Great point. Personally were still running the old Demotic absorption fridge with no issues whatsoever. (spell check changed it to Demotic...I like it)
Fridge Defend is on our short list of must haves.
If we decided to go full time I'd upgrade to a residential no questions asked. For now the old Demotic and Yeti cooler are more than adequate, plus I like having the propane option.
Propanes cheap, L ion batteries and large solar systems not so much. To each their own, but my philosophy is if it ain't broke don't fix it. (unless it fits your plan)
So anyone here install a Fridge Defend system, and any words of wisdom doing so?

My Norcold never did a great job, I resorted to putting remote temp monitors in it to confirm temps. Kept cold blocks froze in the freezer and would move to fridge when temp started to climb. There was no rhyme or reason when it wouldn't cool. I just learned to live with it.

Then fate played a roll and the Norcold finally crapped out. I also agonized about the best option but decided to bit the bullet and install a Samsung RF18, which was not an easy task since I had to lower the furnace and shelf to gain enough headroom. This project was not for the faint of heart but I had some good resources, two other IRV2'ers did the very same thing and offered good advice. The job turned out well and I know I will be satisfied in the long run and will just have to learn how to best use energy to keep it running.
The one thing I was surprised at was how poorly constructed and installed the Norcold was. The key to the Norcold working is how well the absorption unit is attached to the box, in my case very poorly and I am sure there was a gap between the two surfaces which resulted in poor temperature transfer, hence the poor cooling.

A failed or poorly performing refrigerator creates a different decision making process than throwing money at a perfectly good refrigerator for the sake of reducing energy consumption by a few Ahís. There are also safety concerns with an absorption refrigerator for which there are relatively low cost solutions. There are also more absorption refrigerators still working today than have caught fire.

From what I've researched, some cabinet mods will have to be made regardless of the Alpine you have, and those cabinet sizes will limit the refrigerator choices due to height and depth. None of those changes, however, are difficult for the average handyperson.
Thanks for the shoutout.

I agonized over upgrading the existing (rather poor but performing) 1292 but in the end, I still had to remove the fridge from it's location to do the JC upgrade and I am SOOOOOOOO glad we decided to go residential.

I would be happy to talk you through what has to be done......there was almost no cabinet modifications needed and I'd be happy to talk you through what needs to be done. GE and Samsung have the same dimensions (GE actually 1/2" shorter) but in the end we liked the features on the GE better.

The Cost of the residential refer was actually cheaper than the cost of the JC 12V system and the same price as the AC replacement system.....a no brainer actually for us

Just send me a PM and I'd be happy to talk you through it

I did investigate fire suppression and fire prevention systems.
My takeaway was (without sounding too philisophical) that if you had one of those systems and ended up actually utilizing it, that meant you should have upgraded or replaced your frig to begin with.

It also seemed like i would just be moving the "can't sleep" paranoia problem over one notch.

Old scenario: "I hope the frig doesn't go on fire tonight....maybe I should take a flashlight and go out and inspect it. Is that ammonia I smell? Maybe it's just the Windex. What was that Sound? Was that the frig going on fire?"

New scenario: "Boy, I hope that if there's any overheating the ARP system will cut the power......what if it's not working correctly?.....maybe I should go out with a propane torch and heat up the pipes just to be sure it going to work. What if the suppression system doesn't activate? It's been in there for a while....what if it's lost all its pressure? Maybe I should go and tap on the pressure gauge....maybe the gauge is frozen. I think I just heard the suppressant leak out.....or maybe that was an airbag."

You guys are the best! We got to talking fridge replacement this morning (since we are getting our windows defogged soon). However, from the pic above, it looks like the emergency window hinges open. Is that correct? I don’t need to remove the entire window? If so, you’ve just saved me some money and aggravation. I can wait til the current fridge dies AND the budget allows.

Yes, the emergency window hinges at the top to fully open. I do believe that it can be removed if opened far enough and the "C" channel disengages. That was not made clear in Paul's photos because he propped the window open. I only mention this because the window is very heavy, and if swung out too far, could drop and break if one is not prepared for full removal.

Where are you getting the 6.2Amps from? That sees really high for a newer fridge. The fridges in the 70s and 80s used to be that high but most fridges now run and around 1 to 1.5 amps.

It depends on the coach model and year. Our emergency exit windows are on the driver side behind the sofa and on the passenger side in the bedroom.

Assessing risk and taking steps to minimize risk are important decisions for everyone. We all have different comfort zones and there are any number of things on our coaches that could turn ugly without notice.

Your original post mentioned only the power consumption differences between the 2 units that you were considering. It seems with your solar and battery setup you can easily power any refrigerator from your existing absorption unit to a residential unit without concern over draining the batteries. At least thatís one less thing to worry about.

Itís either good or bad that you have so many options available. From keeping the the original unit and modifying it in one way or another to replacing it with a residential unit. Whatever the choice, you have plenty of juice to keep it cold.

Whatever option you choose, it will be to your benefit to bring the refrigerator down to a cold temperature the day before, while plugged in, if possible.
Another point... Cold air is denser than warm air. When you open the fridge door gravity pulls the heavier mass of cold air out onto the floor... and as soon as you close the door the fridge has to start chilling the mass of warm air that replaced it.

So yes, a fridge with more food can recover faster due to the smaller air mass and the increased surface area of the cold contents helping to chill the warm air faster.

And naturally the fridge will use less energy overnight - the compressor may not run at all - because everybody is asleep and nobody is opening and closing the door!

If you install a fire suppression system in the engine bay and end up actually utilizing it, does that mean you should have replaced all the fuel and hydraulic lines to begin with? What if having those lines replaced is done incorrectly and causes a fire?

Installing additional safety systems simply means extra measures have been taken to reduce or eliminate damage that may be caused as the result of an equipment failure.

Other safety measures that can be taken with an absorption refrigerator would be to turn it off, or to AC, for 6-8 hours while sleeping. It is a minor inconvenience, but it is a no cost option.

Sorry those are 12V amps......120V would be 1/10th or .62 Amps

This does not include the Defrost cycle that seems to use about 15-20A (12V) for about 20 minutes 2X per day

Usually the door seals also need replacing. With mine the seals were no longer available except by ordering new doors for over $400.
Did mine the easy way, traded the 13 yr old rig on on one only 6 yrs old with Jenn Air refer.
