The center of gravity of the piano would be no different if it were 2" off the ground as it would be 2' off the ground. If the piano were to be flipped?up one side, the only difference would be how far the piano would fall.

Wouldn't the center of gravity on a piano mounted on a flipped truck be quite a bit higher, making the whole thing less stable - if force is applied at the wrong place in the wrong direction? Granted, a tripod (which is what we have here) is inherently the most stable configuration, but suppose sufficient upward force were for some reason applied at one of the legs - wouldn't it be possible for the whole thing to tip over along the line formed by the other two legs - given such a high center of gravity? Now I know that this is not likely, but we have here a bunch of ignoramuses doing unpredictable things with a piano... Just musing while trying to postpone real work...
