Description
The Custom Roto-Mold 78 Gallon RV Holding Tank (Part# H-540) is engineered for high-capacity mobile liquid storage in RVs, campers, trailers, and mobile sanitation setups where a broad, low-profile tank is needed.
Constructed with seamless rotational molding, this tank delivers exceptional durability, resisting cracks, chips, and impact damage even in harsh conditions. It is made from FDA-approved polyethylene resin and complies with FDA regulation 21 CFR 177.1520 (1) 3.1 and 3.2, making it suitable for fresh water, greywater, or blackwater applications.
Its wide 50-inch square footprint and slim 9-inch height make the H-540 a great solution for floor-mounted or compartment-based installations that require significant storage volume with low clearance.
