Are you overstuffing the refrigerator? Remember, absorption refrigerators work best when there's air space around everything in the refrigerator. Too, an inside refrigerator fan works to push cold air around. I often see RV refrigerators that contain items that don't need to be refrigerated! Left-overs, protein, dairy and medicine requirements, do. Fresh fruits and vegetables don't need to be kept cold, just cool.
