I have to support others opinion here, Lee, that your door’s weight is no guarantee it won’t open on it’s own.
Like the others I’ve had a finicky latching door bounce open on the road. A BCS tech closed it after working in there, but apparently didn’t ensure both latches caught. I was aware of that particular door’s touchiness, but it wasn’t on his radar, and though I did a visual walkaround before departing I assumed all was okay and didn’t leg-nudge each panel. A bump between Bend and Redmond kicked it out enough for the struts to take over and lift it. Thank goodness a passing vehicle alerted me to it a few miles out of town as it’s forward location on the coach put it just out of my mirror’s view.
