A data plate is simply a piece of paper inside the mobile home that looks like a map of the United States on part of the paper. These "data plates" are located on the inside of kitchen cupboards, on the walls of walk in closets or sometimes on the inside of power boxes. Sometimes they have been removed from the home by owners who simply do not understand what they are. The information on these data plates illustrates information about the roof, walls and wind zones of the mobile home direct from the manufacturer. These papers can provide a lot of great information so they should be left in the mobile home.
