Product Description
The Roadmaster 031-5 is a tow bar adapter kit for connecting newer Roadmaster Sterling, Nighthawk and BlackHawk All-Terrain tow bars to a Blue Ox base plate. It replaces the connection ends on the tow bar arms so they pin to Blue Ox base plate tabs, letting you use your Roadmaster tow bar on a vehicle with Blue Ox brackets.
The kit is sold as a set of two, one for each tow bar arm. Mounting hardware is not included per the manufacturer data. Older Sterling and BlackHawk All-Terrain tow bars (below the serial numbers listed) use the Roadmaster 031 adapter instead.
Compatibility
- Roadmaster Sterling tow bars with serial numbers above 14,500
- Roadmaster Nighthawk tow bars

Pro tipTow bar setup tips
- Rating first. The tow bar’s capacity must be higher than your towed vehicle’s loaded weight.
- Keep it close to level. Tow bar makers specify how far the motorhome hitch and the base plate connection can be apart in height — use a rise or drop receiver to bring them in range (see your tow bar’s instructions).
- Check base plate compatibility. Different brands connect differently; mixing brands requires the right adapter.
