In my opinion only, the Andersen Ultimate imposes little to no additional stresses on the 5th wheel frame and kingpin assembly than the standard 5th wheel hitch.
Unfortunately physics doesn't agree with your opinion. There is no doubt it increases the forces on the trailer frame. To give you and idea of what it is doing, take a broom stick:
- Hold it in the middle and have someone pull from just below your hand.
- Then have them pull from the bottom.
Which one is easier to hold your hand steady without any twisting?
It all comes down to if the manufacturer accounted for these forces in the design.
He was not referring to goose neck extensions. The Ulimate pulls on the King pin at the same horizontal plain as a conventional hitch. If the Anderson adapter is installed behind the kingpin then pin box is shortened slightly, and if in front of the kingpin it is extented slightly.
