For those that are saying it is good to cross chains, you are assuming that the chains are connected separately to each side of the frame so that by crossing them you have created a cradle of sorts that will support the tongue if it comes off the ball.. My safety chains are both connected to the same point (rod running between bottom of frame sides). Crossing my chains just shortens them a bit, it does not create a cradle.
I think you will find that even if the chains are connected at the same point, there is a left and right. So crossing them will provide the cradle effect if needed.
