Question:
Looking at part #76023, I am seeing mixed information on weather it does or does not fit the AT4. It says AT4 and then just after it says excluding AT4. It is very misleading. I am guessing it fits both but would like to know before I purchase. Thank You!

According to Draw-Tite, the # 76023 Class III hitch is indeed a fit for the 2021 GMC Acadia AT4.
If you'll be using the hitch for towing purposes, you'll also need a few other items to complete your towing system. For a trailer connector, use part # 118720 along with the # C45010 ball mount with pin and clip # PC3 and either the # 19260 1-7/8 inch trailer ball or # 63845 for a 2 inch ball.
I've linked to installation videos for the hitch and the trailer wiring harness.
