The story says the truck backed in, they unloaded the hot tub, then after the weight of the tub was off the trailer, all the sudden it was too high??? Hot tub must have weighed 42,000lbs?By the picture, I am gonna say the container hooked the steel beam and pulled it out.
And I checked with big Dave Outwest. It was not a coop truck.

Gotta be more to the story... Wooden blocks front or rear to level deck to dock? Otherwise it makes little or no sense, unless it touched going in, hooked coming out...
