I've seen this before and I wonder why. I lower the coupler onto the ball until I can latch it. Then hook the chains up with the little cheater bar that came with the hitch. Then lower the tongue and raise the jack.
People who have a equalizer type hitch must generally use the tounge jack to get their bars on. This is why I'm not that fond of the style. But in their defense they do tow well as sway control is built in.
