I've towed with a few different mini-vans in my past. As stated by many others, the combo with average loaded TV is often at max (and sometimes over) its max towing weight. And, towing large shape items is like dragging a parachute behind the TV as well (which creates even more stress). Even with tranny cooler, one of our mini-vans blew its tranny - from "stress" overload. Today, I no longer tow mini-vans at their max towing ability. IMO, mini-vans are good to tow up to 2,000 lbs and only a few times a year (like local dump runs). Anything more and its stressing the mini-van too much. As implied, "been there, done that and paid dearly for the t-shirt / to rebuild its tranny".
