Scary: footplate slipped out of position!

Another factor is if you have side-to-side pressure from having to turn as you're putting the trailer into position. So when the tongue pops off the ball, the trailer will want to shift sideways. We mitigate this by pulling the rig back and forth in a straight line (as much as possible) a few times before unhitching.

Now if we're concerned at all, we'll partially deploy the front stabilizers as part of the process. That way if the jack slips/adjusts in a bad way, the stabilizers will slow or prevent a complete fall.

Best regards,
Chris
