Recently a purchased a five day cooler from Walmart. It was relatively cheap. I chose the 50 quart size. Because I am a diet Coke addict, I tossed a couple of 12 packs of pop into the cooler and filled it with ice. I stored it the back of the old Cavvie (Cavalier) that I drive. The fall Iowa temperatures reached 60-65 each of the next five days.
Day 1 – Almost all the ice was left.
Day 2 – There was a fair amount of water but the pop stayed cold.
Day 3 – There was a majority of water but the soda pop was quite cold.
Day 4 – All ice was gone but the water was still cold. The soda was drinkable.
Day 5 – The remaining water was not cold by any stretch but the soda was cool enough to drink.
I made some conclusions about using this 5 day cooler in lieu of a fridge for vandwelling.
1) It might be better to freeze blocks of ice (in a gallon water container). No water and no sloshing sounds.
2) Since I have access at work to ice and a freezer, I will try rotating two frozen gallon jugs (one at a time) every 3 days to see if I can maintain refrigeration.
3) I can fill the gallon jugs with filtered water for a delicious drink if needed.
This cooler works reasonably well for a vandweller who has access to ice on a regular basis. I can pull this off and always have cold drinks and food available.
