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

I can not speak of all 65ish people

my wife barely made it to retirement... and must escape the Cold to breath..
I retired early with back problems.. after 4 operations.
We Both worked most of our lives.

so we are starting to look at a park model.. and stay south ... full time.
a 30x8 foot trailer is to small..
and $50k is way out of the budget..
