Metal is recycled. Ammonia is "disposed" into atmosphere. Big deal. There are more coal-burning power stations in one province of China than in the rest of the world.

Does it matter? Abuelo Mex must be bored, so he is asking whatever he feels like.

Somebody who's been a year on the board never read any complaints on propane refers? You can't conclude that propane fridge is reliable if you only use it 2 days a week 4 months a year - this is mere 1/10 of a year.

Average 120V residential compression will outlast an average ammonia powered by propane and will hardly require any maintenance during all that time. 12V compression "trucker" frigs like Novakool, Tundra, etc are different, condenser too small, compressor is different (12V) and/or control board finicky, you can't compare them with residentials, though I believe they are still more reliable than ammonia/propane fridges.

The rental house's 14 CF Samsung freon refrigerator freezer, all 14 CF plus freezer takes a greedy 157 watts to run it. At least that's what the EER sticker says. Twice as big, kept food in the 30's on a 117F day freezer managed to climb to a finger searing 2F.

There is a serious problem with energy waste with RV refrigerators. Couple that with disposal issues because of short longevity and indeed they deserve the "Brown" award "Green" is probably way off in the future.

I guess the 115 watt thermostat controlled AC of the RM2193 is more wattage than the 115 watt non thermostat controlled DC.
the 635 btu rated burner ~ 200 watts, no stat, no brain.

For the 37 years as a Tech, all the literature I have read and been trained with calls RV refers ABsorpsion technology. Doug

PS I always misspell as AbsorBsion

When someone made an error and didn't proofread. Picking at nits?

Seems that manufacturers abounded 12V elements once inverters become popular.
I remember removing the elements on 1980's fridge and when 120V element was like 110W rated, the 12V was 80W rated.
So 12V was not design to give equal cooling.
80W btw is 7.5 amp so you can calculate how long your batteries would support cooling at full blast.
I just had "nice" surprise on my household refrigerator. Even it is several years old, the inverter technology made into it.
Good thing inverter technology compressor gives better efficiency and quiet work.
Bad part it was the inverter board that blow on my fridge costing me $140 for part and 1/2 a day of studying the system.
New fridges run on R134a refrigerant btw. The same stuff you find in your modern car.

A quick google of refrigerator fires gives more info and pictures of compressor type refrigerators burned up than you can use- info on numerous recalls as well.

And the increasingly common use of R600a isobutane refrigerant in residential refrigerators brings with it an even higher risk of fire due to its high flammability. At least Freon is relatively inflammable, although when exposed to high heat it does produce deadly phosgene gas.

You are absolutely WRONG. RV Absorbsion refers that have a 12 volt Heat Element are for in Transit only power. The 12 volt heat element will drain any battery bank in less than 8 hours. There is a difference between ABSORBSION 12 volt and a 120/12 volt RV compressor type unit. Doug Below from the Dometic manual.

Wow, that's what I said. It's way too inefficient to be a realistic option for full time 12v operation off grid.
