100% Authentic OEM-Quality Construction
These rotational molded fresh water tanks are crafted to meet or exceed factory standards, making them a perfect upgrade or replacement for your RV, horse trailer, or marine vessel. When you need reliable water storage, trust the brand RV manufacturers rely on.
Premium FDA-Approved Material
Made from high-quality, durable polyethylene that's fully approved for safe drinking water storage. This food-grade material is better than many stock tanks installed in factory-built RVs, ensuring your water stays fresh and safe for consumption.
Seamless One-Piece Roto-Molded Construction
Elkhart Plastics uses an advanced roto-molding process where high-density plastic is rotated and molded into shape. This creates a seamless tank with walls of equal thickness throughout—no weak spots, no seams, no joints. The result is superior strength and leak-proof reliability that outlasts and outperforms typical OEM tanks.
Stain, Corrosion, and Rust Resistant
Designed to stay clean and functional even after years of use. The non-porous polyethylene surface resists staining and won't corrode or rust like metal tanks, ensuring your water stays fresh and your tank stays dependable season after season.
Enhanced Durability for Demanding Conditions
Built tougher than many standard factory-installed tanks, this fresh water tank can handle the bumps and bangs of the road without compromising the security of your water storage. Fewer impurities in the material mean stronger walls that won't crack or fail when you need them most.
