I just Googled some HP/towing info:
# 2.5-liter, five-cylinder Broad Torque engine
* Peak horsepower, 109 @ 4,500 RPM
* Peak ft./lbs. torque, 140 @ 2,200 RPM
* Towing capacity, maximum 4,400 lb. braked-trailer
# 2.8-liter, 6-cylinder VR6 engine
* Peak horsepower: 140 @ 4,500 RPM
* Peak Ft/lb. torque: 177 @ 3,200 RPM
* Towing capacity: max. 4,400 lb. braked trailer
* 4-wheel disk anti-lock braking system
I like the idea of a Eurovan as a tow vehicle, but 4400 pounds pulled with 109HP/140FT-LB seems a bit wishful to me

Maybe John will check in with some real-life observations .....
