All trailers have the CG in front of the axle, they track better this way, just like a caster on a shopping cart, the load is in front of the wheel. The problem comes from too much load in front and that takes weight off the tow vehicle steer tires making for hard steering and the possibility of trailer sway due to not enough load on the trailers own wheels, this is where the LD hitches come in to play. If the load is off it doesn't matter quite so much as the weight is redistibuted back onto each vehicles respective wheels, adding in the antisway system really cuts the chances of the trailer getting away.
