.
My buddy has a Dodge with a Cummings and I have always gotten better MPG than him. IMHO , I think you're doing fine. You might do a little better if you find where you peak torque is on your power band and just set your cruise there.
