Not sure if this is the right place to ask, but here goes. I have a Chrysler Town & Country van with a 3.3L engine. According to the specs it has a towing capacity of 3,700. This surprises me as the van doesn't seem to be a power wagon. My boat and trailer is right about 3,400 pounds. If I take everything off the boat and keep the tank close to empty, do you realistically think the the van can handle about 3,500 pounds? Will I begin to wear parts (engine & trans) if I tow close to its limits? Thanks guys.
