Desert Captain.....I guess I didn't express it well. TYPICALLY, changing to a residential refer is done in larger motor homes that already have the room and battery power for it. They are very easy to install and about 1/3rd the price of a new Dometic or Norcold. I've done two in the last six months. The width and depth of a 12 cubic foot Norcold is identical to that of a Samsung. The Samsung is 4" taller and very easy to find that extra space. They require less venting and you do is plug them in.
Don't forget, I owned a Norcold and no matter how well it was working, an absorption type refer will NEVER perform like a residential refer. An absorption unit takes all night to catch up after a hot day. A residential unit stays cold no matter what the weather is.
Next time you put some meat in your absorption unit and have it in there for a day or two, stick a thermometer in it and check the interior temperature. The absorption units just can't hold a temperature for a long period of time. You may wake up in the morning and the refer is 32 degrees, but by noon and after opening it a couple of times it could be as high as 40 degrees. This is why the food never keeps the internal temperature of your best early morning temperature reading.
My statement isn't hard to prove. You certainly can't tell me that your RV refer works as well as your home refer!
Lastly, your Class C has a small 2 door unit, probably a 6 or 8 cubic foot and they always cooled well. Again, the larger motor homes with the big refers were just poorly designed and will never cool as well as a residential unit.
