Hey Terry, the Blue Ox Avail BX7421 our part number # BLU28QV is the current version of the Avail whereas the 7420 was the initial version. Only real difference is the finish. The 7421 has a newer finish that's a bit more durable but other than that the functionality is the exact same. Do you have the 7420?
