LOL dont count on that working for you. One of my neighbors lost his home last week due to a faulty propane tank and yes it was a new one. I was sitting the border line up heading out of town when a breaking news story came on that there was a house fire up on the hill and the gave the name of the street & that it was so big it could be seen from all over Vancouver - had to phone another neighbor to make sure it wasnt my house. Good news is that no one was hurt but the house is gone.

For more than an hour without draining your battery and the alternator has to work to hard to use it while traveling.

Are there better 3-way fridges now?

I am using ice now because the propane flame is still in the wrong place. And I don't like having propane on all the time as a general thing.

Brooke, what gauge of wire do you have running from the tow vehicle battery to the trailer battery? If it is too small, your trailer battery won't charge due to the voltage drop, especially with the refrigerator on 12 volt option.

10 gage.

Charges my battery to 13+ quickly as long as the 12v fridge is not draining the battery.

Right. The fridge draw amperage causes a voltage drop in the 10 gauge wire severe enough so that the charging voltage at the trailer battery is inadequate. It might be worth your while to add a second and/or heavier wire to allow you to run the fridge while the tow vehicle is running. You really can't run a 3 way fridge off the battery alone.

You could measure the voltage at the battery with the tow vehicle running with and without the fridge turned on (12 volts) to prove this to yourself.

The fridge is connected to the battery with the recommended 14 gauge wire and it draws down the battery very quickly.

The DC option doesn't keep the fridge very cool anyway. Ice works better and it is easy. I have dedicated the middle shelf to an ice holder and it works for 2-3 days depending on the weather.

AC is best but I haven't gotten any hookup sites this trip.

Sounds like you have a solution that works for you.

Keeping small ice packs in the freezer while running the fridge at the campground and then just transfer then into the fridge beside dairy products & meet to keep them cold while on the road and dont open the fridge!!!

Yes some of the much newer fridges are a lot better on battery power.

We leave the camper plugged in all the time, that way all the ketchup and mustard etc can stay in there. Then, although the longest trip we have made is 3 hours we just load it up and unplug right before we leave, everything stays cold and we have never had a problem. I am just not comfortable with the propane on while driving.

We do the same thing. The fridge is running 120 at the moment. The difference is our longest trip can be 2 days. Even then I don't worry too much about it. The fridge stays cool enough for that long, except in 90°+ temperatures.

I also keep the trailer plugged in and the Fridge running on AC since I replaced the old original converter with one that has a smart charger. It seems to be easier to keep it cold than it is to make it cold.

Carol, as you say, you can blow the place up. And a few people including yourself with it. We have no desire to take such a chance when we can use ice packs for travelling. By the way, Good Sam gets lots of calls for refrigerator fires.

The Dometric is supposed to shut off the LP supply if the pilot light goes off going down the road.But...your propane tank will still be open.As they say...Manure Occurs.
I travel with most of my perishables in coolers w/ ice,keeping the dometric running on 12 volt while driving,then switch back to 110 or LP upon destination.And I agree...the last thing I want is to be involved in an accident with pilot light on and a propane tank open.

We pretty much always get the fridge cold on AC at home. For short trips in cooler weather, I don't turn the propane on until I get to where I am going. For longer trips and hotter weather, I always turn it onto propane (except of course where not allowed).

No way I am letting my ice cream melt or my beer get warm.

Most folks we camp with do the same too.
