Some truck upgrades are about looks. This one is about usefulness.
Transfer Flow’s Tank & Toolbox Combos are built for drivers who want to go farther with less fuss. Whether that means towing an RV, hauling heavy equipment, heading toward camp, or simply spending less time worrying about where the next fuel stop might be. By combining extra fuel capacity with secure toolbox storage, these must-have upgrades help truck owners carry more of what matters while keeping the bed organized and ready for the trip ahead.

Available in 40- and 70-gallon configurations, these tanks can be set up as a refueling system for gas or diesel pickups, or as an auxiliary system on diesel trucks. Built from rugged aluminized steel, and proudly made in the USA, they’re designed for durability, convenience, and the kind of real-world utility that pays off every time you hit the road.
In the video above, Stephen from Transfer Flow gives a clear overview of how these systems work and why they’ve become one of the company’s most popular options. For drivers who want more range, more storage, and fewer unnecessary stops, it’s a practical upgrade with benefits you’ll notice every mile.
