In the state park you're limited to two periods. If you can find a spot that is open and alternate two week reservations you might be able to stay for a while. Many of the weekends book out nearly a year in advance. Coal country camp ground in a couple miles away but not sure of the amenities.
There are long term campgrounds in the area, I don't believe the state park is long term, and I don't believe there are any that are full hook up.
If I'm not mistaken, the longest you can stay is 2 weeks then you have to pull out for a few days.
