Hi Tomasz! The correct adapter to use the Blue Ox # BX2527 depends on the serial number on your Roadmaster Sterling tow bar. If your serial number is 14,500 or below you need # RM-031. If it is 14,501 or higher you need the # RM-031-5 instead.

Do you have the rest of the parts picked out for your setup?
