Level Or Not
I don't think anyone ever said that self-leveling would redistribute weight from the rear axle to the front axle. In truth, when the truck is level, the 5er runs a little nose high. Bleeding some air out to improve ride comfort helps lower the nose a little. Whatever weight is added to the front axle when hooked up is purely a function of the positioning of the 5er hitch, the truck frame and the suspension. The only way to know the weight of any wheel or axle is to go to the scale when loaded for a trip. Each wheel and each axle must be weighed. Prior to weighing with with the 5er connected, the truck must be weighed so that the kingpin weight can be calculated.
