  • Trimming of spoiler, air dam, bumper, grill or plastic fascia may be required on some models of this vehicle.
  • This is a direct-connect baseplate, to which any motorhome-mounted Roadmaster tow bar will attach. It neither uses nor will it accommodate Roadmaster's crossbar. As a result, there are no mounting points for Stowmaster tow bars, Guardians or Tow Defender part 4700. Tow Defender part 4750 will fit. In most cases, Roadmaster makes a crossbar version of this baseplate that will accommodate these products. Refer back to the fit guide to identify a crossbar version.
