Ford fifth wheel prep package - how to tell if I have it?

If you get the B&W hitch, all you drill is one 3" diameter hole, for the ball socket, and four 3/8" holes, for the safety chain loops.

If you don't intend to use the ball to pull a gooseneck trailer and will only be using it with the Companion 5th wheel hitch unit, then you don't need to drill the 4 safety chain loop holes in the bed, just the 3" hole for the ball socket. The Companion mounts into the ball socket.
