I don't think Westfalia done a lousy job in choosing a front open door fridge. There were virtually no top open fridge in those days. Even if there was the cabinet design in the Vanagon would have to be arranged very differently to make work. The Vanagon conversion has many compromises and I think they made very good and balanced choices.

When you have the vehicle the size of the Sprinter to work with you have a lot more latitude. The fridge in the Westfalia James Cook is top load.

If I were to do the conversion in the Vanagon I will maintain the side load. Don't forget the specific heat of the food content is significantly higher than the cold air in the fridge. If the fridge is pretty full of food/drink the "cold" loss is not so bad in percentage.

That all sounds real good. What I see as the weak link is that the door opens and the cold dropps out. If the Westy fridge was just flipped over on its little backside it would become a good bucket to hold the cold. The refrigeration unit would work just as hard but the fridge would stay colder.
