Welcome back Shelly! The B&W Tow & Stow 2-Ball Mount item # BWTS20066BMP is the correct one for the GM MultiPro Tailgate. It's got the angled top and extra drop that allows it to be left installed on a 2-1/2" hitch receiver without destroying the tail gate.

The Tow & Stow 2-Ball Mount item # BWTS20066BMP fits a 2-1/2" hitch receiver and offers a 7" drop. It comes with a 2-5/16" hitch ball with a 18,000 lbs towing capacity and a 2" hitch ball with a 7,500 lbs towing capacity.

We also have the Tow & Stow 3-Ball Mount item # BWTS20067BMP that also works with the GM MultiPro Tailgate. This one also includes a 1-7/8" hitch ball.

I recommend using the etrailer Hitch Receiver Lock item # e98881 to secure the Tow & Stow 2-Ball Mount item # BWTS20066BMP to your Sierra's hitch. You'll also want to pick up the Pin Surround Lock for B&W Tow & Stow Hitches item # BW82AR to secure the ball platform itself. These locks will keep your ball mount from walking away while your truck is parked.

Excellent product , sturdy … easy to use . Looks good and it works perfectly with my GMC HD and the flex tailgate. You won’t regret the purchase… guaranteed

@JayO Thanks for sharing that feedback Jay. Happy to hear the B&W item # BWTS20066BMP is working so well for you.

Works great with Multi gate in dropped position. If you flip it up for high tongue trailers it hits tailgate when folded out.

@Christopher Great tip Christopher. Yeah the rise position on the item # BWTS20066BMP definitely doesn't work with the Multi-Pro tailgate. That's typically not an issue on the taller trucks with a 2-1/2" receiver but thanks for point it out.

@JerredH Only reason I know this is I have to use mine in the "rise position". My trailer has the off road wheels and tongue sits high. As an added tip I recommend pushing and holding the upper button until you hear a beep. That way you can't accidentally drop the multi function.
