If you're a member of the Elks Lodge there are several Elks Lodges in Florida that have very nice RV accomodation with full hook ups for just a few bucks a night.....$12 to $20 a night, depending on location. Some are actually just a donation. We stayed three months. For longer term, we stayed three months at Olde Mill Stream RV Resort in Umatilla, Florida. Great location to Ocala National Forest (about a mile down the road) and about an hour west of Daytona Beach. Walmart and all the services of any major area within 10-15 miles yet off the beaten path and away from interstate freeways.

There's several RV parks around Sebring, Florida that are very reasonable if the budget is a concern but the scenery down there isn't to exciting.
