I am looking to tow a boat with my 2004 Grand Caravan. It is a SXT with a 3.8 L V6. I know that I need to put a few things, such as a trans-cooler, load-leveling suspension and I'm pretty sure there is a couple other things that need to go on it. I can't seem to find anywhere that offers a kit or even a list of what is needed and where to get it. Any advise on this would be much appreciated.
