Until I bought a tt I would have agreed. I have towed 14k before even knowing what a WDH was... I have towed lots of trailers and never worried figured I have a 350 no problem. Even when I was lookig for a 14k deck over trailer. I was looking to upgrade my hitch and the company said dont worry its a one ton. Then bought a tt and found out my hitch is only rated for 500 pound tongue weight load carrying. Plus, the rear of truck sags and front of tt is too low wihout wdh. I personally hate when trucks rear end sag below level! Also between my loaded truck weight and my tongue weight, im at 9, 620 pounds my gvwr is 9900
