I saw a show on cable (HGTV, perhaps?) about a trailer park in Malibu where the trailers sell for over a million dollars each. The trailer park is on a cliff overlooking this beautiful beach and there is easy access to the beach, even though you're on top of this cliff.
So there, you are paying for the view, location, and beach rather than the actual mobile home.
The mobile homes are very swank as well. All very well trimmed out and well maintained, they aren't "mobile" at all.
