make sure you use the lighter of the 2 vehicles to begin the tiltover and the heavier one to control the drop. It won't take much to start it to tilt over but once it reaches about 30deg off vertical, you will have the weight of the bin + gravity. You will also find that once you exceed about 70 deg from vertical, (almost horizontal) you will not have much control at all due solely to the angle of the ropes or winch line leading back to the braking vehicle. If possible, lay it down directly onto the trailer.
