Fridge use with no elec during emergency?

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

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.

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.

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.

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.

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!

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.

Big box grocers sell "dry ice" it will get through most emergencies.

You can dry camp for a few days without needing to recharge the battery. You probably will not be without power for more than a few hours.

Your propane leak detector and CO meter and refrigerator will use about 35 amp hours daily, or enough to discharge 1 battery in about 3 days. Only 1 hour of recharge time will get you enough power to make it 1 additional day.

If it is 'that bad' you might want to tow your trailer to a community with power - probably only 35 miles inland from your home. It is not likely that all communities will be without power for long.

When we had a bad earthquake in Northridge CA in 1994, I went to the valley to check out the home that my dad had rented back in the 70's and stopped at my cousins house. I left him my Coleman propane lantern, and it was the only heat and light that he had for 4 days. It took 8 days to get the natural gas supply working again. This was really rare, and his wife worked 20 miles south in Santa Monica, where there where no power outages, and she could shower at work before going home.

Good luck,

Fred.

As far as power consumption, you might want to get at least one LED bulb. It would use a lot less power and give you light. Or as others have said use flashlights. or cheap Harbor Freight LED stick on lights.

AS far as your question, yes you do need 12VDC power for control power. JMO
