If you own a 5th wheel trailer but prefer the simplicity and space-saving design of a gooseneck hitch, a 5th wheel king pin box adapter is a smart upgrade. This unique device allows you to tow your 5th wheel trailer using a gooseneck ball hitch in your truck bed—eliminating the need for a bulky 5th wheel hitch.

What Is a 5th Wheel King Pin Box for Gooseneck Hitch?

A 5th wheel king pin box for gooseneck hitch is an adapter that replaces or attaches to your trailer’s existing king pin box. Instead of connecting to a traditional 5th wheel hitch, it converts the connection to a gooseneck coupler that latches directly onto a gooseneck ball hitch in your truck bed.

Key Benefits

  • Increased Bed Space: Unlike a 5th wheel hitch that takes up significant room, a gooseneck ball sits nearly flush with the truck bed, leaving more space when you're not towing.
  • Simplified Setup: Gooseneck hitches are easier to install and remove, making your towing system more flexible and user-friendly.
  • Cost-Effective: Avoid the extra expense of purchasing and installing a dedicated 5th wheel hitch.
  • Strong and Secure: Many adapters are cushioned and reinforced to handle heavy loads while reducing road shock and stress on your trailer.

Popular Options

Products like the Reese Goose Box and Gen-Y Executive Gooseneck Pin Box are designed for heavy-duty use and offer built-in shock absorption for a smoother ride.

Whether you're a weekend traveler or a full-time RVer, upgrading to a 5th wheel king pin box for gooseneck hitch towing offers convenience, durability, and versatility.
