THE STOW-A-BALL gooseneck hitch from Valley Industries uses a custom mounting bracket attached under the pickup bed to allow full use of the bed when not towing. The tow ball is stored upside down inside the ball socket, flush with the bed of the truck, until it's needed. When installed for towing, the tow ball rotates within the socket to eliminate coupler binding. The hitch is rated at 25,000 lbs. maximum gross trailer weight and 6,250 lbs. tongue weight.
