unless you love the smell of your brakes, SHIFT DOWN SHIFT DOWN SHIFT DOWN!! It amazes me how this is not obvious to people, even just in cars. We came down Pikes Peak (not towing of course) and there are signs everywhere to use lowest gear. Yet when we hit the mandatory brake check, people get pulled off and told to stop and wait for 20 minutes because their brakes are too hot. Me, she looked at me, chuckled and said "you've done this before - keep it up for the rest of the way down!" I wish I was a native. Enjoy!
