We are changing from 2003 Chev. HD 2500 Duramax. Was happy with the old milage, anyone know what we can expect with the new truck? It is GMC same set up,only this is 6600 High Output. We got 17-20 mpg on the highway with our 03, and about 12 when pulling our 3400RL Montana. Would appreciate some feedback on this. Larry and Pat Olson
