The OP asked, "What does the future hold for 55+ park model communities?"
To survive and make money, I think many parks will follow the lead of some mid-level parks in South Texas. They are relaxing the age requirements and allowing younger people to share the RV park lifestyle. Some are still employed. Swimming pools, exercise rooms, recreational halls, clean bathrooms, relatively safe streets, and low rent must seem like Heaven to many. Look around the park community and you will find a lot of people who do not have nearly as many amenities.
Therefore, my answer to the question is, "Move over folks, there are others who want to enjoy what we take for granted". With park models aging and becoming cheaper, more people can afford them. Not as a second home, but as full time residences. Look for a school bus coming to your park soon.
