If you have a RV Site can you put tents down as well?

Yes, but I would make reservations over the telephone. They can help you find a site that will accommodate your RV and a place for the tent.

It all depends on where and what kind of site you're going to be staying on. If you want a site That can accommodate both, then you will have to let them know what your plans are for the site. Just like suzanna had mentioned. Call and let them know and they will help you out in anyway they can.

For long term stay no. Weekend or week campers yes.

Yes you can.

Tent will be on asphalt

Yes, I know they charge the same up to four people, anything after that is more.

Yes, although they may charge more. You will need to check.
