Dangerous Pranks
There are dangerous pranks I read about today on RV quilters facebook page. Both happen at night. "Kids" go around closing the bar that goes in front of doors. Doing that makes it nearly impossible...

Another thought...if closing the grab handle against the door really DID trap people inside (which, as others have noted, can't happen these days because the units have emergency exits), I'm pretty sure either some government agency would have banned them (think 'lawn darts') or product-liability suits would have bankrupted the manufacturers by now
