I don't know if I did it right, but this should give you the campground map from reserve america. We have been to the campground quite a few times and we loved it. We stayed in F loop. I think they call it Fox now. Some of the sites we liked were 36,38, 40 and 41. They are fairly level and and large sites. You should have no problem with a 30 ft er. I have a 30' fiver. This is the only loop with full hook ups.
They do have a few sites overlooking the water. I have seen some nice size trailers on them. There was one we really liked. but it had no hook ups at all. I need to refresh my memory to let you know where that site was. If you need more info don't hesitate to ask.
We took the boat up there and kept in their marina. It was just over the hill behind site 38.
