Here's the deal, I have been considering a W.D. hitch for a while now but don't know if I really need to fork over 400.00 for one.. I'm towing right around 6,500 - 7K, w/ 450-500# of tounge weight with an F-150, I have coil overs and I purchased a heavier duty hitch rated for 1000 toung and 10K towing. I'm pretty sure this, itself does not increase the towing capability of the Ford unless I go to a W.D. It tows great in the current set up, zero swaying and very little if any bouncing with the torsion axle trailer. Question is, aside from making me legal, will the W.D. set-up do anything at all ?????
