I would double check, in this guide it suggests trailer brakes are required over 1000lbs http://www.gmc.com/content/dam/GMC/global/master/nscwebsite/en/home/Vehicles/Shared_resource/pdf/2012-gmc-trailering-guide.pdf
It also weighs quite a bit for being pushed with a 3L engine.
My not try a 2012 Escape, they are clearing them out now as the new model just came out. 3.0L 4x4 is good on gas (8L/100 on the highway)but I wouldn't want to tow much over 2000lbs with it even though its rated for 3500. Depends what you want to tow now and how much down the road.
