Explantion: Proper weight distribution helps to ensure the stability of both the towing vehicle and the trailer. In the trailer, the bulk of the load should be over the axles. If a heavy load is positioned at the front of the trailer, this will result in too much nose weight on the hitch of the towing vehicle and make it difficult to steer. If a heavy load is positioned at the rear of the trailer, this will result in reduced weight on the rear axle of the towing vehicle, which will make it more unstable.
