The map shows 4 sites with a maximum of 50'. I would call the office to verify. I can't imagine there being a limit since it is mostly all wide open space. We stayed there once but weren't too impressed, just FYI. No privacy, bath house was so dirty I skipped the shower altogether and hated to use their toilet.

The pads are big. Especially the first 5 or 6 sites. We stayed on #3 last year, plenty of room for our 30' 5th wheel

I don't have a campground map with me, but am certain there are a number of sites that would work for you. I don't recall a Class A when we camped there, though there were a number of large 5th wheels.
