This has nothing to do with being snobbish. It's 100% about keeping trailer trash out and political correctness. If the RV parks could, they would have a policy that says, "No piece of******junk looking hippy busses allowed in this park." But that is not politically correct. So they say no rigs over 10 years old because when was the last time you saw a piece of******looking hippy bus that was newer than 10 years? And like others have said, they waive their ten year rule once they've seen your rig, as long as it isn't a piece of******looking hippy bus.
