drivesitfar, There should be down force on the ball when the trailer is being towed. So putting weight in front to do that is a good idea if needed. Ball never comes off. I too put jack stands under the rear trailer corners when loading/unloading. I lift the trailer with a floor jack after loading to get the stands out.
Imagine what would have happened if you had been standing in the trailer when it let go. With the hatch open above you.
