RotopaX: Built for the Trail, Engineered to Last

Few brands have earned the loyalty of the off-road and overlanding community quite like RotopaX. Founded in 2007 by a family of outdoor and power-sport enthusiasts based in Logan, Utah, RotopaX was built on more than three decades of multi-generational plastic manufacturing expertise. That deep roots in materials science shows in every product they make — containers and mounting systems designed to keep adventurers fueled and supplied no matter how remote the destination.

What sets RotopaX apart from conventional jerry cans and plastic jugs is their proprietary rotational molding process. RotopaX fuel storage cans are produced using a patented three-layer roto-molding technique with a specially formulated plastic barrier material, making them the only rotationally molded EPA and CARB compliant fuel containers available for sale in the United States. The result is a container with extra-thick walls, leak-proof construction, and a sure-seal gasket that keeps spouts secure even on the roughest trails.

The genius of the RotopaX system isn't just in the containers themselves — it's in how they integrate with your vehicle. RotopaX fuel tank attaching hardware includes a full ecosystem of Standard Pack Mounts, DLX Pack Mounts, LOX locking mounts, roll bar mounts, and spare tire mounts, each designed to attach firmly to virtually any flat surface on a truck, SUV, ATV, UTV, or trailer. The T-handle locking system makes installation and removal quick and tool-free, while the interlocking container shapes allow stacking and mixing of capacities to tailor fuel range to any expedition.

Beyond fuel, RotopaX has expanded their lineup to include water containers, diesel packs, and truck bed storage boxes — modular, mountable storage solutions that keep trail essentials organized and secured whether you're loading up for a weekend run or a multi-week backcountry expedition. With a catalog of nearly 100 products, the RotopaX system is designed to grow with your build.

RotopaX containers are proudly made in the USA, tested by overlanders and off-road explorers worldwide, and backed by a commitment to regulatory compliance and exceptional build quality. Whether you drive a trail truck, a lifted SUV, a dual-sport motorcycle, or a purpose-built overland rig, RotopaX offers a solution to keep you moving forward — safely and confidently.
