There was a site on the end of the run near where we stayed that was accommodating a huge class A which I am sure would be suitable. Maybe check the sites out on Google Earth and then request what you want way in advance. I wouldn't rely on their assignment of sites based on your length. I barely got into my site and had to park the truck under the bedroom slide as there was no other room. I also had to tie back the branches on a tree to get in the door. If you are going in the fall bring rubber boots as the CG really puddles up when it rains.
