Here's how I did it: To hook up raise the trailer hook the ball to the hitch. After the ball is secured in the hitch raise the trailer tounge higher, put the spring bars in place, with the height its easier to install the spring bar chains. Once the spring bars are connected lower the tounge and your done.
To un-hook: raise the trailer tounge to release the pressure on the the spring bars un hook the spring bars, lower the tounge release the ball lock, raise the tounge and pull the tow vehicle forward.
Just Remember to set blocks infront and behind the wheels before doing any of the above, just incase the trailer decides to roll forward or back...
