I have a camper that I plan to use but my parents only have a tent. Can they set up on my RV site?

No they wont allow tents on sites with RVs, you have to rent another site.

Im not sure, but dont see why not if you've paid for the rv site

The rules state that rv only no tents but you can call them they may allow it

Yes

Totally separate sites and locations.

Thank you for the help

They have done it in the past you just have to call and let them know and pay a small fee
