Due o the way non-tow Enclaves are assembled, it has thus far been expensive and a big headache to retro fit the Enclave for towing, with most of the issues being with the electrical system. There's been a lot of discussion about this over on the Acadia forum if you want to read more...
My suggestion would be that if you ever want to do any towing--even occationally-- with the Enclave, to go ahead and get the tow package. It doesn't cost that much now, but will be much more expensive down the road.
