With the truck and TT in my signature I average 12.5 in the mountains of Colorado. I am not sure how much towing on flat land would change this.

I just got back from a 2555 mile round trip to Florida and averaged 21.7 MPG. No trailer this time but, when I am pulling my 15000 LB RV I get 12-13MP.
I am very happy with my results.
