I’ll write more later on this, but in the meantime here is a video of the 78L ARB fridge/freezer we are looking at for the truck. In particular I like the lid removal, drain plug, ability to unplug and use as cooler, and the positioning of the controls. The 78l has enough depth to stand a 1.5l water bottle in it. To give you an understanding of its size, the fridge will hold 120 12oz cans (That’s 5 cases).
