If it were me, I'd get a longer drop drawbar, the part that slides into the hitch that the head with the ball bolts onto. That way you could get the trailer to sit level. Then I measure the front and rear bumpers of the truck without the trailer. Then load the trailer and hook up the ball. See how much the back bumper goes down from its unloaded height. Then start experimenting with how many links of chain you need to use on the WD setup. The ideal # of links will get both the front and rear bumpers of the tow vehicle to lower the same, or within 1/4" of each other. So if the rear bumper drops 2" and the front drops 1", then you will need to go another link or so lower on the chain of the WD bars. I hope this was what you were asking, and that I didn't confuse you.
