We also had an issue with the drawers ALWAYS opening while traveling. I replaced the plastic drawer locks and we still had the problem. Two times I had to reassemble the glides.
I decided to drill a hole in the back of the drawers, and a hole in the wall that separates the drawer area and the kitchen sink. I went out and purchased 2 (3") eye bolts and 2 nuts/washers each. I mounted the eye bolt on the back of each drawer with the EYE part of it sliding through the sink/drawer wall. I cut 2 pieces of dowel rods and when we travel I put the dowel rod through the eye bolt and it keeps the drawers from opening while traveling. Sorry the picture came out a little dark, but you get the idea. Click on the picture to get a little better view of the bolt.
So far it works GREAT
