Did you know that by FederalLaw the compartment with your propane tank(s) cannot be locked, and generally the compartment with your electrical disconnect switches, and/or batteries will not lock electrically. Thinking about it logically the propane might need to be turned off in an emergency, perhaps by a first responder, by you, or another passerby who discovers a leak. The battery and switch doors are a little more arcane to my way of thinking. If an electrical fire were to occur you'd want to turn off and disconnect the batteries and the electric lock might not be working at that time. So, you'd need a key. Apparently battery theft or mischief is common enough to warrant locking and the inconvenience in an emergency. Those might be your compartments that aren't working?
Speaking of emergencies, how long would it take to find the correct size wrench and get it to the battery compartment, to disconnect them in an emergency? How much would it cost to buy an extra wrench of the proper size and keep it hanging in that compartment, just in case? If I was away from the motorhome, my wife would have no idea where to find the wrench to give to another camper to help her. Just a thought about preplanning.......
