Ok, If I back off one link it will take me back to about 3450
What you are doing is extremely hard on your hitch and weight distribution bars. Start with this: weigh the trailer by itself fully loaded for camping; then weigh the tongue and load or reload the trailer to have between 10 and 15 percent of the trailer's weight on the tongue. 12-13 percent is ideal. Then, start the weight distribution process with the hitch and the tow vehicle. It should go much better if your trailer's weights are known and the tongue weight is within 10-15 percent. It should not be a fight to get the hitch dialed in properly. Then find out what Ford recommends for returning the tongue weight back to the front axle and use that number. All should be well then.
