The numbers I get are 9150 lbs with 3.73 gears and 11,150 lbs. with 4.10 gears. This is assuming 17" wheels, a weight distributing hitch and trailer brakes.
With a 2500, the man probably won't pull you over and check weight like I've seen them do on 1500 trucks. BUT, keep in mind, even though the truck will handle it, if you are over capacity and have an accident, your insurance company is well within their rights to deny any and all claims. Property damage could be enough to break you and God forbid if there would be personal injury or worse, you could lose everything, including your home.
