Product Description
The Roadmaster 501 StowMaster is a Class IV, car-mounted tow bar rated for towed vehicles up to 6,000 lb. A car-mounted tow bar stays on the front of the towed vehicle when it's not in use, and it couples to a 2-inch hitch ball on the motorhome when you're ready to tow.
The StowMaster uses Roadmaster's Autowlok locking mechanism and self-supporting arms that adjust in both length and width, so one person can hook up without perfectly lining up the vehicles. A built-in safety strap is designed to keep the tow bar from separating if the primary lock fails. Safety cables are not included and are sold separately.

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.
