That’s a diesel - talking about gassers in the HD series and their wonderful fuel mileage.  I’m not complaining, just the way it is. 

Getting 20-21mpg hwy with my 2022 Ram 2500 Cummins MegaCab. 30,000kms on the ODO. 

Ya, my 6.4 in the dodge ain’t winning no fuel mileage competitions, but what is in a 3/4 ton truck.  It’s pretty crazy the difference between a 1/2 truck and a HD truck.

I need a 3/4 ton for work. But I have decided to keep my 6.0L    I know a guy that has one of those 3.0L diesel’s and it’s phenomenal on fuel. I wish I could say the same about my truck lol

Just an FYI. If you dont need a HD. Buy the baby duramax. Mine is phenomenal with fuel consumption (better than most cars) and It will pull a hell of a lot
