Make sure the frig has an inverter. Your TV will keep it cold while traveling. After 12 hours traveling or more freezer 0 and frig 38 just like before departure.

I run a 11 cu ft whirlpool in my toyhauler, I have 200 watts solar and 2 gc-2 batts I have been dry camping for 4 and 5 days at a time with no problems whatsoever, I run the genny for a couple hours at night anyways so it tops the batts so far I have never ran down the batteries past 60%, I'm using a 1200 watt pure sine wave inverter. Also it only takes an hour or so to get cold, it works much better in AZ in the campground than my old absorbtion fridge and I have an icemaker now to boot connected to my reverse osmosis system.

Residental fridge compressors are terribly inefficient and pull a lot of amps.

I don't see how any inverter and battery bank would keep up in transit, the tow vehicle don't deliver that many amps to the RV in the first place.

Best bet would be to get it cold before leaving home and don't open the doors until you are on shore power again.

Why I pulled my propane electric fridge last year and installed a Dometic Waeco compressor fridge. Works excellent, draws minimal amps and keep everything cold ot frozen


Maybe 20 years ago. Now they sip power. A couple 180 watt solar panels will provide all the power you need. Add a couple batteries for storage capacity. We replaced our absorption fridge 7 years ago. I would never go back.

This is 100% completely true and accurateif, and that is a very big if, it were 30 years ago. Today, nothing in this post is correct.

We've been using our residential fridge in our 5th wheel for 5 years now. NEVER had a problem keeping the temps at 38° and 0°. It cools down much faster than the propane models we've had in the past. We would NEVER go back to propane!

Our Suites is equipped with a 1,000 watt inverter and two 6 volt batteries, keeps the fridge running for at least a day (24 hours) without being connected to shore power or to the truck.

I use a 120V fridge. It is small and draws 80W, when running. As Pianotuna states, there is a duty cycle. Mine is 1:4. I have solar and many batteries but two 6V and a small charging source would provide a day of two for fridge power (depending on door interval openings). On the road, your truck powering through a 1000W inverter, will handle the load.

Single battery as a buffer and 1000 watt sine wave inverter will keep you powered and cold while in transit between destinations with utility power.
Not a big deal really.

The only caution I see is small inverters. There is no federal bureau of inverter ratings and they just plain lie about output. I put a small inverter in for house hold fridge and even though the specs said it would work, would not start the compressor in fridge.

I was unable to find the locked rotar amps for house hold fridges at the time.

I certainly see some day the absorption fridge in outs gets replaced with a residential fridge. My question is for those who have them do you have problems with the door opening in transit, if so what do you do to secure it?
