Another question, since I know this is the place to go. Any opinions or experiences on towing with a Ford Windstar, 3.8l v6 w/transmission cooler. Boat is a 21 ft. sea ray and trailer, approx. total weight, I'm guessing is around 4800lbs. I will be towing it about 15-20 miles, and am not quite sure it can handle it. Thanks.
