Description

The Custom Roto-Mold 123 Gallon RV Holding Tank (Part #H-331) is purpose-built for demanding mobile storage needs, including RVs, food trucks, marine systems, trailers, and specialty vehicles.

Manufactured using a seamless, one-piece rotational molding process, this tank offers outstanding resistance to cracking, leaking, and road shock damage.
