The angle of the hitch ball is used to fine-tune the weight distribution.
Step one in adjusting the hitch is to get the spring bars tight enough to remove 40% to 50% of gross tongue weight off the rear axle.
Step two is to adjust the angle of the ball so that about the same percent of tongue weight goes to the front axle and trailer axles
Ideal setup will result in 20% to 25% of the tongue weight going back to the trailer axles, and another 20% to 25% of the tongue weight going to the front axle of the tow vehicle, and 50% to 60% of the tongue weight remaining on the rear axle.
So with 1,000 pounds tongue weight, adjust the spring bars so you have 500 to 600 pounds of tongue weight on the rear axle. Yes, this may take a couple of trips across the scales. After you have the spring bars right, then mark them or otherwise know exactly how to get the same tension when you hook up later.
When the spring bars have the right tension, then note the weight on the trailer axles and front axle. With 1000 pounds total tongue weight, if the weight distributed to the trailer and front axles is not 200 to 250 pounds each, then work on the angle of the hitch ball. On mine, the spring bars are fine, but I still have too much weight going to the front axle and not enough going to the trailer axles, so I've still got some adjusting to do.
