I wonder about the propane leak...
Tanks have emergency shutoffs in the event of a sudden change in flow. They do work, I can vouch for it firsthand from when I totaled an old Prowler years ago.
The check valve would not engage unless the pigtail was ripped open between the Acme nut and regulator. If the only thing damaged in the crash was a gas line or two beyond the regulator you would still have a gas leak. That leak however would only be @19" WC or around 1/2 psi. You would smell it but it would not be the calamity the news media or some on RV boards would lead you to believe. Its not going to blow up a city block such as a high pressure transmission line ripped out with an excavator. If you lit the trailer line it would burn like a large candle.
