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? ...

We have a 2014 Thor Palazzo with an Allison MH2100 and a Cummins ISB. With the mode switch on and on flat ground with the cruse control set I was able to get 15 MPG. With the mode switch off I was at 12 - 13 MPG.
