Stock 2015 F250 6.2, 3.73 gears with XLR 3016 TT around 9500lb TT in Central/Southern Ohio. Flats and some hills, 65-70 mph 6.5 mpg. 5th locked out, auto on the flats, manual shifting on the hills. This past weekend, no wind to speak of. Wonder what I'm doing wrong...

I did the first trip with my 2019 F250 6.2, 3,73, towing a 5800 lbs trailer from Reno (NV) to the Central Valley of California and back. Even going "down" to California you have to go over Donner Pass, and the whole trip has a lot of hills where the truck had to go down to third gear to keep the speed.
I had 11.9 mpg going and 8.5 on the return trip, for an average of 10.2.

Perhaps if you understood where the torque and powerband of your engine is, you would understand locking out 6th gear. Nobody said anything about 70 mph. The software for the tranny is designed to put it in 6th gear and towing heavy loads around town does not require 6th gear, or even 5th sometimes, if you want to get the best mileage and driving performance. I speak of the 6.2 and I see many of the 10 speeds suggest locking out 10 and 9th.
