OUR 15 dually with asin and 3:42 pulling a Landmark at approx 17500 at 70 gets worst mileage in 6th at 1650rpm then pulling in 5th at 1975 rpm.Best mileage is keeping it under 70 and 2000 rpm,seems to tow best at 68 with few downshifts
My 14 does too if I am towing 70 mph or below. I was amazed at the fuel mileage difference between the two gears. I thought it was be less than 1 mpg, but was surprised when it was more than that with both my gooseneck cattle trailer and 5ver. In fact, it tells me to use the ERS to select gears to lower gears for optimum performance/efficiency and to extend the transmissions life under tow tips in the owners manual.
