Zoning that restricts RV use on your own land

Many communities and/or housing developments have specific regulations regarding the 'use'/'storage' of RVs on private property. When we lived in NJ, our town allowed one to keep his RV on his homesite, but it had to be placed in accordance with all zoning rules regarding 'set backs'. In our community here in the Myrtle Beach area, we are allowed to keep our MH with us but it must be on a concrete slab. As for allowing someone to stay in it, NO - but we have used it a few times for 'overflow' family after explaining to our neighbors that it was temporary/only while they were visiting. No one cared, so no one reported it! Did the same when we lived up in NJ. My inlaws loved their 'apartment'!! Agree with those who say 'using' an RV is far different from 'storing' it. Hopefully local regulations also know the difference.
