Is there, or can we bring our own, a small fire-pit that we can sit around drinking hot chocolate and cooking smores?

Agreed, I know you can grill so I would assume a fire pit would be allowed.

I'm not 100% sure about wood fires at Fredericksburg RV Park, but we bring our own propane fire pit to many RV parks and it is usually acceptable. If there is nothing in their rules online I would simply give them a call. P.S. It is a great RV park for sure.

Neighbors have a small metal pit for wood burning campfires.
