Yes my XT6 Sport has the factory hitch receiver and 7 prong harness included in the smart towing package. It’s a 2020 and the owner’s manual states the tow limit is 4,000 lbs and the hitch weight limit is 400 lbs. It’s easy to find a small travel trailer under 4,000 lbs but not with hitch weight under 400 lbs. It seems to me that a weight distribution hitch would allow more hitch weight, but since I cannot get anyone affiliated with Cadillac to approve that, I won’t be exceeding the 400 limit on the trailer tongue weight. I will not be jeopardizing the vehicle by unapproved towing. Thank you for your response.
