The function of a wdh is to take weight off the tongue, right? How would you even measure the tongue weight with the wdh in place?
Well, sort of. A wdh transfers load from the hitch ball itself onto the front axle of the tow vehicle and also the trailer axles. Without a bunch of crazy, indecipherable calculations, the only way to really know for sure is to weigh truck and trailer axles before and after wdh hookup. I don't know if the 650 lbs for the Taco is with or without wdh, but it does seem like although Toyota makes tough trucks, the US market ones have soft, squishy springs that probably just about bottom out with 650 pounds right on the hitch.
