Added info to my sig, I think.
The Duramax is incredible. I ran about 70 MPH all the way to Michigan and got 19 MPG, still had a quarter tank left after 500 miles. The mileage on the way back with the trailer was about 11 MPG. The truck still ran 67 MPH at 1500 RPMs, like it wasn't even trying, but the extra 9,000 lbs and huge wind drag kill the mileage. I am more impressed by that exhaust brake than the towing power though. It slows the entire set up without having to barely use any truck or trailer brakes.
