I was flipping through the owners manual and noticed that the cockpit fridge looks to be 12V only. Is that correct? If so, does anybody actually use the cockpit fridge? Seems like it would just be a drain on the battery.
Any of your 12V sources (fridge, lights, fresh water pump etc) will effectively be running on shore power when you are plugged in and your battery charger is on.
Good luck!
True, though I was thinking more of when we're away from the dock. Especially if we're spending the night on the hook. Not sure I want to run the generator through the night but if we have stuff in the fridge I want it to stay cool. Don't want the kids drinking warm milk in the morning

Or worse, having the beer get warm.
Well, we can't have beer getting warm
Obviously, while you're running the boat, a 12V fridge will not be draining the battery. When on the hook, you should have sufficient battery reserve to keep it going for quite a while without killing your batteries assuming you're not drawing a lot from other sources. A lot of people will run their generator for a while before calling it a night to get a charge on the batteries and many will also power down the fridge at the end of the night. Unless it is particularly hot, the fridge should hold its temp well enough through the night if it is not opened, though your mileage may vary.
I am not a huge fan of running a genny overnight because of CO2 concerns, though people obviously do all the time. Be SURE your CO2 detectors are in working order - they can be very temperamental. In addition to the two I have hardwired, I also have a battery powered home detector in the salon and a handheld unit with an alarm and readout. You would be surprised to see some of the readings I get depending on a variety of conditions, even with my genny off (from rafted-up boats running theirs).
