I have a 2015 Grandby with an Iota charger. Am I correct in thinking that i only need a 12v fridge and not a combination 12/120v because when I plug in for shore power the charger already converts the current and will power my fridge? I will use the existing 12v wiring that my 3 way is using currently. Seems like 12v fridge is less expensive than a combination 12/120v. I am open to any all bits of advice or suggestions.

Yes you are accurate in your analysis.

Our 2015 2 way fridge when plugged in to AC current the fridge switches from battery to AC current.

Saying that if it makes a difference in your choice of fridges.

I've heard some upgraded the DC wires to the fridge.

Thank you. What fridge do you have?

It is the largest Dometic that FWC installed that year

You are correct and this is exactly what I did last year after my 3-way fridge let me down on a trip. It'll help if you have a solar panel in case you are remote and stationary for a few days to balance out the fridge power consumption.

The IOTA will change your batteries and the fridge will be powered off the batteries not directly from the IOTA. In the case of a dual voltage fridge the IOTA will provide 120 to the fridge ac supply line.

Related to this, what is the most reliable 12v fridge?

We started (2011) with an Engel fridge freezer (top load) worked great but.... the wife wanted a door type fridge so in 2016 I installed the Isotherm 65 (Eagle FWC). It is a terrific fridge... low power consumption (we have solar) and incredibly quiet. I hate background noise and this hardly is noticeable even at night. Granted the freezer is small... always a compromise in camper space. Some folks with larger vFWC have the 130(?) which seems to be ideal if you have the space.

I have the Isotherm CR130EL and we are going into our third summer with it. It works great, and is very quiet. In fact, the main noise I notice at night is the relay click when it cycles on. By the second night i sleep through the click. The compressor itself is very quiet. I just wish the freezer compartment was about twice as large.

we have a Truckfridge 65 which works fine for two people for two weeks. Although it seems lot's of folks prefer a larger fridge, we find this one just the right size. very quiet compressor so little noise and the 200 watt solar runs it even in cloudy rainy weather fine.
