Thanks for your responses. I have a 2020 Chevy Silverado 3500HD diesel dually, pulling a 40’ Montana High Country. I do have the exhaust brake and tow/haul mode on at all times when I’m towing.

I have had no trouble taking any incline I’ve been on so far — in New Mexico, Arizona or East Tennessee. Haven’t downshifted on those inclines that I recall, and it seems like the truck handled them with ease. If I felt like the truck was straining, I believe I would have slowed down and downshifted.

I have NOT, typically, slowed my speed at the top before descending; I realize now that’s part of the strategy. As I pick up speed, it bothers me to see the RPMs climb as the engine tries to slow my speed. It seems obvious that if I start the decline at a slower speed, the RPMs won’t climb so high. Or maybe I shouldn’t worry about it. Is there a point at which I should worry about RPMs?

Thanks, again.
