The ball mount will be determined by some measurements you will need to take. I will add a link to a page showing how to calculate the rise or drop necessary for your set up. You want the trailer to be level with the vehicle when towing. Make sure you take the hitch height and trailer coupler height measurements on a level surface.

Once you know the drop or rise, select a ball mount with at least a 7,000 pound rating. It will probably use a 1-1/4 inch shank diameter ball, which is heavy enough to handle your almost 7,000 pound set up.

Your trailer coupler will determine ball diameter, it should be stamped somewhere on the coupler or the trailer labels.

If you write back with your trailer coupler height and hitch height, I will be able to give you part numbers for exactly what you will need.
