15 Gallon Custom Roto-Mold RV Holding Tank (MPN: H-131)

Description

The Custom Roto-Mold 15 Gallon RV Holding Tank (Part No. H-131) offers a compact, ultra-slim solution for mobile waste and water storage. Its long and narrow profile is ideal for installations with tight vertical space—such as RV undercarriages, food trucks, campers, and boats—where maximizing length and minimizing height is essential.

Manufactured using a rotational molding process, this tank is crafted from FDA-approved polyethylene resin, meeting the strict requirements of FDA 21 CFR 177.1520 (1) 3.1 & 3.2. It is designed to safely store potable water, as well as grey or black water, depending on your system configuration.

The seamless, one-piece body delivers high structural integrity, resisting cracks, leaks, and warping caused by motion, vibration, and temperature fluctuations. Weighing just 12 lbs, the H-131 is easy to handle and install in a variety of tight-fitting locations.
