We have a pretty stout truck and do not need WD as well, but for the life of me I would not get on any interstate and travel posted speeds with the kind of wind we get in our neck of the woods. Our WD hitch helps a bit with restoring weight to the front of our truck, more importantly for us it has integrated sway control that keeps sway down to a minimum, which is the primary we spend the 2-3 minutes it takes to install/remove bars. Can't tell you how many times we've seen HD trucks on the interstate that are going well below speed limit due to excessive swaying of the trailer they are pulling.
