49 Gallon Custom Roto-Mold Marine Water Tank (MPN: MW-461)

Description

The Custom Roto-Mold 49 Gallon Marine Water Tank (Part# MW-461) is designed to meet the demands of mobile fresh water storage in marine vessels, RVs, and specialty vehicles. Its low-profile rectangular form makes it ideal for installation in shallow compartments, hulls, or under seating areas where vertical clearance is limited.
