Level the TT with the ball height. Level the truck (front axle load restoration) with the ball angle and number of links, or angle of WD bars.
Ford recommends returning the front axle load to half the amount that was lost. If the front rose 1" when dropping the tongue on the ball, you should adjust the WDH such that you have 1/2" rise. The rear will be whatever it is. 2" sounds right with a half inch rise in the front. If you return more weight to the front, the back will rise a bit more.
When in doubt, a trip to the scales might help. 3 passes, truck alone, truck with trailer w/o WD, truck with trailer w/ WD.
