Using the Ford hitch mentioned by Golden_HVAC, the design only accounts for 666 ft-lb of torque. Compared to the 800 ft-lb of torque the 200# load at 4'. These are only static (non-moving) measurements.
Now, when you throw in the momentum which is also multiplies due to the length, you will exceed the hitch rating with much less weight. Good example would be to hold a 20# weight next to your shoulder for two minutes. Now hold a 2# weight at arm's length for two minutes. Pretty easy huh? Now do the same, but this time while jumping up and down. Understand better?
