Strap the ROAM 7-Gallon Water Tank to a compatible roof rack and keep camp cleaner-even through dusty trails, sandy beaches, and complex camp cuisine. This burly, high-volume tank naturally heats water in the sun, making showers, bike washes, and after-dinner cleanup easier and more comfortable. A six-foot hose and showerhead attachment are included, allowing us to easily get warm water from the tank.
