2015 2500 duramax fuel mileage
I am thinking about upgrading to a 2015 2500hd duramax to pull my 34' 9600# fifth wheel from my current 2500 gas truck and wondering what fuel mileage to expect pulling in mostly flat land travel with...

We have a 2012 D/A crew-cab short bed and pull a Jayco HT 26.5 RLS with a 19' Crestliner behind the FW. When pulling this combo from Lander, Wyoming to Jackson Lake in Grand Teton National Park and back, we get between 11.5 and 12 mpg. One trip we got 13.6 but only that one time. Traveling at 70 unloaded we get between 18 and 19 mpg. Depending on the hills and mountains you travel through, I would think that is about what you should get, if not a bit better if you are closer to sea level, we live and drive at 5,000' altitude and above.
See what I mean... Same year/model truck with vastly different towing mileage. 8.5-9 vs 11-12mpg.
IMO it's more about the luck of the draw and what you happen to drive off the lot with.
