There are lots of rural areas in north central Florida where you can keep an RV at your home. Not the fancy retirement colonies, of course, but single family homes out side city limits. Most counties have restrictions on living in an RV on the property, but not storing one there. I'm looking out the window at our coach now (and we aren't far from Lake Weir).
However, if you want suburban-style living ala' The Villages, something like Lake Weir is probably your best bet. Is that specific area important to you? Cause there are many RV-friendly communities in Florida, e.g. The Great Outdoors in Titusville.
