Do you mean a weight distribution hitch? Yes, I use the Equalizer 4 way anti sway weight distribution hitch set up. It helps quite a bit especially in windy conditions or when a semi passes by. The purpose of a WDH is to transfer some of the weight to the front of the tow vehicle so the rear axel is not carrying the whole load. I have towed without a WDH and will never do that again. It was "white knuckles" the entire trip. Well worth the money. To me it is absolutely essential.
