2015 2500 duramax fuel mileage

[Tar]

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 some small hills?

Thank you for the replies I like the thought of going to a 3500, might want a bigger camper down the raod

My Duramax gets about the same as the others. I would look into a 3500 not much more money if at all and a lot more payload. Leaves options open down the road. I went from a 2500 Short Box 2 @ 3500 long box and have been very pleased. For me mileage was not nearly as big of an issue as the pure fun it is to pull with a diesel. It just feels great going 60 mph at 1400 rpms, up and down hills without changing gears. But then there are the issues that diesels have being a more complex motor with modern exhaust def requirements. Also I have read alot about potential costly fuel pump repair. Like 10k worth. I myself had def issues a couple years ago but the dealer took care of them and I haven't had any issues sense. But I do LOVE my Duramax.



Just my humble opinions

I can achieve 20 hwy not towing. 9 to 11 towing and around 16 everyday driving. My average for last 20k miles per DIC is 15.4 which includes abt 2000 towing miles.

10 towing maybe 17-19 non towing
