25 Gallon Custom Roto-Mold RV Holding Tank (MPN: H-100)

Description

The Custom Roto-Mold 25 Gallon RV Holding Tank (Part No. H-100) is expertly designed to provide efficient and durable fluid storage in mobile applications such as RVs, trailers, campers, concession trucks, and marine vessels. With its extra-low profile and robust construction, this tank is ideal for tight installations where vertical space is limited but performance cannot be compromised.

Constructed with a seamless rotational molding process from FDA-approved polyethylene resin, the tank meets FDA 21 CFR 177.1520 (1) 3.1 & 3.2 standards, ensuring safe containment of potable water. Its one-piece design reduces the risk of leaks or structural failure, offering excellent resistance to cracks, stress, and impact from vibration and shifting during transit.

Measuring just 6 inches in height and 58 inches in length, the H-100 provides 25 gallons of capacity in a wide, shallow format—perfect for underfloor compartments or specialty vehicle builds requiring low-clearance storage.
