Did your see this info from both the forest service and rec.gov sites? "Site #1 is set back in the trees and although not too large, is very nice. It is 40 ft. by 30 ft. with rough road access. It is suitable for a single family, but trailers are not recommended. Swimming from site #1 is not recommended. A primitive toilet is located at this site and is shared with those using the boat launch. Site #3 is an excellent camping area at the top of a small, sandy bank. It is an open area 100 ft. by 70 ft. in size. The access is good and this site is suitable for two families and trailers. A primitive toilet is located at this site. Swimming is good, however the shoreline cannot be seen because of the high bank. Site #4 is located on the south side of the lake. This site is 70 ft. by 45 ft. and can accommodate one family. The access road is firm but very narrow with sharp turns. Trailers are not recommended at this site due to very limited turn-around space."

I don't think the information Wandering Pulse is referring to is up to date on the website. This site is absolutely massive, and yes, we do have a van, so I didn't pay total attention to tree clearance overhead, but I would imagine you could fit through the turns and find a decent spot in just about any sized rig. Sites #3 and 4 are much more open, and not terrible, but not nearly as good as #1.
