Fridge use with no elec during emergency?

I'd suggest to have another fully charged battery at hand or, if time allows, install a second battery. That way, you won't have to be a power miser and can last a few days on battery alone.

We can camp for almost a week using a single battery, with frig and hot water, if we are very careful about power usage. Nice to have hot water, but using that water pump uses a lot of power so "Navy showers" are shortened even more, lol!

If we will be dry camping for more than a few days, I carry a spare battery for our camper.

You have to really be careful about power usage... turn NOTHING on if you don't need to. Use battery flashlights / lanterns for interior light. Don't use the vent fan. If you need to use the water pump, turn it on only for as long as you need it (even the little lighted switch for the pump uses power!). Same with water heater - only turn it on 20 minutes or so before you need it. Yes, the actual heat comes from the propane, but the electronics needed to control it use power.

You might be surprised how long you can extend the life of your camper's battery.

If a friend has a generator you can borrow even for just a short time, you can use that to charge the camper battery - and take nice showers while it is running!

Swap batteries in and out with truck and charge with truck. Or maybe connect to trailer battery with a heavy duty set of jumper cables.

Thanks for the responses from all.

although I know a generator is handy to have in this type situation, I think I will try to do without. I have no other use for one, and really can't see spending that much money and effort on one for just in case. don't want to go into that discussion right now either.

Guess, if I lose power, I will just not use lights or anything else off battery, so that I can keep them charged to run fridge and water heater (if needed). Hopefully we won't be without power more than a couple of days, during a worse case scenario. I am not concerned about flooding here, but power dam and roads nearby could be closed. Survived the 100 year floods and 500 year floods brought on by rain from Tropical Storms within the last 20 years, so I should be good.

Glad I have an option, so I don't have to go to a shelter and share space with lots of others. I like my own space.

It's situations like this that a generator comes in handy.
I hope you have no damage or problems from the storm. At least you won't be without power during below freezing temperatures.

You will need 12 volts to power the control panel so a fully charged battery will be needed. If you conserve battery power I would think the battery will last a week, but if you use the furnace then maybe 1-2 days at most.

RV refers require a heat source (120VAC or propane) and control voltage (12VDC). Have both have a cold chil chest
