Well, that may work out well for you in the end? Now, you should better understand about the coach's frame rail extensions and the fact Ford had nothing to do with manufacturing, designing, or testing them. If that hitch had fit, it would have been pure coincidence!
I've seen some where the lightweight steel tubing used within the floor of the coach actually provided most of the hitch's capacity to carry tongue weight!
