Our condo community in FL doesn't officially allow RV's on the premises except to unload and load ONCE EACH per year. (Our Canadian owners usually travel down in their RV's, unload their clothes, park in an off-site lot, repack up and return North 182 days later.)
However, since our individual condo association controls our own parking lot, if you can get the association President or Board of Directors to let you use the lot to load/unload, you're OK for up to 24 hours at a time. (You can even use the 120 VAC outlets in the Golf Cart parking to cool down your refrigerator.)
Since DW is a full-time electric wheelchair user and we have a 3rd floor apartment, we have an automatic dispensation from our building Board to use the lot whenever the elevator goes out of service. (It doesn't hurt that we are both BOD members!)
But, our off-premise storage has all the amenities you'd want (potable water and air, dump site, vehicle wash location, and they'll run a 15A line to your spot when needed). Owner is an RVer and built this operation to give us what he would want in a storage facility.
