Most definitions of RVs say they aren't intended for permanent residency. Even Wikipedia says "RVs are not designed to standards which permit safe full-time living. Many states Department of Insurance do not recommend or authorize the use of RV's/Motorhomes as permanent dwellings."
My understanding is that there is a limit to the length a person can stay in any one RV park, at least in some states. My experience was with California, where the limit was six months, at least in the parks I contacted.
I see some parks linked to this site offer leases and annual maintenance fees. So it is possible to stay all year round, in one park, on the same lot?
Thanks for your help!
