Most RVers understand that roof seams, vents, storage pods, and antennas must be sealed or coated periodically to keep the rain from pouring in. It is also common knowledge that RV holding tanks must be flushed out occasionally to prevent blockage. Likewise, all LPG-fueled appliances must be serviced periodically in order to avoid costly repairs and to insure that they operate at peak performance. It is likely that the absorption refrigerator is the most visible, most used, and yet least understood of these appliances.
