Where are you looking for the restrictions? I have never seen a park that had odd restrictions that didn't post them on their website. If you are just looking at a camping guidebook, those listings are provided by the book publisher and the campground has limited input into those ads. To get out more information they need to buy ads, and when you buy an ad, you tend to put in information to sell your product, not list the restrictions, since space costs money. The best bets are look at the park's website and call.
