I have always thought that the best way to determine whether a WDH is needed or not is to measure rear end sag on the TV when the trailer is attached. If the rear of the TV drops 3/4" or more (which in turn lightens the front of the TV) then a WDH is needed to redistribute the weight and keep the TV level. I need one with my Tacoma. If I had a heavier duty full size truck I don't really think a WDH would be needed. Is my thinking incorrect?
