I carried a 20-lb bag of ice in my hand from one convenience store to the next about a half-block down- that was precarious, but didn't wreck, either.

I did tip my Worksman front-loader at speed once- hit about a 2" piece of wood with one front wheel. One discovery is that every loose item in or on your bike will go bouncing down the road at whatever speed you were moving beforehand. So ideally, have all the small stuff in tied-up bags or something rather than loose in the box.
