Actually, fridge is running on propane so why would battery drain so fast?
You don't have a SIG that indicates which trailer you have nor have you told us in your posts but presumably because you're posting in the Travel Trailer forum that means you have a TT with a DSI fridge. That in turn means that although the fridge heat energy source may be propane you still need 12 vdc to run the fridge electronics, the gas solenoid, and fire the ignition. Since we don't know the make / model of fridge you have we also don't know whether it has a 12 vdc climate control circuit that can be turned off and thereby reduce draw on the battery. Without these details we can only speculate as to what your issue may be.
