Audra state park

We are headed out in July to Cherry Hill in DC, then to Liberty Harbor outside of NYC. We’re wanting to unwind on our way home in West Virginia. I’ve found Audra state park in West Virginia which is about half way between NYC and Cincinnati. Looks like a great state park, but I have two reservations concerning the park. 1st they don’t take reservations, were be arriving on a Monday and staying until Thursday, so I’m hoping they are not full. 2nd the sites look better suited for tents.
Does anyone have experience with Audra, and if so do you think we would be ok mid week in July with a 28’ TT?
