Ever denied parking spot even though you legally fit?

I've never had that problem. However, just because your unit will fit into a parking spot does not mean you are allowed to park at that location.

If the ordinance or law states that there is no RV parking, it means RV's are not allowed to park at that location. Size has nothing to do with the parking situation.

The local municipality apparently does not want people parking and living it RV's at certain locations.
It doesn't matter if you park there for an hour or a week, your RV is not wanted at that location.
