We went up with a 40 ft dynamax dx3 towing a jeep. Some would say difficult "yes." In my opinion, its nerve racking but very doable. Take it slow and dont look down! Lol. Call ahead to check that you wont need tire chains on the way up. I'd do it again if I ever had the chance. No Short Cuts! Ignore google. Stay on the main road and you'll do great.
Dr Buckber did it. I have not driven a RV so I can't say.
