It's not just highway trucks. Numerous instances of quarry trucks taking down conveyors with a raised bed. My favorite is a quarry truck going downhill into an underground facility, bed up, hit the tunnel entrance and left the bed on the ground behind him. Sadly, it happened again, about a year later. Not the same driver. Newer off road dumps have interlocks between bed-up and transmission controls - restricts trans shifting into higher gears if bed is not seated. But, you can still do a lot of damage in low gear!
