Our coach still has the original Norcold all electric, AC/DC refrigerator. It still functions OK, but is getting kind of tired. It will cool down and keep things frozen in the freezer, but it takes a long time to do it. It is also getting kind of ratty looking. It is just time to modernize. My wife, Kathy, has wanted a GMC related item for her birthday each of the past few years, and has decided on a refrigerator for this year.

Since we like to dry camp on occasion, we would like to go with a heat absorption fridge and I would like any and all suggestions on brand (Norcold or Dometic), model number, two way or three way, etc. Also, if anyone knows where the best deals are, I would appreciate that information too.

Kathy would also like to know what the comparison is in terms of inside capacity between the old Norcold (7 cf?) and the newer models (6.3 cf).

Thanks everyone.

Carl, Wrestling with a very similar problem. First, the physical size of your current refrigerator and the hole that it inhabits, will determine the size of a replacement refrigerator. Unless you intend to do some major/minor woodworking to fit a new one, you need to have an measured idea of the physical space and purchase the new one of the same size (external size), that will fit within the same space. Smaller physical size may not matter much, but physically bigger is a PITA. Newer Frigs have better insulation, and you may get more interior frig room for the same exterior physical dimension.
I purchased a new refrigerator from Dometic, based on Dometic's listing of the new refrigerator as an "exact" replacement. Unfortunately, that is not true in 2 out of 3 dimensions. Both Dometic and Norcold list on their web sites the physical dimensions of their new refrigerator. Since I have a brand new Dometic, be aware, when they list the physical depth as 24", you must figure this 24" from top to bottom. Since the GMC body has curves, you must measure the depth from the very top of the refig space to the very bottom of the frig space. Can make for some very strange protrusions into the coach. Avion had to add a 1 3/4 border "trim" to install the Dometic RM66, which appears to be the standard for their coaches. The replacement RM2510 IS NOT an exact fit. And, I am not sure that the smaller one, RM2410 will easily fit there either.
A heat absorption frig will also require an access door, at the bottom of the frig area, to allow for air intake for the propane cycle. You also need an upper vent for air flow up and out of the Frig area. You also need to consider where you will run the propane line to the frig.
The old rule, "Measure twice, cut once," applies to refrigerators also.
It would help if you had listed both your coach interior design and the Norcold Refrigerator model number. Hope this makes sense and helps with the selection.

Tom Phipps, without a frig.

Thanks for the reply Tom.

The coach is a 26-2 floor plan with a full time bed in the back. It has the original Norcold in it, listed in the Maintenance Manual as a "seven and one half cubic foot refrigerator". My fridge compartment has a vented access panel in the wall and a vent in the roof. The propane compartment is in the right rear of the coach, so getting propane through the area under the bathroom sink, and above the wheel well will not be an issue.

My choices seem to be either a Norcold or a Dometic 6.3 cubic foot model. These seem to have the dimensions that are closest to the original. What I need help in deciding is whether a specific model or brand will work better in my climate (the desert of Southern Arizona) than another, specifically if there is any advantage to a two way or a three way.

Carl, just messing with ya. Sounds like your's is ready for a propane unit already, as our's was. 6.3 should fit right in your hole too. IF you need mesurements from mine let me know. Its a Dometic 3 way, 3 yrs old.

I know, Dan.

What are friends for? Laughing

The only dimension I think looks like a problem is the depth. Is it really tight at the top where the coach wall curves in? It should be easy to tee into the propane and run a line to the fridge compartment, other than that, you are correct, it is set up for a propane fridge.

Carl, I would think that there is not 10 cents worth of difference between the 2 major brands in their operation or cooling capabilities. The heat absorption cycle being what it is, there should not be any physics-related differences between the two. I would go with size of opening, and the features that the wife would like to have in her refrigerator. Wish I had measured my actual opening, before purchase.
You might get one of the solar fans to place high in the air flow of the refrigerator. Keeping the air moving up and out is the goal. I added a small muffin fan to the back area of my previous frig, and it greatly improved the cooling ability of the unit. The fan I used was from a 110v a.c. power supply and could move a lot of air out the top vent. Orientate the fan horizontally to move the air straight up, not aimed at the cooling coils. Did not help on 12v operation, but could have easily been feed by an inverter, not much ampere draw on a small muffin fan. I expect that you could find a bigger 12v fan and do your own thing with the fan. Cheaper than the solar fan sold at CW.
Tom Phipps, No frig yet

I wish that I could be of more help, however, I have sold my house & my refrigerator records are in storage,. I did buy a Norcold model N 641.3 (in 2004) and I love it. It is a 3 way and works like a charm. I contacted by internet every supplier that I could find for price and settled on a place with the lowest price and free shipping to my mechanics address (not my home address).
Getting the OEM refrigerator out was a SOB! Had to resort to using a saws-all to cut the frame into pieces.
Also my coach was not equipped for a propane refrigerator, so I had to tap into the propane tank, and install side and top vents, and build a "chimney" . All the extra work was well worth having a 3-way refrigerator.

