Have dealt with this. I own a 2007 RV. Maintain it well enough that it isn't an eyesore, but I'm not going to waste my life on upkeep. I have never been turned away from an RV park in the last ~6 years that I've owned it, even when staying at "must be 10 years old or newer" camp sites. Like you said, it's more used as a policy to turn away. People who the park doesn't think fits their vibe.
