The road in the campground has some tight turns and is narrow to get to the campsites But is very doable. Another great campground up that way is Cloudland Canyon State Park which isn’t as tight to get into.

The road to the park has steep inclines/declines, twists/turns and is narrow but many RVers take rigs larger than yours to the park. Take your time and make sure you drive the road during the day and you will be fine.

We have a small truck and a 19 foot camper so we had a difficult time pulling it up the mountain. But, a C class should have a stronger engine and be just fine. Have a great time!

I can’t really answer with any confidence as I have never driven an RV. We have a very small pull behind camper and while the roads are somewhat narrow they are well maintained and we had no problem. I would make a general comment that if you are comfortable with size of the RV while driving I would think you will be fine. Sorry I cant be more helpful. Enjoy the trip. Lots of great hiking at the park
