What temperature are you planning on using it in.
Those 3 ways, unless you get the blue freezer chescold types. only pull down 30 deg below ambient.
so if its over 30 deg, you wont be cooling as much as you would like to.
Ie temp in the 42 deg mark, your only going to cool to 12deg, not freezing.
We used a friends old brown chescold 32lt, and put white packing foam around it for extra insulation, and had good wiring to the fridge from the battery, as they pull a constant 10 amps on 12v, and had fitted 2 computer fans to the external cooling fins.
This would work
well in temps up to 35 deg, on 12v, then would not cool sufficiently.
On our trip with it, we used it for over 3 weeks, and ran it on gas each night out of the vehicle, and on 12v during the day.
Had to disconect it if we stopped somewhere for a walk etc, as it would flatten the 2nd battery pretty quickly.
It was our first fridge we used, and it kept everything frozen under the evap plate, and enabled us to travel without needing ice.
I found that it worked, but you had to put in cold stuff, or only 1 or 2 beers the night before to cool down overnight, if you filled it with warm stuff, it would not pull down in 24hrs, so it was no good for putting in warm fresh meat, and expect it to cool, or fill it with fish, and expect it to freeze it.
They just dont do that.
However they do work
well if you fill them with pre cooled contents, and only add small amounts of warm contents.
I would remove it from the vehicle each night, level it, and run it on gas.
We topped up the 2kg bottle about 2.5weeks of use, and it still had gas in it, but we were heading out, and needed to know it was full again.
Now we have a 47lt evakool. and a 20lt icecool esky as a crisper.
I fitted an agm deep cycle battery to
the tub, and the fridge will run fridge freeer setting for over 3 days on a standard n70 starter battery if you dont want to spend large on an agm battery. Can get n70s for under 100 on special if your lucky.
I havent run the 120ah battery down to see how many days I get out of it yet, but expect it to be far better than the starter n70 battery.
I don't have to remove fridge from car overnight, nor keep it level.
It pulls down temp very quickly, and i can freeze, or refrigerate warm contents quickly.
I find the battery in the tray, easier than having a gas bottle in the back, and easier to refill, by just running the car, or putting it on charge when at a park with power.
Even on a 45deg day, it will still freeze, and work
well.
Both work, but you have to learn how to work with them to get the best out of them, especially the 3 ways.
All depends on what you want to do.
We used a 3 way, enjoyed it, learned how to get the most out of it, but find the evakool 12v compressor fridge far easier, and more versatile for our camping needs.
