This custom underbed installation kit leaves your truck bed wide open when you’re not towing. The hitch uses a single 4" diameter hole for the gooseneck ball and mounts underneath the bed, giving you a flush, factory-clean surface once the hitch is removed. You can even flip the 2-5/16" ball upside down into the receiver to stow it out of the way, so you get full use of your truck bed for hauling gear or loading pallets.
Instead of installing separate systems, this setup works as both an underbed gooseneck hitch and the foundation for a B&W Companion fifth wheel hitch. When you’re towing a gooseneck trailer, it provides a solid, 30,000-lb gross towing weight and 7,500-lb vertical load limit. When it’s time to tow a fifth wheel, just drop in your Companion hitch (BWRVK3500 or BWRVK3400) into the square opening and lock it with the handle. It’s a quick way to switch between towing styles without adding extra rails or drilling new holes.
You won’t have to weld or drill into the frame to mount this kit. The custom brackets bolt directly to existing holes in the truck’s frame for a secure fit. The only drilling required is for the safety chain loops and the 4" center opening in the bed. The operating handle is set up to be reached from the rear driver’s-side wheel well, and its built-in steel pin locks the gooseneck ball or fifth wheel post in place. The heavy-duty powder-coated steel construction resists corrosion and stands up to years of heavy towing use.
