I am presently towing my 1995 Maxum SC200 with my 1996 Nissan Pathfinder. It is rated to tow 5000lbs and I figure that my boat with trailer, fuel and gear is 4000lbs. I was wondering if anyone knows what the 5000lbs capacity is based on and if there are any simple upgrades I can do to my vehicle to help improve towing my boat. It pulls it, however, I would like to make it easier on my Pathfinder. One of the things I am presently going to do is install a seperate tranny cooler that is rated up to 18000lbs ( I realize this is only if the vehicle has the power to do it)to help the tranny. Any other ideas would be great. Anyone else towing with a 3.3L Pathfinder <br />Thanks
