RotopaX storage packs hold gasoline, water, diesel, kerosene and more and when Jeepers are out on the trail in places like Moab and Johnson Valley, they come in handy. Lose the bulk of a hulking cargo box and be prepared for your next adventure with one of their storage packs. RotopaX's patented 3-layer roto-molding process combines with a specially formulated plastic barrier material to keep contents sealed, stable and secure. All of the company's packs are 100% made in America and in addition, RotopaX carries mounting hardware, spouts and accessories and packs for emergency preparedness. Some of their packs are interlocking as well, to keep you efficiently equipped to the gills and stretch your off-roadability to the paX.
