An Extra Ten Inches Clearance Between Your Truck and RV.

Note: The top plate is 10" square with the holes for extra bolts inset 1/2". If it is not possible to bolt to the bottom of your king pin box, you may have to weld it.

Everyone who tows an RV needs more clearance between the truck and trailer.

You can always use more room for maneuvering, especially if you're towing with a short bed truck. An extra ten inches between the rear bumper and the bulkhead of the trailer makes things easier, too. The RV5 adds 10" of new clearance from king pin center to king pin center, giving you the extra clearance you need in a strong, easy to install accessory.

NOTICE: The RV5 should NOT BE USED in conjunction with the RV1, RV2, RV3, RV4 or any other brand fifth wheel gooseneck adapter. NOT RECOMMENDED for king pins over 18" in length, (may cause the back of the pin box to hit the bed rails when turning)
