I haven't been there, yet. My trip is in August. But I will say this, start booking and soon. I found that there wasn't a lot of open sites available and that was a month ago.
We are at Ellsworth AFB now not too far from Mount Rushmore. We went there a couple days ago. The road to Rushmore goes through Rapid City, SD. We drove through Custer State Park to see the buffalo. Very windy road with one lane tunnels. Plug it in your GPS and enjoy the view.
We've done trips similar. There's not a lot of places you can't go. We went through all the winding roads in S. Dakota from Mount Rushmore without issues. Roads into Yellowstone are okay as well. I only had a little trouble with a campground in Sequoia, I don't remember the name, it was smack dab in the middle of the park. Short winding roads in the campground lined by curbs. We had a 34' 5th wheel at the time and made it out alive. Just use common since when traveling on hills/mountains.

We just got back from the Black Hills. Gorgeous area, but I would avoid Rapid City. Highway 44 was under construction, with a good size drop off on one side and narrow traffic on the other. We came home thru Deadwood on #385 connecting with 14 to I- 90 and had a short construction area, but was not as bad as Rapid City. We were there a week and tried to do it all from zip lining at Rushmore, renting a pontoon boat to driving around the sturgis area. A lot of motorcycles were coming in for the rally and a lot of businesses were busy in preparation for the 75th rally. We LOVED everything about that area
