Pro tipBefore you order a base plate

  • Match year, make, model and trim. Base plates are vehicle-specific, and trims with adaptive cruise, front sensors or a different bumper often need a different plate.
  • Confirm your vehicle can be flat towed. Check the “recreational towing” section of the owner’s manual — not every car, transmission or drivetrain can be towed four-down.
  • Mixing brands needs an adapter. Base plate and tow bar brands use different connection styles (for example, a Blue Ox base plate with a Roadmaster tow bar). We’ll tell you exactly which adapter you need.

Product Description

Flat tow your vehicle behind your RV with confidence. This Roadmaster base plate is engineered specifically for your vehicle, giving your tow bar a strong, secure, vehicle-specific connection point with a clean, factory-like look when you're not towing.

This is one of our EZ4 Twistlock series brackets, which allows the visible front portion of the bracket to be easily removed from the front of the vehicle. The bracket consists of a main receiver brace, two rear braces, two removable front braces, and a hardware pack. The main receiver brace mounts to the frame rails and rear braces. The removable front braces install in the main receiver brace.
