We stayed at site 34 and had booked for an RV and a trailer, apparently this is not allowed, even though recreation.gov let me book it with both equipment types listed. The camp hosts were very gracious about it and even found us a new spot from people who were leaving early (I think it helped we had kids, they took pity on us ;) The vault toilets were very clean and spacious. The sites were a bit close together, about half were exposed, no tree coverage, and the other half were provided ample shade with lots of trees. Site 34 ended up being perfect for us because it was right next to a little forest and the kids ran around in there a lot, which they loved.
