"Trailer", "house trailer", "camping trailer", "mobile home", "trailer coach" and "concession trailer", mean any vehicle or structure constructed in such a manner as to permit occupancy thereof as sleeping quarters, or the conduct of any business, trade or occupation, or use as a selling or advertising device, and so designed that it may be mounted on wheels and used as a conveyance on highways and streets, propelled or drawn by its own or other motor power. The character of its foundation or means of support or the permanent nature in which a trailer is affixed to or incorporated with other structures or to the land shall not serve to change its classification as a trailer.
