Thanks, for the SERIOUS answer Jay(thumbs nose at other Cretins, jury still out on Bob). It's a dual axle trailer and the centre of gravity will probably be slightly in front of the 1st axle(nearest truck). Shifting shouldn't be a problem...we're talking about 20 or so bags of cement, 3-4 yards of sand in it's own separate container(attached to the trailer), and some relatively light machinery...fully loaded about 10,000lbs.

Half of communication is listening. You can't listen with your mouth.
