Differential upgrade mpg pain

[Danz]

I bought a 2022 RAM 1500 4x4 with the 3.6L 6 Cyl. eTorque, tow packages and differential upgrade to the 3:55. Towing my 6500 lb travel trailer I was unpleasantly surprised to get only 9-11 mpg. More unpleasantly surprised to find the computer says I’m only getting 11 mpg empty. Can’t be right, right?

My TRX has 400 HP more than your Pentastar V6 with the same gear ratio and I get 11.8 MPG. You should have bought a TRX. 🤣

One thing I’ve learned over the years is if you are towing a camper with a gas engine you are going to get ~10 mpg. Don’t care it’s a truck, suv, v6, v8, turbo, na, 3000lb, 6000lb, always seems to ends up around 10. It’s more about the huge windsail than weight.
