For the adventurous, any ideas about testing this premise?

1) Install 3'4"  or 1" threaded screws, threaded into a 'nut' welded 
under the truck, under the legs...that can be lowered when the piano is 
in place...the result being, the screws, when lowered, would make a 
solid connection between the floor, and each of the legs....
