My F250SD has a very stiff suspension due to the shocks I put on it for hauling my truck camper. So when I tow my 17B (w/o camper, i.e. empty truck) I get quite a bit of bounce. Believe it or not the WDH helps with that. Especially since I-90 coming out of Seattle east to Ellensburg is beat to pieces. Might as well be driving on a back country road in Utah.
