Popped off 2 cabinet doors already!!

OK....so we have our new awesome 5ther with slides....problem is the back cabinets come open when we drive over rough roads (not avoidable sometimes)....we CANNOT see the cabinets when we push the slides out, and voila! a cabinet door ripped off....we got the first one fixed with our punch list, but the second is all me to replace....we have a problem with many cabinets opening...is there a good mod or something we can do so that we ensure the cabinets stay closed?? No major biggie to put the door back on, but my wife is PISSED...and that is not good, as many of us know!! Don't want to tape it everytime we travel....just looking for a mod we can use with confidence....thank you!!!
