Thanks Ray.
Hi Kane123. We towed an Edge M-22 with a 2010 Buick Enclave for two years. The Buick has a slightly lower tow rating, for reasons I do not know. On the GM forums the suspicion was that the front grill gave a lower air flow to the rad. I installed a Trucool (sp?) transmission cooler and a Reese sway control hitch. I would highly recommend both. When set up correctly, the trailer had almost zero sway. You can expect around 10 mpg. 2010 was the first year for the direct injection engine. The tow package has a two/haul switch, which modifies the shift points.
As long as your trailer is within the tow rating of the Traverse, and you don't have aspirations of pulling the trailer over the Rockies, you should be fine.
