Anyone been turned away from campground for older rig?

There were a couple of RV parks here in the Lakeland, FL area that also had age limits on the RV's. One park even turned away a 15 year Prevost that looked better than a new one. Thank goodness that one is now closed and replaced by a shopping center and the other one now has new management. The real kicker is that both parks had a few Old (like 20+ years) Travel Trailers sitting on blocks further in the back that were occupied.
