I have same model and pull a car trailer a lot. You just need to wire in an electric brake controller if your chassis does not have one already. Chassis has a hitch on the back, std 2 inch square receiver. You need a drop hitch that will put your trailer level on flat ground. You will not need a weight distributing hitch for a std car trailer.
Trailers have electric brakes, that is actuated by the controller inside the cab. It sends a proportional signal to the brakes dependent on how much braking force is needed. Just look up trailer brakes and a diagram and it will make more sense.
Here is a video that describes it pretty good, plus there are many others on youtube.
Beyond that just make sure you also have trailer lights and plug if not already equipped, should be there.
