Hey all, great forum! We just bought an '07 Latitude last saturday and love our little Jeep. It didn't come with the towing package so I am looking to install it myself. I know the hitch and harness aren't too difficult, but what about the HD cooling? I will be towing a 10 foot tent trailer that weighs 1600lbs. To give a generous figure I'm going to say 2500lbs loaded. So my questions are A) is the heavy duty engine cooling hard to install? B) Do I even need it? and C) do I need a transmissin cooler as well? thanks!
