My wife and I bought a 2023 all wheel drive Traverse without a towing package on it. We have been reading and the dealers are saying only a 1500 lbs towing hitch would work since we don’t have the tow package. To what I have read, the only thing we would really need is to upgrade the cooling system and we would be able to tow more. Would that work, or am I missing something and it wouldn’t work? Thank you!!!
