I am wanting to get a B&W hitch but I need the 5th wheel also. I want a heavier duty hitch than 18k. I read somewhere, cannot find it, that someone was using B&Ws flat bed companion that is rated for 22k in a pickup bed. Anyone heard of this or done it. As the 22k is fixed at like 10" I would be worried about not enough bed clearance. Any thoughts would be greatly appreciated.
