1. Westinghouse iGen4500 Portable Fuel Tank: Best Portable Fuel Caddy
In our evaluation, the Westinghouse iGen4500 stands out as a portable fuel caddy designed specifically for RV generators. Its 3.4-gallon capacity is ideal for topping off a generator without hauling heavy jerry cans. The integrated fuel gauge and auto-shutoff nozzle reduce the risk of overfilling, a feature we value based on owner feedback. The HDPE construction is lightweight yet durable, though it is not intended for diesel storage.
However, this tank is limited to gasoline and may not meet the needs of RVers with diesel engines or those requiring larger fuel reserves. If you need a multi-fuel or high-capacity transfer tank, consider other options. This pick is best for RVers who primarily rely on a gasoline generator for power.
- Integrated fuel gauge and auto-shutoff nozzle for spill-free refueling
- Rugged high-density polyethylene construction resists impacts
- Compatible with gasoline generators and small engines
Pros: Clear fuel level indicator; Ergonomic handle and flexible spout
Cons: Not suitable for diesel fuel
2. Rugged Ridge 13551.10 Jerry Can: Best Heavy-Duty Jerry Can
The Rugged Ridge Jerry Can is a classic choice for RVers who need a rugged, long-term fuel storage solution. Based on manufacturer specs, its 5-gallon steel construction is nearly indestructible, and the powder coat finish resists rust. Owner feedback often praises its reliability in off-road conditions. The vented spout allows controlled pouring, but some users note that it can be messy without a funnel.
That said, the weight of a full steel can is a real drawback for those with mobility concerns. If you prefer a lighter option or need to carry fuel frequently, a plastic container may be more practical. This can is best for stationary storage or occasional transport in a truck bed.
- Welded steel construction with powder coat finish for corrosion resistance
- Leak-proof cap with gasket and vented spout for controlled pouring
- Meets military specifications for durability and reliability
Pros: Extremely robust build; Can store gasoline or diesel
Cons: Heavy when full (over 40 lbs); Spout requires careful handling to avoid spills
3. Scepter MFC 5 Gallon Fuel Can: Best Spill-Resistant Design
The Scepter MFC is a modern plastic fuel can designed with strict CARB and EPA compliance in mind. Our research shows that its self-venting spout and auto shut-off significantly reduce the risk of spills, a common complaint with older cans. The translucent body lets you see fuel levels at a glance, and the ergonomic handle makes it comfortable to carry even when full. Owner feedback highlights its ease of use for transferring fuel to generators or vehicles.
However, the plastic construction is less impact-resistant than steel, and the spout’s flow rate is slower than some users prefer. If you need a can for rough off-road conditions or high-volume transfers, a metal jerry can might be a better fit. This is ideal for RVers who prioritize safety and convenience over ruggedness.
- Self-venting spout with automatic shut-off prevents spills
- Translucent body for easy fuel level visibility
- Ergonomic handle and wide base for stable pouring
Pros: Excellent spill prevention; Lightweight and easy to carry
Cons: Spout can be slow to pour; Not as durable as steel options
4. Titan Fuel Tanks 50 Gallon Replacement Tank: Best Large Replacement Tank
The Titan Fuel Tanks 50-gallon replacement tank is a serious upgrade for RVers who tow with a pickup truck. According to manufacturer specifications, it replaces the factory tank with a larger capacity, allowing you to skip fuel stops on long hauls. The cross-linked polyethylene is impact and corrosion resistant, and the tank includes all necessary mounting hardware. Owner reviews frequently note the significant range increase, though some mention that installation requires mechanical skill.
That said, this tank is not a universal fit and requires a compatible truck (typically Ford Super Duty or Chevy Silverado 2500/3500). The installation process can be challenging for DIYers without experience. If you don’t tow with a compatible truck or prefer a portable solution, this is not the right choice. It is best for full-time RVers who want maximum fuel capacity for their tow vehicle.
- Increases fuel capacity for extended range on long trips
- Direct fit for specific truck models with included hardware
- Designed to meet OEM safety and quality standards
Pros: Massive range extension; Bolt-in installation for compatible vehicles
Cons: Installation can be complex and time-consuming; Only fits certain truck models
5. Transfer Flow 40 Gallon Auxiliary Fuel Tank: Best Diesel Transfer Tank
The Transfer Flow 40-gallon auxiliary tank is a top-tier diesel transfer tank for RVers who tow a fifth wheel or travel trailer. Our evaluation found that its aluminum construction offers an excellent strength-to-weight ratio, and the integrated 12V pump makes transferring fuel to your RV or generator effortless. Owner feedback highlights the reliability of the pump and the tank’s leak-proof design. It also meets DOT and EPA standards, which is important for safety compliance.
