I recommend the Demco Channel Tongue Trailer Coupler # DM13689-52. I have included (below) a picture of the bolt measurements for you to compare for your trailer. It is made of sturdy steel with a silver powder coat finish, making it ideal for marine applications. eZ-Latch ensures fast, easy, secure hookup and disconnect. It is rated for 10,000lbs of trailer weight and uses a 2" ball.

Be sure to pick up Coupler Lock # e98887 so that you can lock the trailer up and protect it when attached or away from your vehicle.
