Yesterday I watched a guy unhook airlines and electric , pop the 5th wheel and start to pull the tractor away from an end dump trailer. I was yelling louder and louder as the hyd. line got tighter and tighter, but he stopped in time. So I was just pondering, "what would let go first"? and I thought, dang I bet someone on HEF has a story about that, or at least a theory. My guess is that it would leave a hell of a dent in the cab if the trailer side broke.
