So, we are going camping for two, one week stints in July, but neither of them have electric hook-up. For weekends we've always made do with a cool box and freezer packs, for longer & with EHU we've hired a fridge (in France).
Can anyone recommend either a good high-performance cool box that works well with freezer packs, or a proper camping fridge - maybe a gas-powered one, or one that runs off the car battery (could it drain the battery if left on overnight?!). They all seem rather bulky for the actual food space that you get inside them....
