Jerry, what I do is to go to a scale that will weigh each of the three axles at the same time, then adjust the Tag to get the right amount of weight on the front axle. I'm fortunate to have a State DOT scale just a couple of miles away from the house, that is almost never busy. They let me get positioned with one axle on each of the three scales, thenI go to the rear and adjust the air pressure until the weighmaster tells me it looks good. Obviosly, getting a setup with a seperate scale for each wheel or set of wheels would be ideal. Then you can not only get the three axles adjusted, but could move stuff around to try to balance the corners as well.
