Accidental uncoupling - dropping a trailer -

I actually haven't figured out how to do a pull test with the automatic leveling. I always used to do one with the landing gear about an inch above the ground so if it fell it would only fall an inch, but I can't do this with the hydraulic landing gear. It lowers one leg then needs backpressure to lower the other, and I don't want to pull test with the landing gear supporting weight.

Anyway, I now have the Reese Select 20K with the wrap around jaw, so I really just quit worrying about it.
