Am I the only one this has happened to?

I've unhooked many times in the rain and also on sunny days on loose gravel. I have used both the plastic chokes and the metal expansion chock. I think of all those times when the truck was just high enough to get it off the ball. High adventure that. BUT I always use a piece of 12 X 8 X 16" under my jack that in itself makes for a safe disconnect and reconnect.
One my brand new TT I broke down and have the automatic system for leveling and disconnect. What a joy and it has a memory for what the height was for the ball disconnect.... life is good
