<h3>About RDS Manufacturing</h3><p>RDS Manufacturing has built a decades-long reputation as one of the most trusted names in aluminum fuel storage and truck storage solutions. <strong>Made in the USA</strong>, RDS products are engineered for working truck owners, farmers, contractors, fleet operators, and outdoor enthusiasts who demand dependable, rust-free performance in demanding conditions.</p><p>The foundation of the RDS lineup is its aluminum construction. Unlike steel tanks, aluminum does not rust, which means your stored fuel stays free from contamination whether you're hauling diesel to a remote job site or topping off heavy equipment in the field. Every tank is built from heavy-duty aluminum, features fully welded seams, and undergoes pressure testing to ensure leak-free integrity before it leaves the factory.</p><h3>Fuel Transfer Tanks</h3><p>RDS is perhaps best known for its <a href="/12679-rds-fuel-transfer-tank-55804">fuel transfer tanks</a>, which are designed to carry diesel, gasoline, or aviation fuel safely from the bed of a pickup truck to vehicles, boats, generators, ATVs, and heavy equipment. These tanks come DOT-approved and are available in a range of capacities — from compact units to tanks exceeding 90 gallons — so there's an option for virtually any truck bed and any hauling need. Many models include built-in toolboxes with stainless steel linked locks and lift-assist cylinders, making them a practical all-in-one solution for professionals on the go.</p><h3>Auxiliary Fuel Tanks</h3><p>For drivers who need to extend their driving range without stopping to refuel, RDS <a href="/12679-rds-fuel-tank-6268">auxiliary fuel tanks</a> offer a smart, integrated solution. These tanks are designed to gravity-feed diesel directly into a factory tank using an RDS Diesel Install Kit, effectively giving your truck a larger reservoir without a complicated installation. Each auxiliary tank meets DOT standards and includes features like a manual sight gauge, internal baffles to reduce fuel slosh, and drain fittings for easy maintenance.</p><h3>Truck Bed Toolboxes</h3><p>Beyond fuel storage, RDS produces a broad range of <a href="/12679-rds-truck-bed-side-rail-tool-box-15418">truck bed side rail tool boxes</a> and crossover toolboxes crafted from the same durable aluminum that defines their tank line. Whether you need a crossover box that spans the full width of your truck bed or a more specialized side-mount solution, RDS toolboxes deliver secure, weather-resistant storage for tools, tie-downs, and job site gear. The same commitment to corrosion resistance and tight construction that makes RDS tanks reliable carries over directly into their toolbox products.</p><h3>Why Choose RDS?</h3><ul style="list-style:disc"><li><strong>Made in the USA</strong> — all products manufactured domestically to consistent quality standards</li><li><strong>DOT-approved tanks</strong> — compliant with federal regulations for fuel transfer and storage</li><li><strong>Rust-free aluminum construction</strong> — protects fuel purity and ensures long-term durability</li><li><strong>Integrated tank and toolbox combos</strong> — maximize utility without sacrificing truck bed space</li><li><strong>Wide capacity range</strong> — solutions from compact auxiliary tanks to high-volume transfer setups</li></ul><p>From the farm to the job site to the open road, RDS Manufacturing delivers the aluminum tank and storage solutions that serious truck owners have relied on for generations.</p>
