There are numerous options for an RV wine cooler if you look for the right specs.

First and foremost is that the cooler should be a "solid state" also known as "thermo electric" model and these models are very common - very typical of the “tabletop“ cooler variety. The traditional "compressor" models consume far too much electricity for RV use. These solid state models are completely silent and will pull somewhere around 10w-50w of power (that‘s a measly 1amp-4amps at 12VDC). Many of these coolers run on 12VDC but they typically will not actually say so in the ad or on the box. Thermo-electric models are powered from a transformer that converts 120VAC to something far less and in DC. You will need to look at the specific cooler and see what the transformer outputs by reading the label on the transformer itself. If the transformer says output is 12VDC just wire the cooler straight to your RV w/o the transformer and you have an ideal RV wine cooler! The other great advantage of these solid state models is they typically sell in the sub $150 range whereas the compressor models sell upwards of say $250. They are also very compact w/o the bulky compressor - and speaking of "green" they have no freon! The downside to solid state cooling is that they have far lower "heat capacity" (that's the technical term for what you are thinking is really "cooling capacity") than the compressor models. Meaning that they take a lot longer to cool a warm bottle and can not cool much more than 30 degrees, maybe 40 degrees below ambient temp.

I’ve seen these types of wine coolers at Costco/Sams even Lowes/HomeDepot. Many, many online sources and they come in numerous sizes. You might need to open the box and look at the transformer to find the ideal model.

Happy wine!
