Is this a campground that’s open all year long and has power and water hook ups for a motorhome or tiny home bus?

It is open only 6 months out of the year. It is currently closed for winter. It does have hookups.

It's closed after labor day until April

Not open all year. It absolutely has hookups. I saw many RV'ers there. Trailers and VW busses as well. The facilities are clean and easy to use.
