Andersen Hitches Ultimate 5th Wheel Connection — Gooseneck Mount (Toolbox version) (3220TBX)

Lightweight 5th-wheel connection

Andersen’s Ultimate 5th Wheel Connection is a lightweight aluminum (or steel rail) 5th-wheel style hitch that couples with a gooseneck ball. This SKU (3220TBX) is the Gooseneck Mount (Toolbox version) configuration on andersenhitches.com.

Toolbox versions use a base offset so the hitch clears an in-bed toolbox (per Andersen).

Andersen emphasizes a greaseless ball connection, full bed access when removed, and SAE certification on complete gooseneck mounts.

Who it's for

Diesel and gas HD / light-duty trucks set up for gooseneck or rail-mount 5th-wheel towing that need Andersen’s Ultimate Connection in this mount style.

Fitment notes

• Short-bed trucks: Andersen lists short-bed compatibility without a slider for this family; verify your bed length and kingpin.
• Truck-bed rails are sold separately when the listing is rail-mount.
• Made for truck towing applications; not a gas-car specialty part. Always match GTWR and tongue ratings to the tow vehicle and trailer.
