ANSWER: That is just the batch # that you gave me. The model # is only on the newer carriers. If you do not have the towing feature then you must have a double motorcycle carrier. Our VH-55 and the VH-SPORT motorcycle carriers both have the towing features. The double motorcycle carrier extends too far out to tow and haul 2 bikes at the same time. You can only haul 1 bike and tow.
