I would agree if this were just jawboning opinions back and forth, but we're dealing with apparent misstatements that shouldn't be left unquestioned, because people might believe what they're reading. The statement was made that by replacing a Norcold with a Samsung, trx430ex knocked $91/month off his electric bill. The reduction simply can't be solely caused by the Norcold, because it literally can't use that much electricity.

His signature says he has a 2006 Bounder, and in another thread, there are photos of his Norcold and it looks like all the other 12-cubic-foot Norcold 1200s I've seen (even though he says it's an 11-cubic-foot Norcold model 2008). Whatever--we'll assume it's at least similar to the Norcold 1200 that so many RVs come with.

This is a good example of where it's important to be careful. You're looking at the specs for the 2118IM, which means it has an icemaker. The specs are for maximum electrical draw, which happens when the icemaker is doing its heating, which it does only when it needs to drop cubes, and even then for only a few seconds.
The more accurate electrical draw would be the one for only the refrigerator, which is just above the one you looked at in the document you linked to. That one is 600 watts, which if running 24 hours a day would be 14 kwh/hour, nowhere near the 25 kwh/day that the $91/month electric bill represents.
And the 600 watts makes sense--that would be two 300-watt heaters.
But as I said, this isn't even the refrigerator he had that he said uses $91/month in electricity. The one he had uses more like 10 kwh/day when run nonstop, but he's saying it was using 25 kwh/day, which it simply can't do.

Well, most people don't consider that to be the "little" Norcold.
Regardless, it has two 225-watt heaters, for a total of 450 watts of heaters. But if it's like my Norcold 1200LRIM, the tag on the inside says that it's rated at 660 watts. Why? Because that tag shows the
maximum power it
can use, which would be when the icemaker is doing its heating. For calculating how much electricity it uses over time, it's important to realize it will only very rarely be using 660 watts, and that 450 watts is the number you should be using--that's what the heaters that make it run use.
For the record, the 450 watts is the number I use to calculate the maximum amount of electricity it could use in a day, and that's been verified by having a Kill-a-Watt on it in really hot conditions, when it's running nonstop--the watts used in 24 hours was right at the theoretical maximum.
