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...

I have a 2015 2500HD with the 6.0 gasser. It has a love affair with gas stations. Got a whopping 6.7 MPG on average on our last trip. Have never seen the 8-10 MPG others claim to get while towing. I get anywhere from 9.3-9.7 MPG with nothing in tow! The Tow/Haul mode isn't all that wonderful either. Plenty of times, it's failed to downshift the engine after cresting a hill. Sometimes I'm a third of the way down the other side of the hill and the engine has failed to downshift and is still screaming. I've had a couple of instances when the LCD display didn't work and had a black screen so I had to adjust radio volume etc. from the steering wheel controls until I could stop, turn the truck off and then re-start it. Also the backup camera hasn't engaged the LCD screen a few times and I've had to put the truck in Park and then back into reverse to get it to work but other than that it has been an OK vehicle. Of Course, when brought in to have these issues checked out, nothing wrong can be found. In the end, it's an OK vehicle but nothing to write home about.
