I recently picked up the myCOOLMAN 44 fridge to sit in the back of my Prado.
The size is perfect for me and I really like the fact that I can plug into 12v from either end of the fridge.
I also like that I can see the current temp at a glance on the fridge, or via the app that connects via Bluetooth.
The fridge bag fits like a glove and helps keep the fridge cooler, reducing the cycling of the compressor.
I look forward to hitting the High Country and being able to enjoy icy cold beverages at the end of each day.
