Camco's 8-Pack 4 oz. RV Holding Tank Treatment sounds pretty convenient for RV owners. Each 4 oz. bottle is designed to treat 40 gallons of holding tank capacity, which makes it easy to manage without any mixing or measuring. It helps in preventing odors, lubricating sensors, and is compatible with all types of holding tanks and septic systems. Plus, it uses a specific chemistry to control odor development effectively.
