Product Description

Revolutionizing the 5th wheel towing industry, Andersen Manufacturing’s popular Ultimate 5th Wheel Connection is now stronger than ever and features a patented ball-funnel to make hook up even easier! The Aluminum Ultimate 5th Wheel Connection 2 is the lightest, strongest, most innovative 5th wheel hitch in the world! Weighing in at a mere 35lbs, it completely eliminates the common struggle of getting your 5th wheel hitch into the bed of your truck. The base of this unit can be completely installed or removed in less than a minute.

Please Note: This unit is 4" lower than the standard Aluminum Ultimate 5th Wheel Connection Toolbox Version (part # 3220-TBX) and is mainly intended to be used with flatbed trucks that have a RECESSED gooseneck ball AND a large fuel tank or toolbox in the bed. If you have a large fuel tank or toolbox but your gooseneck ball is not recessed, please see part #3220-TBX. Using a 3221 or 3221-TBX base in a truck bed that has sidewalls may cause damage to the truck or hitch! Please call us if you have any questions. When you place your order please add a note providing us with a measurement with the distance from the top of the flatbed deck down to the top of the gooseneck ball. Also, because these have to be paired up with specific couple tubes, they take a few days to ship out.

The Ultimate 5th Wheel Connection gives you an incredibly smooth and quiet ride unrivaled in any other 5th wheel hitch on the market today. The ball of the Ultimate 5th Wheel Connection has nearly 3" of adjustable height and rides inside a greaseless coupler -that means no more dirty hands and no more mess! And since the coupler rides on a ball, it has more swivel in every direction of any 5th wheel hitch available. This also gives you the ability to couple or uncouple your trailer on uneven terrain. Now that’s convenience!
