We stayed at Bull Run Regional Campground on our visit to Washington DC. It was fall and the colors were gorgeous. The sites are all pull-through off the roads through the campground. So your camper faces the woods and you feel like you're all alone. Bath houses are clean and well maintained. Our site was very level, but I could see that some others were not so much, so you might want to ask about that. The staff was very friendly and helpful.
