(1)(a) Before the department may issue a temporary subagency license to a recreational vehicle dealer engaged in offering new or new and used recreational vehicles for sale at a recreational vehicle show, a recreational vehicle dealer of new or new and used recreational vehicles shall submit to the department a manufacturer's written authorization for the sale and specifying the dates of the show, the location of the show, and the identity of the manufacturer's brand or model names of the new or used recreational vehicles.

(b) The department may issue a temporary subagency license if the location of the show is within fifty miles of the recreational vehicle dealer's established place of business or permanent location. The department may issue a temporary subagency license for a show outside fifty miles of the recreational vehicle dealer's established place of business or permanent location only if the product represented is new and is within the factory designated sales territory for each brand of new recreational vehicles to be offered for sale, and only those specific brands of new recreational vehicles may be offered for sale under the terms of the temporary subagency license.
