We are backpackers as well, so we tent to travel real light. We get away with a 35qt Waeco built-in
Food is no exception. The most our fridge is stocked with, for even multi month trips, is dairy.
Milk/yogurt/cheese/etc Beyond some home made frozen/vacuum bagged items, pretty much everything else is canned/dry storage food.
The wife is Italian though, and loves to cook, and has pretty well perfected the on the road cook-for-two. Always enough, never leftovers, and very few dishes.
Meat in the fridge? No way in hell. If I'm buying a steak on the road, It will be from a butcher, and cooked that night. :ylsmoke:
