Drops into your pucks, gives you rails.
Step 2: ISR Gooseneck Adapter
Mounts to your rails, gives you a gooseneck ball.
Step 3: Gooseneck Pinbox
Replace your trailer's pinbox.
Note
Ball on rails has no clearance underneath, so Gooseneck Fifth Wheel adapters won't work. You'll need a gooseneck pinbox on your trailer.