Carl, some things I know and seem to be consensus of others, with a 3 way, the 12V draw is quite high, short battery life with engine off. Advantage is can drive down the road with propane off, like with rhe original fridge. 12v is really only usefull for maintaining temperature in an already cooled fridge. However, a 2 way fridge can be run on 110 V off a correct inverter going down the road. Some people don't like the propane on going down the road, and most places it is illegal to fuel with the propane on/fridge lit. Most new fridges need 12v even when on propane, so battery capacity "could" limit fridge operation.
Just what I think I know

Carl,

There are several Dometic refrigs that will fit the palm beach coach.

See: <http://www.dometic.com/enus/Americas/USA/RV-Products/refrigerators/
>

The DM 2620 Classic, DM 2652 Americana which we had in the coach we
just sold and it was a good unit and the DM 2662 Americana Plus.
These should clear the coach body without problem and allow for more
than sufficient hot air flow to the roof vent. The newer refrigs of
today are not exactly the same as you will be removing, but the
refinishing of the molding should be minimal in most cases.

The other choice is 2 way or 3 way? JMHO I do not see any value in
purchasing a 3 way unit for the GMC. Unless you have a very large
battery system with solar backup such as a DP SOB, then having the 12
VDC power for running the cooling is not an added cost that you need
to spend. All RV refrigs do require 12 VDC for control power to
operate when not plugged into shore power.

Take a look at these and of course the choice is yours to make.

that time.

OK, Thanks for all the info so far. The only reason I would think a three way would be desirable would be for being able to turn off the propane while driving, yet keeping the fridge in operation (albeit at a less efficient level). Some have advised just turning the fridge off while under way and others have advised using it in gas mode while driving (we ran the fridges in my father's SOBs that way all the time without a problem)

I don't think it would make sense to run a two way on 120 volt mode, through an inverter, while driving. The spec on these refrigerators says that they will draw 3 amps at 120 volts. If my math is correct, that works out to 360 watts. backing that off to 12 volts DC, through an inverter, it works out to 30 amps! right? The refrigerator will only draw 14.8 amps on 12 volts DC. Am I missing something here, or just having a brain fart? Electricity is not my strong suite.

I guess my next step is to decide who to order one from. PPL Motorhomes seems to have the best price, but (as I do with the GMC suppliers) I have a desire to support my local RV supply store too. I'll have to think about that for a while.

Thanks again. Any more thoughts?

Carl When i changed my fridge i did  not like how small a fridge i would have in a 2/3 way . Ended up with a 12 volt model  Draws 6 amp when condencer is running put a little extra insulation around it
Works good have 2solar panels and can leave it on weeks at a time Just put in fresh BEER and cold steaks and go during camping season leave all perishables in it usualy unplugged Freezer is on bottom i think it is 9cu feet have to keep it turned down or  BEER will freeze

Thanks Terry,

I have been doing the electric thing for three years now and am ready to go with the more dry-camping friendly propane fridge. I also want to stay with a fridge that will fit in the original hole. It seems that a 6.3 cf unit is the way to go.

Hard to believe that it has that much more interior space and it fits in the same cut-out, but apparently true. I think the 6.3 cf absorption fridge will be fine for our purposes (I'm not a beer drinker Very Happy ). Plus it will fit into my budget better. I plan on upgrading to solar at some point, but not enough to keep up with an electric refrigerator.

On some of the 3 way refrigerators, there is a gas burner , a 120 volt
resistance heater, and a 12 Volt resistance heater. The 12 V heater is
quite a bit smaller than the 120 volt and uses less current when it is in
operation. The one in my 78 Royale only works on 12 volt when the engine
runs, and is powered by a relay that closes when the primary side is
energized by the alternator circuit. It will keep up with an already cold
refrigerator, but has a difficult time bringing the box to the proper temp
when starting out. I guess the thinking is, either start with the propane or
120 Volt and then when you are traveling, the 12 Volt will keep up with it,
