A cooler or fridge isn’t always needed. You can easily get freeze-dried or dehydrated food that doesn’t require refrigeration. If you want something fresher, German summer sausage, called Landjaeger, can easily last for over a week—even in desert heat with no refrigeration whatsoever. If you have the space, a cooler or a fridge is a great idea. This Igloo Ice Cube cooler typically keeps our stuff cold for up to three days, even in the desert in the summer. Beyond three days without civilization and we prefer taking a fridge, such as an ARB Fridge. Make sure to strap down whatever you take so it doesn’t bounce around.
