Sometimes when I put something heavy in a drawer in my Travato like a laptop, the drawer would sometimes slide open when I was travelling even though it was latched. Here's why.
The drawer glides are mounted about an 1/8" off of the cutout for the drawer. Some of them have the wrong kind of screw, some are not tightened but mostly, if you weigh down the drawer it will push down on the glide and lower the latch enough that it won't hold well. Here's a pic.
I took a paint stirring stick, cut a small piece about 1/2" square and wood glued it in place under the glide. The glide is now supported and cannot flex downward and the drawer will not accidentally open. When you put the drawer back in you can't see any change and the drawer operates normally. Of course I did this to both the right and left hand glides of all drawers.
