The Andersen and Pullrite Superlite are not really gooseneck hitches. They do use a ball, but the ball is on top of an elevated frame and the ball receiver is mounted right on the pin box frame. True gooseneck hitches have the ball in the bed and an extended arm from the pin box to reach down to the bed, hence the “gooseneck” looking frame member. The gooseneck adapters are essentially a lever putting additional torque stresses on the pin box. The Andersen and Pullrite do not put that same torque on the pin box.
Now after being a bit long winded, there have been some reports of the Andersen failing. But many are very happy with them.
