Most of them had reviews about how hard it is to make them stay in place with heavier monitors. I can't even imagine what happens if I forget to fix them very carefully before moving and break hard while moving.

But then, of course, I am half-joking. I actually did find myself doing that research but after realizing the sitcom scene I put myself in, I gave up quickly: I don't even have a driver's license, and I'm researching the monitor-mount situation for a caravan-life?!

When searching here in the US with query “vesa monitor wall mount” I find a bunch of ones which would be secure and work well (multiple of which I own). Maybe that’s not the case where you live (assuming you’re either European or Aussie based on the phrase “caravan-life”, but guess that’s not an accurate assumption possibly).

I'm gonna guess Europe based on the "no drivers license" comment.

Your guess is right, I'm living in Germany. But I think I'm in the minority here - I really don't know any German who is in their twenties without a driver's license. I'm not German though and I used to have a license back in Istanbul, which is not valid in Germany. I didn't bother getting a license here because you can get a Bahncard from Deutsche Bahn, which covers 90% of one's public transportation needs. Maybe it's a similar story in other European countries but I think most people still get a license just in case.
