We were there last weekend. It is a great park. We stayed in site 74 in the south loop with a 35' travel trailer. This site was pretty level as i didn't need anything extra to level the trailer. This is the only site (I Think) that you can actually see the lake.
From what I hear the North landing sites are very unlevel and many sites in the south loop are very short. If you use the online reservation site it will tell you the site length.
One BIG issue with this park are the ticks. If you go into the woods be prepared. I thing every member of the family had at least one and we were being careful.
