A couple extra blocks. We had trouble side to side and front to back. Tried not to unhitch but that wasn’t possible. There were a fair amount of pull-throughs with a couple of long ones, but they are wavy.
We visited in March of 2019 and it's true there is not a level site in the park. However most look to have been usable with three or four inches of adjustment. We took the long pull through site directly behind the bathhouse and did just fine with our 28 foot trailer.
We read about unlevel sites but were up for a challenge and based on the location/timing of the day, Jeff Busby cg worked great for us. We were able to find a site to accommodate a 30' Airstream but did unhitch for the night to level front to back. Go for it!
