I've spent a few shoulder season nights at Barview, usually in the early-mid spring. At that time of year, you have a good chance of not having immediate neighbors. I stayed one night in the RV section, and don't think I'd enjoy it on a packed summer weekend. The RV hookup sites are really close, with no trees or other screen between trailers. The good news is that everyone has been super friendly whenever I'm there. 

The tent sites are much more private with trees, though there are still a lot of sites. I think we paid about 50 bucks to camp in our van with our dog, though. At that price, the value just isn't there for me.
