Thanks for posting. The cupboard doors aren't the problem. It the drawers-some of them-like the ones that migrate open behind the slide and the one under the oven, which don't like to stay closed during travel. The original owner used one of the couch pillows for the latter problem after the drawer had come open and marred the door under the sink. These ball bearing slides have such good closed retention when they are in your hands so something just isn't perfect when they are installed. I've shimmed them front and back and moved them forward and they work better, yet they still could use improvement.
These also work on drawers as well. I successfully use them in my TT

A lot of childproofing projects can be actively disabled once you're at camp and re-enabled when you go to breakdown camp. That would keep their annoyance factor down while you're using the camper but save you when you're traveling.
I have the "bulldogs" indicated in the 2nd post on the thread and still experience my drawers opening up. They are installed on the bottom side of the draw to save my hands.
