One time when putting my front jacks down in manual mode, the bedroom slide started coming out once the jacks hit the ground. I ran it back in and it hasn't happened since.
I think someone said the hydraulics run off the same and maybe a valve stuck open or something like that.
As I said, it hasn't happened since and that was 3-4 trips ago.
