I have had a CDL since 1974. I have driven almost all types of vehicles and combinations. My 2010 Ram 3500 4x4 Cummins that has an exhaust brake which I use when solo or when towing my 39 ft Keystone Alpine FW. If you have balanced your TV and trailer, I would not increase the braking on the trailer if it has the drum brakes because of slower heat dissipation in the drum brakes vs the 4 wheel disc brakes on the TV. It is very easy to overheat the trailer brakes when going downhill. If you have a gasser then I would decrease speed and use lower gears. BTW I know a guy that has a 2014 GMC 2500 Duramax that brags about never using his exhaust brake because he is a great driver!!
