Learn how to adjust your hitch. There should be a manual online if you do not have one. Start from scratch. Trailer should be level when all hooked up. Tongue weight should be around 12%. Most hitch makers want you to do initial set up on very flat ground and measure front fender heights. You measure the truck without trailer and record that. Then measure the fender with the trailer fully resting on the ball but no weight bars attached. The goal then is to get the fender height to be halfway between those 2 measurement when the bars are attached.
After doing that, check to make sure the trailer is level by measuring the bottom of the frame to the parking lot at both ends. It should be within an inch to an inch and a half. A little nose low is better than nose high. Any more than an inch and a half and you must move the ball up or down to compensate. That may change the fender heights so you will need to check the fender measurements again.
Takes about an hour to do it right but once you do it will tow much better. Then you can get weighed and find out your true axle weights.
