Talking about drawers and opening on their own.....
I had reconfigured our galley base cabinet from 5 small drawers and a butcher block,
DETAILS & PICTURES HERE to 3 massive drawers which by my measurements, increased storage volume by 85%. As a result, the weight of the drawers increased tremendously, not just contents, but the drawers themselves. I initially had 5 double-magnet latches per drawer to keep them closed. Irene didn't like the "jerk" it took to open them, but that is what it took to hold them closed......or so I thought.
Our first major trip with our new galley, we were in Glacier NP in the south/east region on a scenic road that need some serious road work. In a hair-pin turn, between the bumpy road and the weight of the drawers, all 3 flew open with such force that all the track-stops broke and all 3 drawers ended on the floor with a huge crash. We spent the rest of the trip using our dinette cushions as insurance in-case the drawers popped open again for they would easily end up on the floor again.
In the end I installed all new tracks and kept 3 magnetic latches to hold the drawers closed while at-camp. Irene liked the gentle force to open them. I also added a locking button latch on each drawer which we have to remember to lock before moving the PC. So far so good.
