Haven't done that but did kill the gate on my 07 Ram a couple years ago. Disconnected the FW ran in the house to do something, jumped back in the truck and took off forgetting to lower the tailgate.......DOH! That made quite the bang when it happened. Fortunately I found a nice clean gate at the wrecking yard the same color.
