16 Gallon Custom Roto-Mold RV Holding Tank (MPN: H-379)

Description

The Custom Roto-Mold 16 Gallon RV Holding Tank (Part# H-379) is expertly crafted to meet the storage demands of compact RVs, van conversions, marine vessels, food trucks, and other mobile environments where space and weight are critical. Its slim linear form factor—only 7" wide and 8.5" high—makes it ideal for narrow passages, wall cavities, or under-bench installations.

This tank is made with FDA-compliant polyethylene resin and manufactured through a seamless rotational molding process, ensuring it resists cracking, leaking, and fatigue from road vibration or liquid sloshing. Certified under FDA 21 CFR 177.1520 (1) 3.1 and 3.2, the H-379 is safe for potable water and equally capable of handling grey or black water.

Perfect for lightweight builds and specialty installations, this tank provides reliability and peace of mind in a compact American-made design.
