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.

Is that gas station to gas station hand calculated? Or rolling on the freeway and reset the DIC? I've towed between 8k and 10k bumper pulls with several diesels and only get above 10 mpg under 60 mph. Most of these were tuned and no regens. I track everything in an app so everything is hand calculated every fill up.
