What exactly are the advantages to a residential fridge? Seems to be like Einstein and many engineers throughout history made our multi-mode fridge possible? Yay ammonia!

There are many counter depth models to choose from. Look online at Lowes and Home Depot. It gives a good rundown on actual measurements with doors and hinges removed, along with weight etc. which helps you plan on how to get it in the MH.
We have a French door Whirlpool with bottom freezer, water and ice maker in ours that the DW loves compared to our other MHs with the old 4 door Norcold.


The advantages are many: safety, efficiency, more space, proper ref/freezer temps 37/0F, no waiting days for it to cool, do more defrosting..to name a few.

Safety and convenience, yes, efficiency, no. If you are 100% in an RV park a resi would work, but if you want to boondock, not so much...

By efficiency, you can keep more food at the proper temperatures with less energy. Boon-docking? Many in these threads do it with resi frig without issues.

No worries, if it works for you, then that's what's important.



Making heat is a very inefficient use of electricity, which is required for cooling. Personally, I think it makes more sense to use a substance that is designed for making heat (propane) to cool my food unless I had an abundance of electricity and didn't care.


Now on the safety front, I TOTALLY agree that the propane fridges are dangerous as heck, and had one almost burn an old travel trailer down to the ground near the entrance to Yellowstone. Talk about scary! Luckily, I had fire extinguisher near the door because I knew something was going wrong with it.


I really would like to do some real world tests with a kill-o-watt, but haven't gotten around to it.



This video demonstrates what I was talking about with efficiency. Hard to argue with math, as long as his initial figures are correct or even ballpark.

I just learned that a DC compressor option exists:

Seems safe AND efficient!

DC compressor refrigerators have been around for years.

Check in any marine supply catalog.

Let me take a shot at this;

1. A sealer Compressor based system is infinitely more efficient than a propane/absorption system.
-Smaller Footprint
-More storage capacity in same space
-Interior circulation fans
-NO FIRE DANGER as there is no open flame anywhere

All this having been said propane is an option for off-grid use for sure. We made the change from propane to residential and couldn't be happier. Works great, we have 50% more storage and the freezer is much more usable.

I added a couple of batteries more much less than the cost of a new absorption fridge and we just got back from 15 days off the grid in Quartzsite and had no issues keeping the batteries charged and living like we were plugged in with a few solar panels.

Finally had it with our old domestic and went for the AC compressor unit from JC refrigeration. This thing works, fast, quiet and is super efficient. Customer service is the best I’ve ever encountered. It runs off our 3 solar panel system all day and night. Super easy to install and operate.

Thread is a bit old but we are making that swap. Her Crusader has a Dometic 2852 and has been unreliable, not starting back up after a power outage and the propane side not firing up. She found a Magic Chef 10.1 residential 120v at Home Depot for $380. Its dimensions will fit in the front door and we'll have to do some minimum trimming inside. This RV never travels and we have on our bayou property in NW FL so a residential makes sense for us. Tomorrow I'm going to look closely at what I need to remove the Dometic including the appropriate plug for the gas line. Next week we are planning to bring it down and do the swap. Wish us luck.
