One thing to keep in mind with regard to "laws.". There may not be a "law" per se in which a violation would result in jail time.  I also can't say whether or not the NFPA Code shown above is a "law" with consequences for failure.  However, if you are relying on insurance to cover you in the event of a "fail," keep in mind that all insurance requires you to "mitigate risk," meaning if the fire department shows up to put out your trailer fire, sees the propane tank compartment is locked, then runs the other way as your trailer explodes, you have not "mitigated risk," meaning you haven't done what you can do to reduce the risk of explosion by making it possible to turn off the tank valves.  The insurance company will probably push back on your claim.  This happens, then people complain that their insurance company didn't cover them.  We have the responsibility to mitigate risk in our daily lives, like locking your house when you leave it, keeping your garage locked, securing your expensive possessions in some way; in short, showing that you did what you could to reduce the risk of fire, theft, etc.  Insurance is a "risk sharing" venture, meaning you do your part to reduce risk, and the insurance company covers you if you suffer a loss.  That's why I have a trailer lock; it's not so much to ensure my trailer doesn't get stolen, but at least I can say I "mitigated risk," so it's likely the insurance company will cover a theft claim without too much push back.
