Front Runner Jerry Can: Best for Overlanding Rigs

Front Runner is a brand deeply embedded in the overlanding world, and their jerry can design reflects a deep understanding of vehicle-mounted storage. These cans are specifically engineered to sit perfectly within the company’s extensive range of roof racks and slide-out trays. The integration is seamless, reducing the need for cumbersome straps or jury-rigged mounting solutions.

The build quality is excellent, with a focus on impact resistance and a leak-proof seal that holds up under the vibration of corrugated dirt roads. The integrated tap makes the dispensing process clean and efficient, preventing the common spillages associated with traditional jerry can pour spouts. It represents a refined middle ground between rugged field gear and modern convenience.

If the rig is already built out with a roof rack or a modular storage system, the Front Runner Jerry Can is the most compatible and effective solution. It streamlines the process of securing water and deploying it once at camp. It is a highly recommended upgrade for anyone looking to professionalize their vehicle’s storage capabilities.

Choosing Your Jug: Capacity, Material, and Spout

When evaluating water jugs, start by calculating consumption. A general rule of thumb is to carry at least one gallon of water per person, per day, for drinking, hygiene, and light cleaning. For remote trips, always add a 20% buffer for emergencies, especially if traveling in arid, high-temperature terrain.

Material matters more than most realize. High-density polyethylene (HDPE) is the industry standard for food-grade safety and durability. Ensure every container is clearly marked as BPA-free to prevent plasticizers from leaching into the water, particularly if the containers will sit in a hot vehicle.

The spout is the most common failure point. Some jugs feature simple screw-on caps, while others offer integrated taps or specialized pour spouts. For desert or hot-weather travel, a closed, leak-proof system is mandatory. Test the spout mechanism before departure; if it is prone to dribbling, the amount of wasted water can add up quickly over a long weekend.

How to Secure Water Jugs Safely in Your Rig

Water is heavy—one gallon weighs approximately 8.3 pounds. Carrying 10 gallons of water means 83 pounds of weight that must be secured against the forces of acceleration, braking, and rough terrain. Never rely on simple bungee cords; they stretch and lose tension, creating a dangerous projectile during a sudden stop.

Utilize dedicated mounting brackets or heavy-duty ratchet straps attached to solid anchor points on the vehicle chassis or frame. If the jugs are mounted on the exterior, ensure the rack system is rated for the total weight of the water. Periodically check the mounting hardware, as off-road vibration can loosen bolts over time.

Distribute weight effectively. If possible, mount water containers as low as possible to keep the center of gravity stable. For vehicles with high centers of gravity, like tall overland rigs, balancing the water weight between the left and right sides of the vehicle is essential for handling on uneven trails.

Keeping Your Water Clean: Sanitation and Storage

Even the most expensive water jug can become a health hazard if not maintained. Before the first trip of the season, sanitize the interior with a mild solution of bleach and water, then rinse thoroughly. After every excursion, empty the remaining water, allow the container to air dry completely, and store it with the lid loosely attached to prevent mold growth.

Avoid exposing clear or semi-translucent jugs to direct sunlight for long periods, as UV radiation promotes algae growth. If storage space allows, keep containers in the shade or cover them with an opaque tarp. Consistent temperature management also prevents the water from taking on a plasticky taste, which often happens when the container gets excessively hot.

Finally, keep a dedicated hose or funnel for filling the containers to ensure the water source stays clean. If using a secondary pump or hose, keep the ends capped or stored in a clean bag when not in use. Small habits like these protect the water supply from external contaminants and ensure every sip is refreshing.

Beyond the Jug: Water Filtration on the Trail

Relying solely on carried water limits the range of an expedition. Integrating a high-quality water filter allows for the replenishment of supply from natural sources like streams, lakes, or wells. A portable gravity filter or a pump-style ceramic filter provides an essential safety net when consumption exceeds the capacity of the primary storage.

Understand the difference between filtering and purification. While standard filters remove bacteria and protozoa, they often do not eliminate viruses or chemical contaminants found in stagnant water. If traveling in regions with questionable water quality, consider pairing a filter with a chemical treatment or a UV purifier to cover all bases.

Always treat water as a precious resource, but don’t be afraid to utilize the environment to extend the journey. A well-rounded water strategy combines rugged storage jugs with versatile, reliable filtration gear. This dual approach provides the freedom to stay on the trail longer and reach destinations that aren’t marked on a map.

Selecting the right water storage is a foundational step in mastering the art of off-grid travel. By balancing capacity, durability, and ease of use, you can ensure that your hydration system supports your adventures rather than hindering them. Equip your rig with gear that fits your style, maintain it with care, and keep exploring the trails with confidence.
