I tow 1000 around town regurlaly with mine and did without my other vans. If you are carefull you can get away with it. Trans cooler is a must, anything over 1000 lbs probably need brakes. I towed my Dodge Shadow on a U-haul dolly behind my '93 for a 300km trip. I wouldnt recomend it but I was carefull and didnt damage anything.
