RDS Liquid Transfer Tank / Tool Box Unit
RDS Liquid Transfer Tank / Tool Box Combos: Two Tools in One
When a long day in the field, on the farm, or at a remote job site demands both extra fuel capacity and secure storage, RDS Manufacturing delivers with their purpose-built Liquid Transfer Tank / Tool Box Units. These combination units are engineered to maximize the utility of a truck bed without sacrificing an inch more space than necessary — a philosophy that has defined RDS since the company began building aluminum products in 1975.
What Sets RDS Combo Units Apart
The defining strength of an RDS tank/toolbox combo is the uncompromising construction that goes into every unit. Made in the USA, RDS products feature fully welded seams and pressure-tested construction to ensure dependable, leak-free performance in demanding environments. The aluminum build isn't just about weight savings — aluminum tanks do not rust, protecting fuel from contamination. That matters enormously when you're transporting diesel, gasoline, or aviation fuel over long distances or storing it for extended periods.
Each tank comes with a reinforced 2" female pipe thread coupling for manual or 12-Volt pump use, a 2" fuel fill neck, drain fittings, baffles, a manual sight gauge, rollover valve (safety vent), and mounting tabs. The integrated toolbox side of the unit is equally well thought out: toolboxes come with linked stainless steel locks that also secure the fuel fill to prevent tampering, and two lift cylinders to hold open the crowned lid.
DOT-Approved and Ready for Real Work
RDS Manufacturing aluminum transfer fuel tank/toolbox combos are made in the USA and are DOT approved for transferring diesel fuel, gasoline, or aviation fuel. This DOT certification is critical for contractors, farmers, and fleet operators who must comply with federal transportation regulations when hauling fuel on public roads. A fuel transfer tank is used to move fuel from one location to another, such as from a gas station to a remote job site — commonly used by farmers, contractors, and workers who need to transport large amounts of fuel for their equipment.
For diesel users in particular, tanks can also be used to gravity feed diesel to supply additional capacity to a factory tank, with the use of an RDS Diesel Install kit. This makes the combo unit as useful as a supplemental range extender as it is a standalone transfer solution.
Capacity Options to Match Your Needs
The RDS 45-gallon transfer tank is a solid place to start, but you can find tanks with over 90 gallons of capacity. Whether you're looking for a compact unit to fit a standard short-bed pickup or need maximum capacity for a full-size work truck, there's a configuration suited to the task. Combination transfer tanks with tool box add-ons give you lockable storage for your valuables, with designs like an L-shaped tank that frees up more storage space in your truck bed.
For anyone who depends on their truck to get work done — and needs both fuel and gear within arm's reach — RDS liquid transfer tank and tool box combination units represent a smart, durable, American-made investment in productivity.
