Dometic (Waeco) is a huge global corporation, and makes all kinds of fridge / freezer equipment.
They are also OEM for many other brands, sometimes exactly the same units just a different sticker and wildly different price.
Some are very efficient (12V compressor type), and in the RV biz they've also sold a lot of the old three-way absorption style, including a propane option, where the 12V side is meant for while driving only.
Like US truck fridges, since unlike other developed countries, in many states they're still allowed to idle while stationary, no need to spend extra making them efficient.
So, when discussing fridges, best to use the specific model number to clarify.
