"Old school fifth wheel hitches put the load slightly ahead of the rear axle, but people seem to throw that idea out the window with the Anderson and don't care where the load is front to back.
The Anderson has no adjustment that moves weight rearward, or forward. The weight is centered on the trucks gooseneck ball. As long as you either have the factory prep setup for the ball or make sure and mount the after market ball or rails correctly the weight distribution is the same as an old school fifth wheel hitch.
