7 Best Portable Fuel Tanks For RV Travel That Support Self-Reliance
Go further, stay longer with these fuel tanks.
You’re deep in a national forest, miles from the nearest town, and the generator sputters to a stop. That perfect boondocking spot suddenly feels a lot more remote. This is the moment every RVer dreads, where a simple lack of fuel can turn an adventure into a logistical nightmare. Self-reliance isn’t just a mindset; it’s about having the right tools to extend your freedom and eliminate dependency on the grid.
A reliable portable fuel tank is one of the most critical pieces of gear for true off-grid travel. It’s not just about extra miles for your rig’s engine. It’s about powering your generator for days, refueling your toys like ATVs or dirt bikes, and having the peace of mind that you can stay put without worrying about your next fill-up. Choosing the right tank means balancing capacity, portability, and safety to match your specific travel style.
This isn’t about just grabbing any red can off a shelf. The best tanks are designed for the rigors of the road, preventing leaks, fumes, and spills that can ruin a trip. We’re going to break down the top options that deliver on durability and function, ensuring your fuel stays secure and ready, so you can focus on the journey, not the nearest gas station.

Boost Your Boondocking with the Best Fuel Tanks
Having extra fuel on board is the ultimate enabler for extended boondocking. It’s the difference between a three-day trip and a week-long stay in that perfect, secluded spot. The right portable fuel tank system is your lifeline, providing power for your generator, heat for your furnace, and range for your tow vehicle or motorized RV.
When selecting a tank, your primary considerations should be capacity, material, and transfer method. A five-gallon can might be perfect for running a small generator, but you’ll want a 20+ gallon caddy if you’re refueling a Class A or a thirsty truck. Look for durable materials like powder-coated steel or high-density polyethylene (HDPE) that can withstand vibrations and temperature swings without cracking or leaking.
Ultimately, the goal is a system that is both safe and easy to use. A leaky can or a cumbersome pump can create a dangerous mess far from help. The best solutions integrate secure transport, simple dispensing, and rugged construction, ensuring your fuel reserve is an asset, not a liability.
Wavian Jerry Can: The Gold Standard for Your Rig
This authentic 20-liter NATO jerry can, built from durable, rust-proof steel, ensures safe and leak-free fuel transfer with its secure spout system. EPA & CARB compliant, it's ideal for reliable fuel storage and transport.
The Wavian Jerry Can is an icon for a reason. Its design has been tested for decades in the most demanding military and overland environments. Made from 0.9mm pickled steel, these cans are built to survive impacts and abuse that would destroy lesser plastic containers.
What truly sets the Wavian apart is its leak-proof bayonet closure and locking pin. This system creates an airtight seal that prevents fumes from escaping and fuel from sloshing out, even when stored on its side or on a rough trail. The interior is lined with a rust-resistant coating, ensuring the fuel stays clean and your engine or generator remains uncontaminated.
The trade-off for this durability is weight; a full steel can is significantly heavier than its plastic counterpart. However, for those who prioritize absolute reliability and a spill-proof design, the Wavian is the undisputed champion. It’s a buy-it-for-life piece of gear that provides unmatched peace of mind.
Scepter Duramax: Roll Your Fuel with Total Ease
Easily transport and dispense fuel with the Scepter 14-Gallon Gas Caddy. This durable polyethylene container features a Flo n' Go pump to prevent spills and large wheels to navigate any terrain.
Moving large quantities of fuel can be a back-breaking task. The Scepter Duramax solves this problem with a simple, brilliant design: it puts the fuel on wheels. This 14-gallon caddy is a game-changer for RVers who need to transport significant amounts of fuel from their vehicle to a generator or the RV’s main tank.
The Duramax is more than just a container; it’s a complete fuel transfer system. It features a patented Flo n’ Go hand pump and a long hose, allowing you to refuel without lifting, tipping, or spilling. This is especially useful for filling a tall RV tank directly from the ground, eliminating the need for clumsy funnels and risky lifting.
While its large size requires dedicated storage space in a truck bed or large RV bay, the convenience it offers is immense. It transforms refueling from a dreaded chore into a quick, clean process. For those running large generators or frequently topping off their main tank, the Duramax makes managing fuel logistics incredibly simple.
Flo-Fast System: Pump Fuel Quickly and Safely
Easily transfer fluids with the Flo-Fast 30050-R System Pump. This durable red pump offers efficient fluid handling for various applications.
The Flo-Fast system is engineered for one thing: moving fuel as quickly and safely as possible. This isn’t just a can; it’s a professional-grade transfer system built around a robust, manual rotary pump. It can move up to 8 gallons per minute, making it one of the fastest manual options available.
Safety and cleanliness are at the core of the Flo-Fast design. The pump creates a sealed connection, minimizing vapor release and eliminating the risk of spills associated with traditional "tip and pour" methods. The heavy-duty, rotationally-molded polyethylene containers are incredibly durable and can be secured with optional transport systems for rock-solid stability on the road.
This system represents a significant investment compared to a standard gas can. However, for RVers who frequently transfer large volumes of fuel—for their rig, a boat, or multiple off-road toys—the speed and safety are well worth the cost. It turns a ten-minute refueling job into a two-minute task with zero mess.
