Hi, welcome to the forum.
Don't know what you have in mind for towing. There are a wide range of hitches/towing ratings. I think a Traverse is suitable for Class I, II or III depending on engine, drivetrain, etc. Provide more details about your vehicle and the item you want to tow and somebody here can probably provide more details.
As a side note, I'm aware of an RV dealer in London, Ontario (just outside Detroit) that installs a wide variety of hitch packages. Andy Thompson, the owner of Can-Am RV, is an expert in the field. He's willing to speak to people even if they aren't customers. Give him a call.
