You need to put the info in the Amenities/Features box for the parks that don't allow RVs older than 10yo. Not everyone trades in their RV every 3 or 4 years like they are cars. These parks like to not put that information out and that means I either show up and find out or I sift thru every page and tiny link to find the info. I don't stay at 55+ parks, it doesn't matter how old I am. And I don't stay at parks with RV age restrictions, it doesn't matter what age the RV is that I would be traveling in for that trip.
