What is the difference of refrigerator and a ice box in a RV?

In an RV, a refrigerator is an electric or gas-powered appliance designed to keep food and beverages cold using a compressor or absorption cooling technology, often featuring adjustable temperatures and larger storage capacity. In contrast, an ice box, or cooler, relies on ice to keep contents cold and typically has no power source, making it less efficient for long-term storage. Refrigerators provide consistent cooling, while ice boxes require frequent ice replenishment. Overall, refrigerators are more suitable for extended trips, while ice boxes are ideal for short outings or as temporary solutions.
