Designed for single-rear-wheel Mercedes-Benz Sprinter (2007–2025) and Ford Transit (2015–2025) vans, this tank delivers 22 gallons of certified potable water capacity in a compact, rugged package — perfect for off-grid living, vanlife, or adventure builds.

• Sensor-Ready Compatibility — Supports KUS S5U-15 (15") water-level sensor (sold separately) for accurate monitoring and convenient water management.
• Quick, Secure Installation — Comes with mounting straps for easy integration into your existing plumbing or custom freshwater system.
• Built for Road & Trail — Designed to handle vibration, pressure, and rugged travel conditions while maintaining leak-free operation.
