RotopaX 2 Gallon Gasoline Gen 2

The RotopaX 2 Gallon Gasoline Gen 2 is a roto-molded HDPE fuel pack that holds 2.0 US gallons in a flat case roughly 17.75 x 13.25 x 3 inches. The 3-inch profile is the whole point: it lies flush against a flat-panel mount on a bed rail, tailgate, roof rack, or UTV cage instead of eating cargo room like a round jerry can. The pack is EPA and CARB compliant, carries a Flame Mitigation Device, and seals with a gasketed cap, so it ships and stores leak-proof in all 50 states.

Gen 2 is the simplified version of RotopaX's original 2-gallon. The original molded a twist-lock into the bottom so two packs could interlock into a single 4-gallon block. Gen 2 drops that feature for a flat bottom, which lowers the price while keeping the same capacity and external footprint. It still stacks with other RotopaX packs using an extension mount, and it ships with the upgraded spout-and-cap assembly for cleaner pours.

One thing to plan for: the mount is sold separately. The pack and spout are in the box; a RotopaX Pack Mount (Standard, DLX, or LOX) holds it to the rig. Any RotopaX mount fits any RotopaX pack size, so a single mount style runs your whole fuel-and-water row.
