Think of your pin box as a pipe wrench with the jaws latched on to your frame. Your hitch pushes up on the end of the wrench and the frame is unaffected, even by big pushes from bumps in the road. The frame designer built in a safety margin to withstand those and somewhat larger inputs.
Now substitute a longer wrench. Are you sure the frame will be unaffected by those same pushes on a longer wrench? How much of the safety margin does the longer wrench eat up?
Do you feel lucky?
My 2¢
