I think 359's trailer could have been tipped at Champs after a ball got stuck under it. However, there was only 25 seconds or so left after the ball was stuck and it was never rammed. With the surface giving so little traction the wheels just slide when hit, and it would probably require something getting under teh robots and a simultaneous hit of 2 or 3 robot on one against a wall, and that 1 would have to have a very high center of gravity. So all in al it's very difficult and probably never happened.
