Some folks can abide a "marine" fridge just fine. Our luck is terrible with them. I've had the OEM Tundra, a DP2600 Vitrifrigo,
another DP2600, and now, a NOVA-KOOL RFU9000. The NOVA-KOOL is by far a better solution, although our brand-new installed before we left for the Bahamas for 3 months, fridge went warm 3 weeks into the trip. UGH!!
Had to have a replacement module air shipped in, fortunately, I travel with spare modules, and one of them kept it cool till the part arrived. Since then, I've replace the box thermostat. That's within 18 months of new.
That aside, the NovaKool is the only fridge that consistently keeps temps at 38F or under. The VF's would struggle to maintain 42, and spoilage was just part of life aboard. Slimy deli meats, stinky milk, limp produce. No milk was used without first sniffing under the lid.
Nearly all the "marine" fridges use the Danfoss/SECOP compressor and its proprietary control module. The modules can be frail. The newer ones had a firmware glitch that made them temperamental, mine just quit. If you cruise away from quick shipping, you should travel with a spare module that has the latest software, that is
NOT v.1.06.
The NovaKool is great with the freezer on the bottom, way better layout, and the air flow for condenser/fan is in front, so no issues with ventilation. Service is also from the front, so no need to remove the fridge to access the module or fan, the most likely points of failure. The thermostat is also a frequent source of problems, but accessible. The Danfoss compressor is intolerant of voltage drops, so it's imperative that you have a robust 12VDC source. My fridge supply is 8ga to insure that there's no voltage drop since the cabling is about 45ft round trip. Yes, the fridge only draws <10A, but - intolerant of low voltage. AND, it still must be defrosted every 2-3 weeks, particularly if you're in a humid climate. When ambients are in the 90s, the fridge struggles to maintain 38F box temps.
So, with all the foibles that go with a 12VDC/120VAC "marine" fridge for which you will pay absolute top dollar, you can purchase an apartment fridge that is frost-free, maintains temps that won't spoil food, and can be replaced with a new one from the local box store for a fraction of the cost the day it's needed. There is the issue with the inverter and standby losses, it might be worthwhile to use a small dedicated sine wave inverter for the fridge, you'll have to assess your inverter use and standby losses to make a decision on that score.
