sorry...should have specified 2022...
i have the 2022 RST, 3.0 diesel, max tow package, 3.73 rear end and all this is cleared to haul 13000 lbs...
unfortunately, when hooked up to my new travel trailer, a Service Trailer Brake message is displayed
in the DIC...GM says the cause is unknown and they are working on it...so much for going south for the
winter....
