Description
A 48-gallon DOT approved transfer tank and full-length integrated toolbox in a single low-profile unit, the RDS72774 keeps fuel and gear in one footprint instead of competing for truck-bed space. Built from 0.125 in. diamond plate aluminum with fully welded seams, it's engineered for the demands of farm, fleet, and contractor work.
A top-mounted sight gauge lets you check fuel levels at a glance, and a reinforced 2 in. female NPT coupling is ready for a manual or 12V pump. Built-in baffles reduce sloshing during transport, a rollover vent valve helps prevent spills, and a 3/8 in. FTP drain plug allows clean, controlled emptying. Aluminum construction prevents rust and protects fuel from contamination.
The integrated toolbox features a crowned lid with welded braces, two gas lift cylinders for hands-free access, and two stainless steel paddle handles with linked latches and a keyed lock.
Pressure tested before shipping. DOT approved for highway fuel transport. Made in the USA. Backed by RDS Manufacturing's 1-year parts and labor warranty.
Quality Assurance
Each tank is cleaned and pressure tested before shipping for leak-free performance.
