I have a 2017 Enclave. Bought it new from the dealer. It came with the button on the console for a trailer. It also came with a hitch. My wife is digging up the window sticker and paperwork to see if it says, but basically wanted to know, How can I tell if it has the Trailering Package. Is the presence of a hitch and the button from the factory a good indictor? Or do they all come with that? I am going to be starting a mobile grooming business. I want to know if I will be able to pull a 2500-3000lb trailer without much difficulty.
