Description
The Custom Roto-Mold 21 Gallon RV Holding Tank (Part# H-586) is engineered to support the demanding requirements of mobile water and waste storage in RVs, trailers, campers, and mobile restroom systems.
Built using a seamless, rotationally molded process, this tank offers maximum structural integrity, resisting cracks, ruptures, and impact stress caused by vibration and road conditions. Made from FDA-approved polyethylene resin, it complies with FDA regulation 21 CFR 177.1520 (1) 3.1 and 3.2, making it safe for potable water and suitable for grey or black water containment.
With its compact footprint and low profile, the H-586 is an excellent choice for applications where space and clearance are limited. The Tank Superstore team is available to help configure fittings and installation details to meet your specific project needs.
