What does the future hold for 55+ park model communities?

We are in AZ this winter for the first time. While looking for parks, we eliminated any park with over 200 sites, any park that had more than 50% park models. We want a campground atmosphere, not trailer city. We cannot imagine anyone wanting to stay in a field, surrounded by a fence with barely enough room for an awning between you and your neighbor. There is more to life than that.
