Thanks. I see it lists the refrigerant in the last printing for my 2013. The 27oz is for all 2.0, so not related to tow package. But I do have the factory tow package and I went outside and looked and I do have an auxiliary air cooler. Whether this comes with all 2.0's or just the ones with tow package I cannot answer.The link I provided about seven posts up contains links to all four of the 2013 printings.
I have one of the earlier 2013 paper versions and the fourth one, and the fourth is much thicker than the first.
