RV Fresh Water Tanks - FDA Approved - Ronco Plastics - 51 to 100 Gallons

The Best RV Fresh Water Tanks for Life on the Road
When you're miles from the nearest hookup, clean, dependable fresh water isn't a luxury — it’s your lifeline. Whether you're building out a custom van, upgrading your travel trailer, or replacing a cracked tank in your motorhome, your system starts here....

At Tank Depot, we have one of the largest selections of food-grade, BPA-free RV water tanks available online — from compact 3-gallon tanks for minimalist builds to massive 200-gallon setups for extended off-grid travel. Each van tank is engineered for the demands of mobile living: lightweight yet durable, safe for drinking water, and designed to fit into tight, unconventional spaces. And because no two rigs are the same, many of our tanks come blank or semi-fitted, giving you the freedom to plumb your system your way — or take advantage of our custom RV fittings and accessories to get it done right the first time.

Why Choose Tank Depot’s RV Fresh Water Tanks?

Whether you’re navigating remote backroads or living full-time on the road, your water system needs to be dependable. At Tank Depot, we don’t just sell tanks—we engineer solutions that keep your RV running smoothly, no matter where you park it.

One-Piece, Seamless Construction
One-Piece, Seamless Construction

All of our RV water tanks are rotationally molded in one solid piece. This process eliminates seams—the weak points where cracks and leaks typically begin. The result? A road-ready tank that can take the bumps, vibrations, and stress of long-distance travel without compromising.

Food-Grade, BPA-Free Polyethylene
Food-Grade, BPA-Free Polyethylene

Our camper van tanks are manufactured using FDA-approved, BPA-free polyethylene that’s safe for storing potable water. You can count on your supply staying clean, odor-free, and free of contaminants—whether you're using it for drinking, cooking, or showering.

UV-Stabilized for Outdoor Durability
UV-Stabilized for Outdoor Durability

Many RV tanks are tucked away in undercarriages or mounted externally. That’s why our fresh water tanks include UV inhibitors, preventing material degradation from sun exposure—perfect for full-time RVers and anyone who camps in hot, sunny climates.

A Size for Every Setup
A Size for Every Setup

From 3-gallon tanks for van conversions to 200-gallon tanks for motorhomes, we offer one of the widest selections of RV fresh water tank sizes and shapes available online. Whether you're looking to save space or extend your water supply, we’ve got the right fit.
