I just drove this 2 weeks ago. Reading on this forum, I almost talked myself out of it but I'm really glad we drove it. I have a 35' fifth wheel and a diesel gmc 2500hd.
My thoughts:
- Yes, there are drop offs with no shoulder. BUT, the speed in those sections is 10 mph. You are going really slow. The hairpin turns are 10 mph - 15 mph. Again, the posted speeds match the conditions really well.
- People will poo poo the road, but they determine that based on their vehicles, their trailers, and their experience. I would not want to do it with an undersized truck but a good setup works just fine. My diesel truck did very well. You determine yourself if your setup will do it.
- Engine brakes are good, down shifting is good. Pulling over to let people pass is good. Experience on windy roads is good.
- It is beautiful!
- We drove it on a Sunday afternoon and traffic was light.
- There was a fugitive in the area when we got to Silverton. :) Really, they had a flashing sign not to pick up hitchhikers. They caught him later that day.
