Description

The Custom Roto-Mold 30 Gallon RV Holding Tank is engineered for dependable performance in RVs, trailers, campers, and mobile systems. Crafted through a seamless rotational molding process from FDA-approved polyethylene, it offers durability and resistance to cracking and leaking. Its wide, low-profile form is suitable for installations with limited vertical space.

This tank has a 30-gallon capacity and is ideal for medium-capacity fresh, grey, or black water systems. It meets food-grade safety standards for potable liquid storage and features a seamless one-piece design for superior leak prevention. The low-profile configuration, with a 5.75" height, allows installation in restricted-clearance areas. It weighs 21 lbs, has a semi-translucent finish for visual fluid level checks, and is manufactured in Idaho, USA.
