The main reason for for the size upgrade, my current fridge is fairly small internally. We decided to get a small countertop fridge for the awning instead. 👍🏽Ithink the absence of any replies suggests no one has swapped acaravan fridge for a domestic one.
From a practical point of view I doubt you would find any domestic fridge would fit in a caravan without having to make some quite major changes to the caravans furniture.
Why not just use your caravan fridge on electricity?
