Rineholio - Sorry to hear about your problems but I dont understand how your axle weights are different. Are each of your axles mounted independently to the frame?
The leaf springs on mine are connected in the middle with a pivot. I havent weighed each axle independently but I think with this setup the axles should be weighted the same even if the trailer is tilted some.
Our Boy Scout trailer had the torsion type axles mounted independently to the frame and also had 4 wheel brakes. It was very critical on it to have the trailer level. You really noticed a problem if it wasnt when you used the brakes. If you had the brakes set to where they would help stop ya and the trailer wasnt level the light axle would lock up very easy. I wouldnt own another trailer with tandem torsion axles again.
