Hi Smosher,
Welcome to the site.
I am not familiar with that equipment package for the TB.
I would check with the dealer to verify what is included with the V92. It is possible that the vehicle is equipped with heavier duty equpment( trans cooler, drive axle ratio,etc) but may not actually include the trailer hitch and wiring.
You can also go to the Chevrolet website and somewhere under customer care/support and chat with a representative and see if they can verify. Sometimes dealers don’t always prep the vehicle properly. It may have been missed. I noticed on mine after getting the license plates I have the incorrect front license plate that was in the car(not installed). My dealer is aware and they told me when my floor mats arrive they will have one if I don’t stop in before that. As much as we hope they would check everything, they don’t.
What color did you opt for.
