Ivylog....Sorry...I didn't mean to side track the post with the residential refer.
I did a BUNCH of stuff to my Norcold to make it perform at a reasonable level. Something I learned by accident was there are two different thermistors for that refer. I was cruising websites looking to buy a thermistor one day and found a site that asked for the serial number. Apparently, there are two identical looking thermistors for the Norcold, but different part numbers. I ordered the correct one and my refer worked well again for awhile. Sorry, I can't remember the website.
I also added two additional computer fans to the exterior and one of the double fans to the interior. In weather under 90 degrees the refer would stay about 34 inside, but NEVER kept ice cream frozen, even though it made ice quickly.
As I said, sorry about distracting the post, but the Samsung was the best single improvement ever in my coach. All of the people on the Monaco forums installed it with the MSW inverter and four batteries and are doing just fine. I also think your idea of the costs to convert are a little high. You can get the SS model for $1209 OTD. If you can do your own install, just a few dollars in parts. Your charger issues don't make sense to me and if it's not working properly it seems it would be an issue for other things in your rig.
