I am currently using my toyhauler for an extended period during hunting season which I will be using it off and on over the next month of so. During the interim periods it will be parked in a remote storage situation which I would like leave the refridgerator on but will not have access to electricity. If I start with a full 7.5 gallon tank (assuming 80% full after OPD) and run the refer only (no heat, waterheater, pilot lights, etc) does anyone have any idea how long I can safely run it without having to worry about running out and spoiling its contents. BTW it is an 8 c.f. and ambient air temps currently range from 40 - 75 degrees F.

Thanks,

'bob

Thanks for the response Dean. So, conservatively, I was hoping to be able to run it for about 2 weeks up near Flagstaff before I will be able to switch out tanks.

Your not worried about just leaving it run without you there for so long? I'd be worried it'd catch my trailer on fire. I don't like leaving mine for more than a few hours. Maybee I'm just being paranoid. When I leave my trailer for anylonger than over night I shut everything off, diconect the battery and turn off the propane at the tanks.

One more thing to think of is will your batteries run the fridge that long?

I'd be more concerned about running out of battery power unless you have solar panels to top off your batteries.

I don't know these things just seem like tinder boxes. What if you loose all your amonia and the burner over heats cause your not there to catch it, poof, fire.

I'm with you RedGuy. I didn't know that the refrigerator on my first 5'er had been recalled for fire risk. If I'd ever left it running for an extended period of time, who knows what would have happened. And who knows what's gotten knocked loose, worn out, rusted, etc. when it comes to these things. There are so many stories about RV's going up in flames, I'm a bit paranoid as well. Can't you just take the contents of the little refrigerator when you leave and bring it back when you come back? That would seem a lot safer than leaving the propane running to keep the fridge cold. Excuse me if I'm paranoid, but in my book, better safe than sorry.

O.K. So I went 16 days on a single tank before I switched out. That included 8 days total of combined use of the water heater and stove/range. As it turned out the trailer was intermittently used and there was no period of time more than three days between use by someone in our party and the batteries being charged.

Fortunately, is was not cold enough to require the use of heat of I am sure as the tank would of only lasted a few days


As far as being cautious/paranoid I guess I figure it to be a calculated risk. I don't think that Dometic would be in business very long if they could not build a sustainable product that you could not use for more than 8 hrs without a legitmate fear of fire. For me, I don't buy lottery tickets and I don't put my life on hold out of fear of one-in-a-million "what could happens". I took too many statistics classes in college to know better. If I am wrong, I figure that is what I buy insurance for.

Thanks for your responses and here's to the open road.

When we boondock we have fridge on gas for 2-3 days at least........as we have no power hook ups.
I don't even think about it.
If batteries need recharging we just crank up the Hondas!
The thing can burn down with me in it too - can't worry about everything!

If you want to do the math, here's the way:
Propane contains 91,690 btu per gallon.
Find the btu input for your refrigerator from the data plate.
Assuming no other uses or loss of propane, divide the refrigerator input btu into 91,690.
This makes it obvious the RV batteries will deplete before the propane supply.

Most recent RV refrigerators draw about 1.2A-DC whether they are operating on AC or propane.
