Prevented one of those disasters a few years ago at a Maryland Campground. We were alread set up and sitting by the fire after dark when the neighbors showed up. Nice 5th wheel being hauled by two nice ladies. They managed to get backed into their site just fine and were having some problems getting unhitched. I'm sitting there watching them struggling to unhitch for about 3 minutes and finally I said to the wife, I can't sit here and watch them roll that thing into the lake. I politely asked if I could help and they gladly accepted.
First, do you have chocks to put under the trailer wheels? Yes! Oh we forgot about them! They put them in place. And then I instructed them on backing up off the pin. You should have seen the look on her face when she reached for that handle and it easily pulled out. I'll bet they never forgot that lesson.
