You can never tell when parked in a parking lot, or campground, when some jerk kid on a bike might come by and just do a try out - flipping the lever.
Xnorp (RIP) made a clip ring mod to prevent his jack legs from extending.
Its something that the manufacturer should do to.
Funny thing, the original Happijacs on my first 1998 Bigfoot had a spring latch: you wind the leg up completely and two spring loaded buttons inside the leg would engage holes in the outer leg, locking the jack up. When I replaced one of the jacks (rusted up) the holes were still there but no buttons. Now, no holes. So they had that idea once but gave it up.
I will say after using the feature once or twice I quit using it. It was a pain to have to go unlatch these while running each jack down, if you forgot then the gear motor would labor to a halt, can't be good for it.
In practice, the jacks work fine without any latches. It is a very rare event that they come down on their own, this is the first one I've heard about and it was due to a broken part. If you are concerned about someone messing with the lever, it is easily removed. Its only purpose is to disengage the gear motor if you need to wind the jacks by hand - again a rare event, and you can wind the jacks by hand back driving the gear motor without much additional effort in the event you ever need to.
