Odds are some adjustment will be wise, even if not absolutely necessary. Hitch height is one variant, and the amount of weight distribution needed is another. It may be that you will simply use more or less tension on the spring bars when you hook up, but it could also mean changes to the ball mount height or angle. Any good hitch shop could do it, though too often they just set it by guesswork rather than the procedure defined for the WD hitch.
You can easily do it yourself, or get a friend or local shop to assist. The instructions for the Centerline WD hitch are simple and include pictures and detailed explanations. Anybody with basic hand tools and a modicum of mechanical skill can do it, so there should be no need to drive two hours to a shop that may or may not have any better hitch skills than the guy next door. Download this manual and follow the instructions to measure and adjust.
