WE go to Casa grande, Az in the winter the rent is about $500.00 per month plus electric in a very nice park with lots of amenities and activities.
In the summer we are in the Thousand Islands at a site that charges $1600 for the season. May 1, - Oct 1.
As we travel we boon dock, use National park campgrounds and stay on the Texas and Louisiana beaches free of charge.
Other options would be to workkamp or volunteer in a state or national park. IN return for your time they will usually give you a site with full hook up no charge. The TONTO national forest in Arizona has had an ongoing need for volunteers in the winter. Nice campground with other workkampers so you sort of have a little community.
We avoid RV club type things because that locks you in.
If you want PM me I would be glad to answer in detail or give you our Syracuse phone number and you can talk to us.
