Personally, I am a fan of an icebox in the fridge
section. There are zero
maintenance issues. We replace the ice (we prefer block ice) every 3 days or so. We also have an ordinary ice chest which we keep in the car or the bear locker. In the trailer ice box we keep meats and condiments, basically the things we use for dinner, thereby opening the door infrequently so as not to melt the ice too quickly. The ice chest holds produce which we use throughout the day. A tip for the ice chest: place a shelf extender rack (basically a wire shelf with 5" legs) in the ice chest, over the ice. Place the produce (or other items) on the shelf. As the ice melts the produce stays out of the pool of water. We also keep a few washcloths on the bottom to absorb the melted ice.
