It is designed specifically to integrate with the Front Runner Slimline II rack system, though it can be adapted elsewhere.

This mount is intended for the serious traveler who carries redundant fuel for multiple vehicles or long-haul solo desert treks. While it adds significant weight to the roof, its rugged construction offers the security needed for high-speed desert crossings. Select this mount if you need a bombproof, high-capacity system that integrates seamlessly into a comprehensive modular rack setup.

Wavian Front Loading Steel Jerry Can Mount

For those who rely on classic steel NATO-style jerry cans, the Wavian front-loading mount is a masterpiece of utilitarian design. It allows for quick retrieval of the fuel can without the need to lift it vertically, which is a significant ergonomic advantage when dealing with 40-pound loads. The inclusion of a latch that accommodates a padlock adds a necessary layer of security when parked in public areas.

This hardware is engineered for the traditionalist who values the durability of steel over modern plastics. It is arguably the most robust option for extreme environments where containers may encounter rocks or heavy brush. If you already trust your fuel storage to classic steel cans, this mount is the most efficient and secure way to carry them.

Smittybilt 2798 Jerry Can Mounting Bracket

The Smittybilt 2798 is a straightforward, budget-conscious solution that does exactly what it promises without unnecessary complexity. It features a universal design that bolts to almost any flat surface, making it an excellent choice for those who are building out a custom rack or trailer. While it lacks the fancy latches of more expensive models, its heavy-duty construction remains reliable under load.

This mount is ideal for the DIY overlander who prefers simple, mechanical solutions that are easy to field-repair. It serves as a great entry-level option for those who aren’t ready to invest in premium, vehicle-specific rack accessories. If you need a reliable, no-nonsense bracket that fits into a wide variety of custom builds, this is an excellent utility choice.

ARB Horizontal Jerry Can Holder for Roof Racks

ARB has designed this horizontal mount to alleviate the struggle of lifting heavy fuel cans to roof height. By lying the can flat, the weight is distributed more evenly across the rack’s load bars, which helps maintain a better center of gravity for the vehicle. The powder-coated finish matches the rugged aesthetic of the iconic ARB rack systems perfectly.

This horizontal configuration is a smart choice for vehicles with tall rooflines where vertical clearance is a concern or where reaching high is physically difficult. It reduces the risk of spilling during fueling and keeps the rack profile relatively low. Opt for this mount if your vehicle setup prioritizes roof-mounted fuel but requires a more stable, lower-center-of-gravity approach.

Rhino-Rack Vertical Jerry Can Holder Mount

Rhino-Rack delivers a sturdy, vertical solution that is designed to maximize limited rack real estate. The mount is engineered for rapid accessibility, allowing for quick deployment of fuel containers during long trail days. It features a robust clamping mechanism that keeps the can rigid, effectively preventing the “sloshing” that can destabilize a vehicle on technical terrain.

This is the right choice for the adventurer who needs to keep rack space free for other gear like recovery boards or spare tires. It is particularly effective for mounting on side rails, which keeps the heavy fuel weight off the very top of the vehicle. If you need to keep your gear footprint small while maintaining quick access to your reserves, this vertical mount is the right tool.

How to Choose the Right Fuel Mounting System

Selecting the proper mount starts with assessing the total weight you intend to carry versus your vehicle’s roof load rating. Steel cans are heavier than plastic, and every pound placed on the roof affects your vehicle’s handling and body roll. Consider the frequency of use: if you only need extra fuel once a year, a simple, permanent mount is fine, but for constant use, prioritize speed of access.

Compatibility with your existing rack platform is the next hurdle. Many manufacturers create “ecosystem” mounts that only fit their specific brands of roof racks or bed bars. Always verify if the hardware requires proprietary channels or if it provides a universal flat-plate mounting solution before making a purchase.

Essential Tips for Safe Fuel Tank Mounting

Always ensure your fuel containers are fully secured, and check the latch tension every time you stop to refuel or inspect your gear. A loose jerry can vibrating against a metal mount will eventually lead to material fatigue or a catastrophic breach. Use locking cables or padlocks on all mounts to deter theft, as unsecured fuel cans are high-value targets in remote areas.

Never mount fuel tanks in a position where they can be impacted by rocks or tree limbs on tight trails. If you are mounting on the exterior, ensure the spout is pointed away from the vehicle body to prevent potential leaks from compromising your paint or wiring. Most importantly, always leave a small amount of headspace in the fuel container for thermal expansion, as fuel volume fluctuates significantly with heat.

Balancing Vehicle Weight With Extra Fuel Tanks

Carrying extra fuel dramatically alters the center of gravity, making your vehicle more prone to swaying in tight corners or off-camber sections. Whenever possible, mount your fuel as low as possible on the vehicle, such as in a bed rack or a swing-away rear bumper carrier. Keeping the weight between the axles is always superior to placing it over the roof or at the extreme rear of the vehicle.

If roof mounting is the only option, compensate by reducing the load of other items in the vehicle to keep your total gross vehicle weight rating (GVWR) within manufacturer specs. Be mindful that an extra 50 pounds of fuel on the roof is amplified by every bump and turn you take. Adjust your driving speed and increase following distances to account for the increased stopping distance and top-heavy handling.

Maintaining Your Hardware on Rough Terrain

The vibration of high-speed gravel roads is the fastest way to loosen mounting hardware. Implement a routine of checking all bolts, nuts, and straps at every fuel stop or campsite arrival. Look specifically for signs of stress fractures in the brackets or thinning of the metal where the container contacts the frame.

Apply a light coat of anti-seize to bolts and periodically clean the latch mechanisms to ensure they operate smoothly in dusty or sandy environments. If you notice signs of corrosion, sand the area and apply a touch-up paint immediately to prevent deep rust. A well-maintained mount lasts the life of the vehicle, whereas a neglected one will eventually fail at the worst possible moment in the deep woods.

Equipping your vehicle with a reliable fuel mounting system is a foundational step toward true off-grid independence. By selecting hardware that matches your specific storage needs and respecting the physics of a loaded vehicle, you set yourself up for many successful miles of exploration. Keep your gear maintained, stay mindful of your weight distribution, and focus your energy on the next horizon.
