I agree with the comment from WanderWasi - this campground is generally not made for large rigs and is heavily wooded. There are definitely sites that will work for you, but be selective and careful when making reservations.

I wouldn't say most, I would say about half. If you check the reservation website, it will state max length for each site. I wouldn't push it on length because the sites are pretty tight with trees or directly off the side of the road. We had a 40 site pull through site with our 30' and still had to back in because of trees. Have fun!

Yes, it would fit!
