One thing I want to recommend is checking for a voltage between negative posts within the bank. I was equalizing one day using my Honda and noticed one battery very hot, the other luke warm.
I did some Google searches and learned it is common that one battery in the bank tends to discharge and recharge the most. I found 8-9 mV between my batteries. Despite using bus bars. Just the extra length of cabling, and compounding the problem was the longest cable was thinner caused a different voltage drop to the bus.
That small difference creates a big stress on that one battery and now you have to replace whole bank.
I led a wire directly between posts and now have just 0.3mV between them.
Regarding refrigerators sailboats have to have the most efficient.

A catchment tank could be used for a water cooled system. Although I would air cool.
