Been on this board a year and never read any complaints about a gas refigerator...

If you wish, PM me for tips to help your freon fridge work better...

I'd give my wifes left arm to be able to install a Residential box in my RV. So far the only thing I could fit in there is a Haier 10 CF unit. It won't hold near as much as my 12 CF Nevercold quad door, which has already lost a board in constant use since August.

A gas refrigerator is incredible at Amudsen's station. Get it where it is hot and humid and Jeckyll turns into Hyde.

I'm confused. Gas fridges in an RV forum typically refer to ammonia absorption models that have no Freon.

He said that he could help make your Freon unit work better

I posted that Absorption units are not as efficient as a Compressor unit (use about 3x the power)

And I might have been a bit more specific in saying that COMPRESSOR UNITS (I said "they") No longer use Freon.. They use an alternative refrigerant, now days

You are correct that the absorption ones do not use Freon either, they use an ammonia and other stuff mix.

I improved the efficiency on mine yesterday.. Put in a pair of computer fans.. nice high volume computer fans in fact. Got 'em from All Electroincs so in addition to being nice, and high volume, and a bit noiser than I like (High volume make noise, not a lot not but I can tell they are running when I'm outside) They are LOW COST!! (like a couple bucks each as I recall without looking up the invoice)

Is the propane powered fridge still inefficient if you consider the inefficiency of generating electricity in a big power plant from natural gas or coal? These are 30 to 40% efficient. The gasoline or propane generator will be considerably less efficient than that.

I am pretty impressed at how long the RV fridge runs on 20 pounds of propane. It makes quiet boon docking possible.

What else about RVs is efficient? The water use of the RV toilet is a few times more efficient than a residential one.

A/C flow close to water heater isn't an issue in my rig. Maybe in some rigs it is. In my trailer this heater is far away in a storage nook, a limited air exchange with the room air.

Slots on battery box are needed for fumes venting rather than for heat exchange. You can't do much for battery cooling if it's outside, but you can (and should) use on-battery temp sensor when charging.

I think fiberglass insulation in RV walls are same 1.25" or 1.5" as styrofoam. Same R6 or R7 value. It's the missed spots (and framing if metal) that are a problem. Cold spot around my furnace was huge - all the outside furnace panel. I installed propane heater inside, removed the furnace completely, and put insulation in the wall there.

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.

Show me what in RV is build with energy saving in mind?
I just put insulating foam on furnace cover, where hot air from the exchanger was push against sheet metal cover exposed to the outside air.
Next project is electric element in water heater. The heater has Styrofoam insulation, but around plumbing there is a hole 3x8" with no insulation. So when you run AC, it is picking up the 130F air at WH tank. Then you need to run extra heat for water to stay hot.
Battery box on my camper is "cold" with slots venting to the outside. Yet, there is no insulation on plastic box, so another big heat exchange.
My camper is relatively well insulated with 1.25" of styrofoam, but check the R value on 3/4" of fiberglass some RV have.

Thought the issue was a discussion regarding Freon versus absorbsion refrigerators.

It was, and I agree about longevity. Absorption (or Adsorption) vs Absorpsion was not an issue 🙂

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.

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.
