Key Features & Benefits
Seamless Roto-Molded Construction: Unlike cheaper welded tanks, our roto-molding process creates a seamless, one-piece tank with uniform 0.180" wall thickness throughout. This manufacturing method produces superior strength and eliminates the risk of seam failures that plague inferior tanks.
OEM-Grade Quality: These are the exact same tanks installed in new RVs by major manufacturers. When you choose Elkhart Plastics, you're getting factory-quality components with proven reliability and perfect compatibility with industry-standard RV systems.
Low-Profile Design: At just 8.25" tall, this tank is specifically engineered for tight underbelly installations where vertical clearance is limited. The extended 61.75" length maximizes capacity while maintaining a slim profile that fits where taller tanks cannot.
Premium Material Quality: Manufactured from high-density polyethylene with fewer impurities than standard tanks, ensuring superior chemical resistance, durability, and longevity even under demanding conditions and temperature extremes.
Blank Tank Flexibility: This tank comes without pre-installed fittings, giving you complete control over inlet, outlet, and sensor placement to match your specific RV configuration. Install fittings exactly where you need them for a perfect custom fit.
Health & Safety Compliant: Manufactured to strict specifications that meet all necessary health and safety requirements for RV waste management systems. Safe for proximity to potable water systems and compliant with industry standards.

💡 Helpful Tip: Choose your holding tank capacity based on your typical camping style. For extended boondocking or full-time RVing, larger capacity tanks (40-42 gallons) reduce dump frequency. For weekend trips with hookups, smaller tanks (30-37 gallons) may be sufficient and save weight.

This is a blank tank without pre-installed fittings, allowing you to customize inlet, outlet, and sensor placement for your specific RV configuration.
