The B&W Hitches TEXA4200 Extend-A-Goose is an engineered adapter that lets you tow a standard fifth wheel trailer using your existing gooseneck hitch ball -- without installing a dedicated bed-mounted fifth wheel hitch. If you switch between a flatbed gooseneck trailer and a fifth wheel RV, this adapter gives you that flexibility without permanently modifying your truck bed or swapping hitches every season.
Many truck owners run a gooseneck hitch for work -- flatbed equipment trailers, livestock haulers, or utility trailers -- but want to use the same truck to tow a fifth wheel RV. Swapping to a full bed-mounted fifth wheel king pin hitch is expensive, time-consuming, and takes up permanent bed real estate. The Extend-A-Goose solves that problem cleanly.
The TEXA4200 drops into your existing gooseneck hitch ball (standard 2-5/16 inch gooseneck ball) and converts it to accept a standard fifth wheel king pin. The adapter extends rearward to properly position the fifth wheel coupling over the rear axle for correct weight distribution and turning clearance.
Mounts directly to a standard 2-5/16 inch gooseneck hitch ball already installed in your truck bed -- no additional drilling or welding required.
Upper coupler accepts a standard 2-inch fifth wheel king pin, compatible with the vast majority of fifth wheel RV trailers sold in North America.
At 31.5 inches in length, the adapter positions the king pin coupling correctly over the rear axle to maintain proper towing geometry and cab clearance.
Welded steel frame weighing 60 lbs is built to B&W's commercial-grade standards -- the same manufacturer behind the Turnoverball and Companion fifth wheel hitches.
The TEXA4200 is the right solution if you already have a B&W Turnoverball or comparable under-bed gooseneck hitch installed and want to occasionally tow a fifth wheel without committing your truck bed to a full fifth wheel hitch. Common use cases include:
The Extend-A-Goose requires no permanent truck modifications beyond having a gooseneck hitch ball already installed. Installation is a bolt-on process:
At 60 lbs, the adapter is heavy enough to require care when lifting it in and out of the truck bed. Two-person installation is recommended for safe handling.
