The Roadmaster Direct-Connect Baseplate for 2019 GMC Sierra 1500 Pick-Up/Limited models is a crossbar-free connection to your motorhome-mounted tow bar. It mounts directly to the vehicle frame, making installation time quicker compared to traditional systems. The removable arms attach securely and can be taken off quickly for a low-profile appearance when not in use. Built from high quality steel and a durable finish that withstands rust. Note: Roadmaster direct-connect baseplates will only work with Roadmaster tow bars that slide into a trailer hitch, such as the Blackhawk, Blackhawk 2, Falcon, or Falcon 2. These baseplates will not work with tow bars that require a hitch ball. Fitment • 2019 GMC Sierra 1500 Limited Pick-Up Fits 2wd & 4wd.• 2014-2018 GMC Sierra 1500 Pick-UpFits 2wd & 4wd.
