Take a look at the Andersen WD hitch. Yes I said WD but if you look at this hitch you can use or not use the WD aspects of the hitch, depending on how much tension you place on the chains, and it only weighs 60lbs. It will offer excellent sway control.
Not familiar with your receiver but this approach will be much better than just dropping the trailer on the ball.
