There are too many variables when it comes to MPG. I have a 2019 3500 Duramax-SRW. Our 294 RL Monty has a GRWR of 14,300-it usually weighs in around 13,300 when loaded. (Pin weight is 3000 lbs).

I’m happy if we can average 10 MPG. Throw in a stiff headwind and I can see 7 MPG. This is at an average speed of 65-70 MPH. Real world numbers, can’t believe anyone would get mid teens pulling a 13,000 lb (plus) RV. It would be interesting to know if the new Allison tranny improves MPG. It’s a bullet proof tranny.
