B&W TS20066BMP Multipro Tow & Stow™ Dual Ball Receiver Hitch, Fits Any 2-1/2" Receiver

The MultiPro Tow & Stow has been designed specifically to work with GM's MultiPro tailgate. Just lock it in your receiver, stow the ball assembly underneath, and you're free to use the inner-gate and step feature of your MultiPro tailgate. Multiple ball sizes eliminate the need for multiple ball mounts. This trailer hitch stows under the vehicle when not in use.
