Hi there!
Well, you will get all kinds of answers. You have to make the choice based on your comfort level. Have driven it many times and would never recommend it for most RV's....simple as that.....teep grades, tight turns, Hogback area has no real shoulders with no guard rails and steep dropoffs.
Mountain Directory West will give the intensity of the grades but does not mention the little to no shoulders, no guard rails, etc.
That being said, make sure to drive it with your toad. Bryce and Capitol Reef are two of our very favorite places and been to both many times.
Remember, you can have control over everything except the guy coming the other way.
Email or PM me if you would like.