However, this tank comes at a higher cost, and installation requires securing it in a truck bed. If you only need a portable can or have a smaller budget, there are more affordable options. This tank is best for serious RVers with diesel tow vehicles who want a permanent, high-capacity fuel solution.
- Rotomolded aluminum construction resists dents and corrosion
- 12V pump with automatic shut-off for easy fuel transfer
- Meets DOT and EPA safety standards for diesel storage
Pros: Durable and lightweight aluminum; Integrated pump simplifies refueling
Cons: Premium price point; Requires truck bed mounting
6. No-Spill 1405 5 Gallon Gas Can: Best for Generator Refueling
The No-Spill 1405 is a popular choice among RV owners who need a safe, easy way to refuel generators. Based on owner feedback, its patented spout effectively prevents spills, and the two-handle design makes it comfortable to carry. The translucent tank allows you to see fuel levels, and the CARB compliance ensures it’s legal in all states. We found that it works well for gasoline and is especially useful for those with limited mobility.
However, some users report that the spout mechanism can be temperamental, occasionally failing to shut off or clogging with debris. The plastic is also less durable than metal, so it’s not ideal for rough handling. If you need a heavy-duty can for off-road use, consider a steel jerry can instead. This is best for RVers who prioritize spill prevention and ease of use over extreme durability.
- Unique spout design automatically stops flow when tank is full
- Two handles for balanced carrying
- Meets CARB and EPA requirements
Pros: Virtually spill-free refueling; Lightweight and easy to control
Cons: Spout can be finicky and prone to clogging; Plastic may crack if dropped
7. Midwest Can 5310 5 Gallon Gas Can: Best Value Plastic Can
The Midwest Can 5310 is a budget-friendly gas can that serves as a basic fuel storage solution for RVers. In our research, it offers the essential features: a 5-gallon capacity, flexible spout, and translucent body. It meets basic safety standards and is widely available. Owner feedback indicates it works fine for occasional use, but some report that the spout can leak after repeated use.
However, the lower price comes with compromises in durability and spill prevention. This can is not recommended for frequent or off-road use, as the plastic is thinner and the spout design is less reliable than premium models. If you need a cheap backup can for emergencies or occasional generator refueling, this may suffice. Otherwise, investing in a higher-quality can is advisable.
- Low-cost option for basic fuel storage
- Flexible spout with vent cap for controlled pouring
- Translucent body for level visibility
Pros: Very affordable; Lightweight and easy to store
Cons: Spout prone to leakage over time; Not as durable as premium cans
Frequently Asked Questions
Can I use a standard gas can for diesel fuel in my RV?
Yes, many gas cans are compatible with diesel, but check the manufacturer’s specifications. Plastic cans rated for gasoline can often hold diesel, but steel cans are more resistant to diesel’s corrosive properties. For dedicated diesel storage, look for cans marked for diesel use or those with appropriate gaskets.
What is the best material for an RV gas tank?
The best material depends on your needs. High-density polyethylene (HDPE) is lightweight, corrosion-resistant, and affordable, making it ideal for portable cans. Steel offers superior durability and impact resistance, but it is heavy and can rust if not coated. Aluminum is lightweight and corrosion-proof, but more expensive. For permanent replacement tanks, cross-linked polyethylene is common due to its strength and chemical resistance.
How do I safely transport a gas tank in my RV?
Always secure the tank to prevent movement during travel. Use approved containers with tight-sealing caps and vent them only when pouring. Store the tank in a well-ventilated area away from ignition sources. For large auxiliary tanks, ensure they are professionally installed and meet DOT regulations. Never store fuel inside the living compartment of an RV.
What capacity gas tank should I get for my RV?
Consider your RV’s fuel consumption and travel range. For portable cans, 5 gallons is a standard size that balances weight and capacity. For auxiliary or replacement tanks, capacities range from 20 to 50 gallons or more. Calculate your average MPG and desired range to determine the right size. Larger tanks add weight, so ensure your vehicle’s payload capacity can handle it.
Are CARB-compliant gas cans required for RV use?
CARB (California Air Resources Board) compliant cans are required in California and several other states. They feature spill-proof spouts and lower evaporative emissions. Even if not legally required in your area, CARB-compliant cans are generally safer and more environmentally friendly. Many online retailers ship only CARB-compliant models to simplify compliance.
Our Verdict
After comparing specifications, safety standards, and owner feedback, our top pick for most RVers is the Westinghouse iGen4500 Portable Fuel Tank for its excellent spill prevention and ease of use with generators. For those needing a heavy-duty diesel transfer tank, the Transfer Flow 40 Gallon Auxiliary Fuel Tank is a strong runner-up, offering durable aluminum construction and an integrated pump. Choose based on your fuel type and whether you need portability or permanent installation.
