55 Gallon Custom Roto-Mold RV Holding Tank (MPN: H-85)

Description

The Custom Roto-Mold 55 Gallon RV Holding Tank (Part No. H-85) is engineered for maximum strength and dependability in mobile water and waste storage applications. Designed to perform in the demanding environments of RVs, trailers, food trucks, and marine vessels, this tank offers a large capacity in a slim, low-profile footprint.

Constructed using rotational molding from FDA-approved polyethylene resin, the H-85 tank complies with FDA 21 CFR 177.1520 (1) 3.1 & 3.2 standards, ensuring safe storage of potable water. The seamless one-piece construction eliminates common weak points and provides long-term durability against cracking, deformation, and impact damage—even under constant vibration and movement.

At just 10 inches tall and over 51 inches long, this tank is ideal for shallow compartments or underfloor installations where vertical clearance is limited but capacity is essential. Proudly manufactured in Idaho, USA, the H-85 combines functionality, strength, and quality workmanship.
