I have 7k miles on my 2022 Crew Cab Elevation Duramax. I drive all highway miles and have averaged 25mpg, but I’m usually going 80mph plus. I just did some towing and got 20mpg. I was very happy with that. Powerful little engine. No issues at all towing. First time towing with a diesel and it was like there was nothing back there.
