I inspected the 20 that KS shipped by rail. It arrived in California with no wheel chocks and the hand brake down! Every time the train started or stopped, the trailer ran to the end of the box-car and hit the end wall over and over. One wing came off its dolly and wore a hole into the wing spar (cap). If you ship by container, make sure the trailer wheels are chocked and nailed to the floor + set the wheel brake and duct-tape it in the full on position.
