I’ve thought about locking out gears too. My assumption like you would be that the transmission logic would be to keep boost low but that appears to be incorrect in practice. I’ll try it our next trip.We get between 10 and 12 pulling our 23 foot travel trailer. I've gotten up to 15 before but that was going an average of 55.
I also lock out a couple of gears on the transmission to keep it out of boost and have the transmission do the work instead.
