Battery life, fridge only

Thanks, will hook up to shore power in a couple days.

Without AC power your battery will slowly deplete although it takes several days just powering your RV fridge on propane. I have gone a week powering just my fridge, down to 12.1 volts when I finally plugged into shorepower.

Yes.

But as usual the true answer is it depends. There are more phantom loads on the battery than just the refrigerator. But typically a good battery will last about two weeks before going completely dead. If the battery is older it might not make it quite that long. If your battery is in fairly good shape though it should make it for at least a week.

What is your plan for recharging the battery after the two days? Are you relying on the tow vehicle to recharge it? Or are you getting an electrical hookup once you get to your destination?
