Just happened to think about this... when on our trip, and making reservations by phone, we were often asked how old our trailer was. We explained what it was, like home built, modeled after the 40's style tear drop, etc.... never understood why we were asked..
Then, at one campground, we ran into a fellow with a nice older motor home parked in a back corner. Turned out they didn't want to let him in at all because it was over 20 years old. Never realized campgrounds had 'age discrimination'.
So, was wondering if anyone else had ever heard of this, or been affected by it?
