Since your tag, like mine, is rated for 10,000 pounds, I would think you would want to try to keep it as close but under 10,000 pounds with the trailer hooked up. That will put the most weight on the tag that Rockwell specified. Since I haven't had an issue with my tag brakes, I haven't examined the air brake circuit in the rear to see if there is a proportioning valve to the tag air brakes or not. Obviously we do have a gauge and valve to control the air bag pressure on the tag axle on both of ours which was not used after about 1993 or 1994.
