There used to be one near the Orlando Intl. Airport. I remember it from seeing it three, maybe four years ago.
You might want to try going to a book store. There are RV and camoing guides that cover the entire country by region. It should have information in there that can be of some help to you. However, keep in mind that you will be most likely looking for an RV that has all the pots and pans in it too, that may be a problem.
