Eyeballing it from 50 feet is not the most precise method. Measure from the trailer frame to the ground to achieve level or slightly nose down attitude of the trailer. Weight distribution bars should be parallel with the trailer tongue. Measuring the height of the tow vehicle front wheel well before trailer attachment, after trailer attachment and after tensioning the weight distribution bars will get the weight distribution adjustment close. Ford says lower the fender at least half of the initial rise. However, the only way to know for sure is to make the three passes across the scales. I ended up with 72% of the weight returned to the front so it's only 100 lbs. lighter than without the trailer attached.
