I have been toying with the idea of putting the tow bar on the 5 to pull my atv and jetski...at different times of course. I have read that the 5 is not supposed to pull anything really, but it can pull up to like 1200 lbs. I was wondering if I should invest in a universal transmission cooler? I have an '07 Touring still under warranty. The wife has a Tribute, and we have put the tow bar on that too, but it would be nice to be able to hook either up to the toys.
