A lot of mobile homes aren't actually that mobile. They're brought in trucks in big pieces, then screwed together and put up on foundations. At that point they're basically just houses, with one major exception: the people who own those houses, if they live in a mobile home park, often don't own the land underneath them.That can leave them at the mercy of the big companies that own and manage the mobile home parks.NPR's Chris Arnold and Robert Benincasa have the story of a group of residents who are suing their corporate landlord, and what it might say about the mobile home industry in America.You can read an in-depth version of the story here.In participating regions, you'll also hear a local news segment to help you make sense of what's going on in your community.
