We were just there in September. Road surfaces are decent but roads are windy. There is a tunnel somewhere on Skyline Drive and I found conflicting info on it's height. Some sources said 12', but I think I read 12'4" elsewhere. Its a great area and a great drive. We set up our trailer at Misty Mountain Camp Resort in Greenwood VA, and then drove parts of both the Blue Ridge and Skyline in the truck.
We would go back to Misty Mountain. Had an issue with one of the 50A breakers, but even at 7pm on Friday night someone came out, he didn't understand much about the Progressive EMS and why it was cutting the power. Said he would be out in the AM and change the breakers, wasn't hot so it just ran off the 30A for the night. Next day we got back to the trailer it was plugged back into 50A and line voltage was good. Sites are a bit cramped, but we were out and about and didn't spent much time in the campground so it was pretty much a non issue.
