I'm looking to buy a 2009/2010 escape with the 6 cyl with or without factory tow package. With a class 2 hitch can I safely tow a small eyebrow trailer that would end up maybe 2000lbs? It seems with the 6cyl towing capacity is 3500lbs. I know it would be best with the factory tow package but what about without. What does the factory tow package come with? I know the tow package includes a larger fuse block but what else? Transmission cooling looks to be standard?
