We arrived today and found out they do have propane at the checkin station!

No propane is available at Oak Mountain. We went to an RV park not too far away from the campground that does refills. I believe there are Tractor Supply and U-Haul close by that sell propane.

I don’t think so. But, I’m sure if you online search you will find one within 30 min. I got a tank filled in the Oak Mountain/Hoover area so I know it’s available.
