Just one additional comment on this point. WDH will get rid of most of the squat, but not all. More important it doesn't have to get rid of all the squat. If your back end squats less than 2" after the WDH is setup that's nothing to be concerned about, so long as the weight is put back on the front end to restore steering control.
My Sierra squats about 2.5" without the WDH. It's about 1.5" down with. The entire rig is actually very level and tows beautifully.
