Be careful there are a lot of regulations regarding deeded campsites. Many of them have a limited number of days you can use the sight in a calendar year. While your RV can remain its your physical body that can't be there. Some of the ones in Washington state have 180 days in a calendar year limits, others are 270 days in a year. When you are there for an extended time you have to leave for at least one full day in every 30 days time. Their calendar year varies, some start the clock in June, others in January or some other month.
Sometimes if the land is on an Indian reservation you are purchasing a long term lease rather than actual ownership of the land.
If you don't abide by the rules of the community organization you can be kicked out with no access to your place. If you get behind on the fees they can take your property away.
Always have an attorney read through the contract and explain to you the sometimes ambiguous language before you purchase the lot. Also all the pitfalls that might end up with an unexpected forfeiture. Due diligence is required, contact your local attorney generals office and see if there are complaints against the group.
Anytime you want to purchase a piece of property part of the investigation should be to call local law enforcement and see if there are neighborhood reports on theft, car prowls, gang activity, ongoing domestic situations, registered sex offenders, etc. I learned that lesson the hard way, this is a true story. I bought a large house on 3/4 acre with a water view in a very high end, Island, community that was located on a private drive. At the start of the drive was a person who was on methadone, he had inherited the land. In the house on east side of me was a man who was only home on weekend release from prison, he was convicted on the Savings and Loan Scandal. The day after I moved in the man from the house on west side knocked on my door telling me he was required by the law to notify me that he was a paroled, convicted murderer. None of those men was a good neighbor in fact or attitude. There are advantages to renting and boondocking.
