OUr View is our first RV but we are toying with the idea of a smallish Class A. I am a bit concerned aout the handling and towing power. Our View has been upgraded to a 7 1/2 cuibic foot unit running auto with shore power and propane. It would be nice to have a 3-way reefer.

Note all the thrashing about with extra batteries, inverters and solar to have a residential refrigerator. The old absorption refrigerators performed well when install properly. Read the manufacturer's installation manual, it's an eye opener. Norcold did the RV word an injustice with their lesser materials and poor welds, causing fires.
How much room do you need in an RV refrigerator? Seldom are you far from a store.

No, the coach is plugged into the generator (or the generator is built-in) and the generator provides power to the fridge and multiple other sources in the RV. Depending upon the size of the generator it can power everything in the coach including the A/C's.


What I post is my 2 cents and nothing more. Please don't read anything into my post that's not there. If you disagree, that's OK.
Can't we all just get along?

If most of your camping is going to be without shore power I would not recommend a residential refrigerator unless you have plenty of solar and the requisite number of batteries to keep the fridge running.

All this talk about the number of batteries. It's not the nunber of batteries, it is the total amp hours that is important.

If you were to listen to a residential refer, you will find that there are periods of time when it isn't running. So, this means it doesn't need power 24/7. It is quite possible to have the refer on inverter power during the day, run the generator some in the afternoon/early evening and then (GASP) turn the refer off for the night period!

I have gone over 20 hours without power to the refer and everything was still frozen and the refer side was still within safe temperature limits for food.

Dometic, Furrion and now GE are all making AC/DC fridges using variable speed compressors that fit in the same space as the old absorption units. They're running around 8 amp hours average.

Our Class A came with a very large residential fridge/freezer. It's wonderful! Cools quickly, is very quiet, has a ton of capacity, and self defrosts, unlike my previous RV with an absorption style fridge. Even makes ice.

This rig also came with a Xantrex 1800W inverter, and 4 house batteries. That will keep it operating for a day without shore power, running the engine, or the generator.

If we are planning on dry camping for an extended period, I'll bring the Engel MR040F-U1 40 Qt AC/DC Portable Tri-Voltage Fridge/Freezer.

https://amzn.to/36Yp0id

[image]

It sips power, and will run a very long time from a 12V battery bank. It can be used as a fridge, freezer, or deep freezer, depending on how cold the thermostat is set.

The only upgrade I've done to our is to build an external digital thermostat. The stock analog dial gives no indication of what temperature "#3" setting represents!

Here's the thermostat build: http://2manytoyz.com/engel-thermostat.html

The Engel doubles as an emergency fridge during extended power outages at our house in hurricane prone Florida. It got some use last year!

Why think only about a generator? Solar recharging isn’t experimental or a toy. Most days you’ll be completely recharged with adequate system...batteries, controller, solar panels and properly sized wire. Start with an energy survey to determine your amp hour needs.


I agree with the above. One consideration if you do plan to use solar is that using solar with a residential refrigerator limits your camp sites to those with sufficient sun to recharge the batteries. If you prefer heavily forested camp sites, that could be an issue at certain times during the season even with the most efficient residential refrigerators.

It seems from what I have seen most of the Class A's that have the residential fridge has at least four 6 volt golf cart (GC2) batteries with about 200 amp hour each.

I have a 2016 Bounder 34T and replaced my OEM batteries with Costco/Interstate at about $90+ each. OEM's had a very early death. It has a Magnum 2000 inverter.

I was going to add some solar this year but had an emergency repair on the S&B.

We can go overnight running the fridge, TV, few LED lights, computer, furnace and still wake up without dead batteries. Have done several night stays running the generator for a few hours in the morning and again in the evening. Several times we have had low temperature around 30 to 35°.

The fridge is a Samsung RF-18 with an ice maker and for us it has been a good unit. There is a lot of negative reviews about them but been fine for us. Really enjoy the capacity especially when we got one or more of the grandkids with us. And frozen ice cream.

One of the best things for battery care, IMO, is get watering system for them and use it. I use a Flow-Rite [ur]https://www.flow-rite.com/ several places to buy including Amazon.

Before I replaced the OEM batteries I would turn of fridge, unplug any non essential items such as chargers and internet boosters ice maker and pray my power would last the night. The fridge would keep temp good enough as the door stayed closed.

Remember once the fridge is up to temp it doesn't run constantly! I don't have a residential fridge, but my buddy does. Neither of us dry camp. But if we were too, we would get a large amount of solar and more than 2 batteries, and definitely not wet cells! Make sure all the lights are LED, the previous owner of mine changed all of them out to LED. Power conservation will become second nature.