Todd 28-Gallon Gas Caddy: Maximize Your Range
Easily transport and dispense up to 35 gallons of gasoline, diesel, or kerosene with this robust steel fuel caddy. Its two-way rotary pump and 8" wheels ensure efficient, effortless refueling for vehicles, lawn equipment, and boats.
When 5 or 10 extra gallons just won’t cut it, the Todd 28-Gallon Gas Caddy steps in. This is a serious fuel solution for full-timers, toy hauler owners, or anyone looking to establish a true off-grid basecamp for an extended period. Its massive capacity can nearly double the range of some RVs or run a generator for weeks.
Constructed from cross-linked polyethylene, the Todd caddy is built to marine-grade standards, meaning it’s exceptionally resistant to corrosion and impacts. It uses a simple, gravity-fed system with a 10-foot hose, allowing you to park your tow vehicle on slightly higher ground and let gravity do the work. The large, pneumatic tires make it surprisingly manageable to move across gravel or uneven terrain.
The obvious consideration here is its sheer size and weight when full. This isn’t a caddy you toss in the back of an SUV; it requires a truck bed or a dedicated storage bay. But for those who measure their boondocking trips in weeks instead of days, the Todd caddy provides an unparalleled level of fuel independence.
The No-Spill Can: Your Cleanest Fuel Transfer
Effortlessly pour fuel with the Stens 2 1/2 Gallon Fuel Can. Its thumb button control and 7/8-inch funnel spout ensure precise filling, while the integrated screen and dust cover keep your equipment clean.
Every RVer knows the frustration of a poorly designed gas can spout that spills more fuel than it pours. The No-Spill can directly addresses this with its innovative push-button control. You simply insert the nozzle into the tank, press the button to start the flow, and release it to stop instantly.
This simple mechanism provides total control, eliminating drips and overfills. The auto-stop feature on the nozzle even prevents spills once the receiving tank is full. This is fantastic for keeping your RV, your hands, and the environment clean. No more smelly fuel residue in your storage compartments.
No-Spill cans typically come in smaller sizes (1.25 to 5 gallons), making them ideal for generators, chainsaws, or topping off a small tank. They aren’t designed for refueling your entire RV, but as a clean, easy-to-use solution for your auxiliary power needs, they are second to none.
Smittybilt Jerry Can: Built Tough for Off-Grid
Securely store your jerry gas can with the Smittybilt 2798 Jerry Gas Can Holder. This durable mount ensures your fuel is safely accessible on any adventure.
For the RVer who ventures far off the beaten path, the Smittybilt Jerry Can offers a rugged, no-nonsense fuel solution. Like the Wavian, it follows the classic military design, emphasizing durability over all else. It’s constructed from heavy-gauge steel and designed to be mounted on exterior carriers, freeing up valuable interior storage space.
The Smittybilt can features a three-handle design, which makes it easier to carry and pour, especially when full and heavy. The locking cap and spout system are designed to prevent leaks and withstand the constant vibration of washboard roads and rough trails. It’s a favorite in the overlanding community for its proven toughness.
This is a purely functional piece of equipment. It lacks the convenience of a built-in pump or wheels, but it makes up for it in sheer resilience. If your RV adventures involve challenging terrain where equipment failure is not an option, the Smittybilt provides the bomb-proof reliability you need.
JohnDow Gas Caddy: Pro-Grade Fuel on the Go
The JohnDow Gas Caddy brings professional, shop-level quality to the RV world. This is a heavy-duty, industrial-grade unit made from welded steel, not plastic. It’s designed for people who treat fuel management as a critical, everyday task, not an occasional necessity.
Its standout feature is the high-quality, two-way rotary pump, which allows you to not only dispense fuel but also siphon it back out if needed. This is incredibly useful for servicing equipment or transferring fuel between vehicles. The heavy-duty wheels and sturdy handle make moving its 25-gallon capacity manageable, despite the caddy’s substantial weight.
This is overkill for the casual weekender, both in price and capability. But for the full-time RVer, the mobile mechanic, or the motorsport enthusiast hauling a trailer full of thirsty machines, the JohnDow caddy is a top-tier investment. It offers unmatched durability and professional-grade functionality for those with serious fuel demands.
Choosing the right portable fuel tank is a direct investment in your freedom. It’s about more than just carrying extra gasoline or diesel; it’s about giving yourself the option to stay longer, explore further, and handle the unexpected without derailing your plans. The perfect solution for you depends entirely on how you travel—your rig’s needs, your power consumption, and the kinds of places you want to go.
Whether you need the bomb-proof reliability of a steel jerry can or the back-saving convenience of a wheeled caddy, the goal remains the same: self-reliance. By equipping yourself with a safe and effective way to manage your fuel, you remove one of the biggest constraints of life on the road. You’re no longer tethered to the next town on the map.
So, as you plan your next adventure, think about what’s holding you back. If it’s the fear of an empty tank, you now have the tools to solve it. A good fuel tank doesn’t just hold fuel; it holds potential. The potential for one more sunset, one more day off-grid, and one more memory made far from the noise of the world.
