11 Gallon Custom Roto-Mold RV Holding Tank (MPN: H-576)

Description

The Custom Roto-Mold 11 Gallon RV Holding Tank (Part# H-576) is engineered to meet the requirements of mobile liquid storage applications in RVs, campers, trailers, and portable sanitation systems.

Built using seamless, rotationally molded technology, this tank offers outstanding resistance to cracks, chips, and ruptures caused by vibration, impact, or environmental stress. It is manufactured from FDA-approved polyethylene resin, compliant with FDA regulation 21 CFR 177.1520 (1) 3.1 and 3.2, making it safe for potable water as well as grey and black water applications.

With its extra-low profile design, this 11-gallon tank is ideal for installations where vertical space is severely limited—such as under-floor or under-bench compartments. The Tank Superstore team is available to help tailor the right solution for your custom setup.
