The WaterPORT 8.0 Gallon Water Tank, formerly known as the Weekender, comes with mounts for your roof rack and will work with platform or cross bar style racks (with additional hardware). Both the tank and hose are made from food-grade plastics and are safe for drinking water. Pressurize this tank using the included fill valve and your standard garden hose, or use the schraeder valve with your pump or compressor.
