RotopaX RX-1G-1W 1-Gallon Gasoline/Water Pack - Red/White, Stackable Low-Profile Leakproof

RotopaX RX-1G-1W is a compact, stackable 1-gallon container system offering separate gasoline and water packs with a low-profile, leakproof design for off-road and overland use.

Designed for riders, campers, and vehicle-builders who need a small, secure reserve of fuel or fresh water, the RX-1G-1W pairs durable construction with a space-conscious shape that mounts easily to aftermarket bases. Both the gasoline and water versions share the same thin, rectangular footprint so they fit on roof racks, bed racks, spare tires, and UTV roll cages without eating precious cargo room. The pack’s three-layer rotational molding and reliable sealing make it suitable for rugged terrain, while modular compatibility lets you bolt multiple packs together for a tidy, expandable solution.

How does this pack prevent leaks during rough rides?

The RX-1G-1W uses seamless rotational molding and a precision sealing system to guard against spills and seepage even when subjected to vibration and impacts. Its twist-and-lock interface secures the container to a dedicated base so it won’t shift under load.

• Seamless three-layer construction resists cracks and punctures.
• Engineered gasket and threaded cap minimize evaporation and drips.
• Twist-lock base attachment stops movement and reduces stress on fittings.

Will the dimensions fit on my vehicle or gear mount?

With compact dimensions (13.5" H x 9.5" W x 3" D) the RX-1G-1W is deliberately slim to maximize mounting options. Its flat rectangular profile fits in narrow spaces where traditional jerry cans won’t, and it’s compatible with RotopaX mounting hardware (mount sold separately).

• Thin, rectangular shape for tight clearance areas.
• Works on roof racks, bed racks, tailgates, spare-tire carriers, and UTV roll cages.
• Mounting system lets you stack and bolt multiple packs securely.

Is this safe and legal for carrying fuel and drinking water?

RotopaX manufactures these packs in the USA and designs the gasoline version to meet EPA and CARB standards where applicable. The water pack is made from materials suitable for potable water storage when cleaned and used according to guidance.

• Gasoline container meets EPA & CARB requirements.
• Water pack constructed from water-compatible material—flush and sanitize before first use.
• Labeling differentiates fuel and water packs to avoid cross-contamination.

How do I expand capacity or organize multiple fluids on a trip?

The modular system is built to grow: bolt packs together on a single base or use several bases to secure stacks of containers for different liquids. Quick-release and twist-lock mounting makes it simple to swap packs between vehicles or storage locations.

• Stackable design allows multiple packs to be joined into one secure unit.
• Mix and match gasoline and water packs to carry both fluids safely.
• Mounting hardware sold separately for flexible installation layouts.

Who is this for: the RX-1G-1W is ideal for overlanders, weekend campers, off-road riders, ATV/UTV owners, and anyone who needs a small reserve of fuel or potable water without sacrificing cargo space. It suits DIY vehicle builders and professional trail crews who want reliable, modular containers that are easy to mount, swap, and store.
