Blue Ox motorhome mounted tow bar but you'd like to adapt it to a Roadmaster baseplate. This kit features new connectors which are specifically designed to adapt your tow bar to our baseplates. Simply replace the Blue Ox ends with those in this kit for an easy connection. If your baseplate is a direct-connect, your tow bar will pin directly to the baseplate arms. If it's a crossbar-style, then your tow bar will pin directly to the quick-disconnect crossbar.
