Bringing this one back from the beginning of the year to continue this discussion.
Anyone here have experience purchasing a dual zone fridge and then regret the purchase due to limited options with the 2 smaller compartments rather than one big compartment?
Looking specifically at a Dometic CFX3 75DZ
On our last build, we purpose ordered a non-freezer option in a NovaKool upright. (I realize this is mostly a discussion about the more efficient chest fridges but hopefully some of these thoughts are relevant)
We had a couple of reasons for the non-freezer decision. We had the same sized/brand of fridge in a prior build but with a freezer and found it took up a lot of room in a small fridge for a relatively small payload. This current same sized fridge w/o the freezer feels like it has away more useful space.
As we are mostly campers, we consider our fridge a huge luxury but it is also the biggest gobbler of power when running all of the time. I have really tried to keep our power requirements to a bare minimum. I know that modest is often associated with being boring but so be it. We had decided that we just don't need to have frozen food when we are on the road (no kids and their need for frozen treats helps). So with a pretty efficient fridge and a maintained decent cold thermal mass (we start off with frozen water bottles, cold beer, etc. and work to maintain it by restocking frequently), we simply turn off the fridge at night, something that simply can't be done where there is a need for maintaining below freezing conditions. We have a dedicated external BlueSea switch/breaker that is used after the last "door opening" of the evening occurs. By doing this, we reduce considerable draw on our system.
We just turn it back on in the morning and if there is any decent sun at all, our 200 watts of solar is more than enough to top off the battery while the fridge is running (We also have a dedicated AC battery charger but aren't near shore power most of the time as well as charging from the vehicle batteries). So basically, the fridge stays nice and cool with the door closed at night.
Maybe not an issue if your chest fridge/freezer is down on the floor but with our set up, the compressor makes a very small harmonic buzz while running (probably needs a bit more insulation in the cabinet) and as it is closer to the bed being an upright, we can hear it at night if the fridge is running. We don't run the furnace much at night either just because of the noise......
