Ok jeep owners!! I'd like some help about towing. I have the hitch attached from the factory or by the previous owner of my 2004 Liberty. It's the 4x4 trail rated model with the 3.7 auto transmission. It seems that it's only rated class one according to the manual, but that doesn't seem right. Any of you know for sure? Class two sounds better, but the manual indicates you need the five speed. I don't want to ruin the transmission towing stuff too heavy for it. Thanks to those who respond.
