Tank for Promaster 3500
Perfect 10/10
We are always striving for better space-saving ideas, and this undercarriage tank is just the ticket! This tank is designed to fit snugly around your Promaster’s framed undercarriage; these tanks are the perfect solution for your off-grid water requirements.
Composed of high-quality, BPA-free, food-grade approved linear low-density polyethylene, this tank can also function as freshwater storage. We've created a complete Freshwater Fittings Kit that includes everything you need to turn this tank into an undermount freshwater reservoir.
Complete your off-grid water management system by pairing this undermount tank with our 22 Gallon, or our 32 Gallon Promaster Wheel Well Water Tank. Worry less about water management, and spend more time adventuring!
