I was using Tow/Haul. Now that I think about it I might not have ever slowed the truck enough initially to allow the engine to maintain the speed. I was worried the engine was working to hard. I disengaged the tow haul a couple times to allow the engine to slow down. Again this was our first trip and I am very inexperienced towing. I guess I am saying I didn't trust the truck to do the work in fear of over reeving the engine.
NEVER up shift on the down grade. the engine will hold you back and save your brakes. You will NOT hurt the engine by letting it do it's work. Now. IF you want to go even slower. Drop to first. Find the gear that will help you hold the speed you need. and yes you will need to tap the brakes every once in a while. But you should not need to ride them. Use your gears. That is what they are for.
Also. As mentioned. It is a gas engine. So it does not need a exhaust brake. Gas engines do naturally what diesels need exhaust brakes to do for them. Create engine braking.
