First trip in Class A driving in Smokey Mountains

I agree with other's comments and it sounds like you did everything right, especially going down hill and not letting your speed build up and get out of control. I never worry about slowing down going up hill as I know there is nothing I can do about it and put on the 4 way flashers when under 45 mph. In the mountains out west, often I may end up following a semi who is also slowed down by the up hill grade and I usually back off a bit on my engine RPMs as it can be many miles to the top.
