Firearms in RV

I did call the state park and was told that NO firearms were allowed in Arkansas State Parks. This seems to go against Arkansas Law that I've read. I do carry, but this question was for her. Most LEO'S look out for one another, but there are rare occasions where they don't. She's a shorts and tee shirt girl and doesn't usually hide her gun when walking from a hotel room to the truck. It's not an issue in Louisiana and we have no issues open carrying in Louisiana State Parks as it's legal. Just wanting to see if anyone else has had an issue in Arkansas. I think the State Park rep needs to be updated on their state laws.
