Michael, Good advise from all. Best suggestion was relax. Many of us have been all over the country west to east, north to south, some of us have a lot of miles under our belts some not so many but regardless I can't remember the last time a member reported going off a cliff. I have a jake in my bus and have gone up and down some serious grades with very little pucker up factor involved. As stated leave the jake on high and stab the brakes as needed to maintain a comfortable speed and don't worry about holding up cars behind you. They'll get over it. Some of the best scenery in the country are on roads and highways that are not the best suited for our buses. But if your like a lot of us we bought our buses so we could enjoy those areas.
