I am starting to wonder if I will even need any special driving techniques for the stretch I'm thinking about, between Cheyenne and Laramie on I-80. Westbound, going up is very gradual, but down is roughly 5 miles of 5% grade. I have been up and down it hundreds of times so I know it quite well. No sharp turns, much less switchbacks. Driving a car, even going down I always have to apply gas just to keep up to the speed limit. Will a 27' class A Winnebago really be that much different? I also drove it frequently in a Fleetwood Jamboree class C (25'?) and never had a problem going either up or down, although I don't remember if I had to apply the gas pedal going down.
I'm planning a shakedown overnight at a state park about 15 miles away. Higher up in the mountains than our home location, but it's not steady up or down; the state road twists and turns and goes up and down. Again, I am VERY familiar with it so no surprises, and also drove it in the class C.
I'm sure I'll wind up on steeper roads that I'm not familiar with so I'm still following the thread. I also went looking for the Mountain West directory and discovered it's available in app form for $35. Has anyone used it? If it works as well as the book, it would sure be more convenient to take along.
