When trying to reserve a site at rec.gov it says 18 max TV. Is this true? I could have swear I've seen bigger rigs camped there.

Did you ever find out about the 18' max on trailer?

I don't see anything wrong as I camped with my tent trailer with two vehicles. Plenty of room. I suggest you to check with the campground office. Good luck and enjoyed this place

This is the recommendation, but my dad's truck and rv are combined quite larger and fit into these spaces with ease. Although it would benefit you to look at the spaces I think there's a space map online, and from there choose a space maybe with a pull through or further spaces from neighboring sites.
