I tow 23k with my 15 RAM with 4.10's turning 1,750 RPM's @ 60. My combined weight is 33k. I get 9mpg hand calculated towing at 60 mph. This is West coast where I can be as low as 7 or high as 10.5.

I was wondering if you would chime in as I know you pull pretty heavy.
Not sure what the specifics, rpm and such were but when I towed my 16.5K toy hauler, my Ram was getting around 11mpg towing. To me 6.6 seems a little low but then I don't pull any faster than 65mph for an extended period of time.
