2017 2500hd 6.0 gas up-grade questions
Getting my new truck Monday. Double cab, short bed. Has all the bells and whistles. Tow a 13,880 lb total loaded weight with 2880 lb pin box weight. Besides adding mud flaps, is there anything that...

dave, I tow a 2014 27RK Heartland Trail Runner. Loaded it's about 8500 pounds. As for speeds, I go the speed limit. If it's a 55 zone, that's what I do. If it's a 65 zone like on the Thruway or Interstate, I'll do that but much of the time when in a 65 zone, I'm going 60ish if I have the cruise set and I'm on any kind of uphill grade. Like I said, even when I'm not towing, I get an average of 9.3-9.7 MPG and at my age, I'm not driving it hard. I have a buddy who has a 2013 GMC version and he gets about the same with his truck towing his cattle trailer that's about 8,000 when loaded.
Somethings wrong to get that bad of mileage. My truck at work is a 2015 Chevy 3500 4wd with the 6.0. It has a big tool box bed and ladder racks. It's always carrying enough tools and guys to weigh between 9,000 and 10,000. It averages around 11.5 to 12 MPG and that's with 4.10 gears.
