Elkhart Plastics 39 Gallon Low Profile RV Fresh Water Tank - Model 605W
The Elkhart Plastics 605W is a premium 39-gallon fresh water tank engineered specifically for RVs, travel trailers, and campers where vertical clearance is limited. With an ultra-low 5.75-inch height profile, this tank fits perfectly in tight under-floor installations and shallow compartments where standard tanks simply won't work. Manufactured by Elkhart Plastics, a trusted name in RV water systems since the industry's inception, this tank delivers the authentic OEM quality that discerning RV owners demand.
Measuring 54 inches long by 28 inches wide by just 5.75 inches tall, the 605W maximizes water storage capacity while minimizing vertical space requirements. This makes it ideal for boondocking, dry camping, and extended off-grid adventures where fresh water capacity is critical. The FDA-approved polyethylene construction ensures your drinking water stays clean, safe, and free from contaminants, while the durable molded design resists cracking, warping, and UV degradation even in harsh conditions.
Why Choose the Elkhart Plastics 605W Fresh Water Tank?
Ultra-Low Profile Design: At only 5.75 inches tall, this tank fits where others can't, making it perfect for under-floor installations, shallow storage bays, and space-constrained RV builds. The low-profile design doesn't sacrifice capacity—you still get a full 39 gallons of fresh water storage.
Authentic OEM Quality: Elkhart Plastics has been manufacturing premium RV water tanks for decades, supplying major RV manufacturers with original equipment. When you choose the 605W, you're getting the same quality tank that comes factory-installed in new RVs, not a cheap aftermarket imitation.
FDA-Approved Materials: Your family's health matters. This tank is constructed from FDA-approved polyethylene that's specifically rated for potable water storage. Unlike inferior tanks that can leach chemicals or develop odors, the 605W keeps your drinking water pure and fresh.
Maximum Capacity for Boondocking: With 39 gallons of storage, you can extend your off-grid camping adventures without constantly worrying about running out of water. Perfect for dry camping, boondocking, and remote locations where water hookups aren't available.
Built to Last: Elkhart Plastics uses rotational molding technology to create seamless, one-piece tanks with uniform wall thickness and superior strength. This tank resists impact damage, temperature extremes, and the constant vibration of road travel.

Many RV owners choose this tank when upgrading from smaller capacity tanks or replacing damaged original equipment.

Whether you're building out a Sprinter van, converting a school bus, or designing a custom teardrop trailer, this tank provides professional-grade water storage in a compact, space-efficient package.

Installation and Compatibility
Installing the Elkhart Plastics 605W is straightforward for anyone with basic RV maintenance skills. The tank features standard fitting locations that are compatible with most RV plumbing systems. Before installation, carefully measure your available space to ensure proper fit—remember to account for plumbing connections and allow adequate clearance for thermal expansion. Secure the tank using appropriate mounting straps or brackets to prevent movement during travel.
This tank works seamlessly with standard RV water pumps, fill systems, and drain valves. For optimal performance, we recommend pairing it with quality Elkhart Plastics tank fittings and accessories to ensure leak-free connections and long-term reliability. Always use food-grade plumbing components and sanitize the tank thoroughly before first use.
