A fifth wheel to gooseneck king pin box is a specialized hitch component that allows you to tow a fifth-wheel trailer using a gooseneck hitch in your truck bed. This setup is useful for people who own a truck equipped with a gooseneck hitch but need to tow a fifth-wheel trailer, which typically requires a fifth-wheel hitch.

Key Features:

  1. Conversion Capability: The king pin box replaces the standard fifth-wheel pin box on your trailer, converting the fifth-wheel kingpin into a gooseneck ball mount. This allows you to connect your fifth-wheel trailer directly to the gooseneck hitch in your truck.
  2. Adjustability: Many fifth-wheel to gooseneck king pin boxes are adjustable, allowing you to fine-tune the height and angle for a better fit between the trailer and the truck.
  3. Improved Maneuverability: Some designs incorporate shock absorption and pivoting features to reduce stress on the trailer frame and improve ride quality, providing a smoother towing experience.
  4. Compatibility: These conversion boxes are designed to be compatible with various truck and trailer configurations, but it's essential to ensure that the model you choose fits both your truck's gooseneck hitch and your fifth-wheel trailer.

This setup is popular among RV owners and people who need to switch between different types of trailers without having to change the hitch system in their truck.
