A charged battery won't freeze unless it is extremely cold because the acid concentration in the electrolyte remains high. The problems begin when the battery isn't charged.
Do you have shore power to keep the converter/charger working? That will keep the battery up.
You don't want any 12 volt loads left on. If you lose shore power then any 12 volt loads will kill your battery that much quicker. Any time you draw your battery(s) down below 50% charge you reduce the service life of the battery unnecessarily.
Even with shore power charging I would consider disconnecting the propane leak detector when gone for extended periods of time. The propane leak detector is a constant drain. Some people install a main battery disconnect switch. If you do that you need to provide some way to keep the charger (or a charger) connected though.
Another thing to double check is to make certain that the TV antenna amplifier is switched off. Most which I've seen don't have an indicator light for "on" mode. The only clue is the switch position.
