Economy mode on an Allison Transmission
Does anyone know if there is any benefit to turning on Economy mode while using cruise control on a highway? If I've got the cruise control turned on at 64 miles per hour, will economy mode help? ...

Even at it's best, the most you would ever see is maybe a .5 mpg increase and that would be on a rare occasion.
To truly get your average mpg on a motor home, you have to average fill ups over several thousand miles.
I was using the vehicle computer for average economy. I reset it and drove the trip. Then I repeated the process for a longer trip. The longer trip had more hills so it wasn't a perfect comparison. From the vehicle computer it seems that does make a difference. Oh and the terrain wasn't completely flat there were overpasses.
