We had a difficult time backing into our spot as Class B van. We were passing through Bentonville- Fayetteville, and the State parks and USACE campgrounds required Friday + Saturday night reservations.
The loops are on pretty step hill sides. There were a few class A's there, but I am not sure how they got into their sites. Many campers appeared to be long term. The class C next to us had a deep freeze freezer outside their unit.
