Same truck , when coming down a hill I turn off the tow haul as I do not like it shifting for me , tends to really get the revs above what I like . I will shift manually , maybe it is just me .
The higher the rev the more braking HP the exhaust brake is able to make. I Towed 24,500 combined with our 2015 and descended mountain passes in TH and full exhaust brake, then selected the gear required to hold back without using service brakes.
If it slowed to much a little foot on the throttle turned off the exhaust brake until speed went to the point the exhaust brake was needed again. SO your throttle foot allows you to be in control of your descent along with selecting a lower or higher gear as required.
Towing out West one gets a lot of opportunities to practice the skills of descending a pass without using your service brake. Which gives you nice cool service brake if they are required.
