Residentail refrigerators in motorhomes

First I would like to say that the peace of mind of not worrying about my refer causing my motor home to burn down is worth any consideration of a warranty. I purchased my RF197 on line through the Appliance Connection NY, free shipping and a warranty extended for five years and they knew that I was installing this in a Motor Home. But given the cost of replacing my Norcold with another Norcold or going the Amish route was not acceptable to us. I am not aware of this same problem existing in a Dometic brand, if I am wrong I apologize for that. But if I absolutely was determined to put a gas absorption refer back in I would try to go that route. I have said before I had visual evidence of my roof trying to catch fire at the top where it was vented and down along the sides where the flu was wrapped in insulation. Why does it seem it is always the Norcold and not the Dometic? Should this not raise an obvious question in the minds of people still arguing over residential versus gas absorption? This is such a large community of like minded people all going in different directions with different opinions very interesting isn't it....Good that we live in a country where we can have different opinions....
