On a 2016 Ram CC dually, 4:10 gear, Aisin, with 1200 miles on the clock pulling 16,500 going into a 30 MPH headwind at 65 MPH at 100+ degrees the water temp would go to 3/4 on the gauge, the oil temp would be 3/8 inch above center and the trans temp would be 1/4 inch above center, then the fan would turn on and everything would go back down close to center and start the climb again. Also the trans would not hold 6th gear and would hunt 5-6 if using cruise, had to go to foot pedal to control that, then it would hold 6th. That's my findings on our first trip. Hope that helps!

In those conditions you may find locking in 5th will net better mileage.

He will NET better if he would leave the cruise off and drive the truck. Let it creep down a little on the up slopes and creep back up on the down side. This is the problem with the power wars. Everyone wants to run like they are not even pulling something. Our OEM are making these trucks with big rig power but are still using passenger car cruise programming. It's reaction is way too slow to keep up with the weights we are towing. My service truck only weighing 12-13000# will gear down on the interstate running 75 MPH on cruise not towing a thing.
