It depends on the site you select. You can filter so only the sites that are large enough show up. Or you can just look at what sites are available (in the reservation system) and you'll see the following for each site... Allowed Equipment Tents Truck Camper Trailer or RV up to 20' Trailer or RV up to 25' Trailer or RV up to 30' Trailer or RV up to 35' Trailer or RV up to 40' Trailer or RV up to 45'

I would say yes. They have some pretty big sites and their descriptions are pretty accurate. Pay attention to the available site pics weird tree locations. The trees there are typically very tall with very few low branches.

I would say some of the beginning sites MAY be but there's a LOT that wont work. I'd recommend to call and ask.

Yes. There were many Class A’s when we visited, some sites are larger than others. I would call the park office directly to get a ranger’s advice on the best spots for your rig.
