Not a recurring problem. In fact, only one trip did we have any cabinet doors come open. Broke a bowl and dumped a box of detergent on the floor. Don't remember anything unusual, but must have hit a bigger bump than other trips. Like you, I use a velcro strap on all double doors. I only have a couple single doors and I do not strap them as they have never opened.
Only had one drawer that would open while traveling. But I adjusted the catch and it now stays closed.
Occasionally the pocket door will open if the latch strap comes loose. But so seldom I have not done anything about it yet.
