7 Best Water Container Mounts For Long Overland Trips

Running out of water halfway through a remote desert traverse is a situation every overlander aims to avoid through careful planning and reliable gear. Securing heavy liquid reserves requires more than a few bungee cords; it demands hardware that can withstand washboard roads, technical climbs, and years of vibration. Selecting the right mount is the difference between reaching camp with supplies intact and dealing with a cracked container or a loose load on the trail.

Rotopax DLX Pack Mount: The Gold Standard Mount

The Rotopax DLX system has earned its reputation through sheer durability and modularity, making it the benchmark for serious adventure rigs. These mounts use a CNC-machined aluminum handle with a locking mechanism that provides incredible tension to prevent your containers from rattling loose. It is the ideal choice for those who prioritize security and want a standardized system that works across multiple container sizes.

Because these mounts require a single hole for mounting, they are incredibly versatile for custom installations on truck beds, rack side panels, or even bumper plates. While they represent a higher initial investment, the peace of mind they offer on long, high-speed corrugated roads is well worth the cost. If the goal is a “set it and forget it” solution, this is the gold standard.

Front Runner Jerry Can Holder: For Roof Racks

If your rig is equipped with a flat rack system, the Front Runner Jerry Can Holder is likely the most efficient way to maximize your footprint. This cage-style holder is specifically designed to accommodate standard 20-liter jerry cans, securing them with a heavy-duty ratchet strap. It keeps the container upright and contained, which is crucial for preventing fatigue on the plastic or metal seams during long-haul trips.

The major advantage here is its integration with the T-slot channels common on modern roof racks, allowing for quick adjustments or removals. However, keep in mind that mounting heavy water containers on the roof raises the vehicle’s center of gravity. This holder is perfect for travelers who need to carry large volumes of water but prefer a dedicated, low-profile footprint on their roof rack.

Wavian Heavy-Duty Holder: For Classic Jerry Cans

The Wavian holder is designed for purists who trust the robust, time-tested architecture of steel NATO-style jerry cans. This mount features a heavy-gauge steel cradle that perfectly conforms to the shape of a traditional can, ensuring zero shifting during technical maneuvers. It is built to withstand extreme mechanical abuse, making it the go-to for remote, unsupported expeditions where gear failure is not an option.

Unlike modular plastic systems, this holder is purpose-built for the specific dimensions of Wavian-style cans. The locking mechanism is simple, reliable, and practically immune to the dust and grit that can jam more complex hardware. If you are building a rugged, “old-school” overland rig and value structural steel over lightweight plastic, this is the only logical choice.

Expedition Essentials QWBM: For Truck Bed Rails

The Quick Water Bottle Mount (QWBM) from Expedition Essentials is a specialized solution for those who use bed rails, like the Toyota Tacoma deck rail system. By utilizing the existing mounting points in the truck bed, this system keeps the weight of your water supply low and centered. This is the optimal placement for handling, as it keeps the heavy liquid mass inside the wheelbase rather than hanging off a rear swing-out or sitting on a roof rack.

This mount is exceptionally sleek and doesn’t interfere with tonneau covers or rack systems mounted above the bed. It allows for quick retrieval of water containers without needing to climb onto the vehicle or reach over a high tailgate. For overlanders with limited roof space or those concerned with off-road stability, the QWBM is an elite, well-engineered solution.

Prinsu Rotopax Mount: A Low-Profile Rack Solution

The Prinsu Rotopax mount is tailored specifically for owners of Prinsu roof racks, integrating seamlessly with the existing crossbar design. By bolting directly to the rack, it maintains a extremely low profile that reduces wind noise and minimizes drag compared to bulky cages. It is a clean, aesthetic, and functional choice for those who have already invested in a specific roof rack ecosystem.

This mount is best suited for shorter trips or moderate terrain where you don’t need a massive, multi-can array. Because of its minimalist nature, it is not designed for heavy-duty, high-impact off-roading with massive containers. If you value clean lines and effective weight distribution on a dedicated roof platform, the Prinsu mount is difficult to beat.

Smittybilt I-Rack II: Versatile and Budget-Friendly

The Smittybilt I-Rack II is an excellent entry point for those who need a versatile mounting platform without the boutique price tag. It is essentially a heavy-duty rack designed to bolt onto a spare tire, which is a brilliant way to utilize dead space on the rear of a vehicle. This makes it a great choice for rigs that lack the rack systems required for the more specialized mounts listed above.

The adjustability of the I-Rack II allows it to accommodate various container shapes, including gas cans and water jugs. It is not quite as “refined” as a CNC-machined Rotopax mount, but for the price, it provides a massive jump in utility. This rack is the ideal choice for the budget-conscious traveler who wants to expand their water-carrying capacity quickly.

WaterPORT GoSpout Mount: For Pressurized Systems

The WaterPORT mount is a unique beast, specifically engineered for pressurized water tanks rather than passive storage containers. It is designed to withstand the weight of a full, pressurized tank while providing a quick-release mechanism for when you need to take the unit down to wash dishes or rinse off gear. The mount feels sturdy and incorporates a locking pin system to prevent theft or accidental detachment.

If your overland setup includes a shower or wash station, this mount is a non-negotiable upgrade over straps or bungees. It ensures the tank remains in the correct orientation for the internal pump to function properly. While it is less versatile than a standard container mount, it is perfectly optimized for the WaterPORT ecosystem.

How to Choose the Right Mount for Your Rig & Trip

Selecting a mount requires a clear understanding of your vehicle’s current configuration and the specific demands of your destination. You must first audit your available mounting points—do you have a roof rack with T-slots, a truck bed rail system, or just a spare tire? Never compromise your center of gravity by overloading a high roof rack if your rig is already prone to body roll on technical trails.

• For short weekend trips: A roof-mounted container or spare-tire rack is usually sufficient.
• For long-distance, high-speed gravel travel: Prioritize internal or bed-rail mounts to prevent vibration-induced fatigue.
• For extreme, rocky terrain: Keep water inside the wheelbase or on a frame-mounted swing-out to minimize the impact of articulation on your containers.

Always consider the “empty weight” of the mounting hardware itself. Adding ten pounds of steel to carry a five-pound water container is counterproductive. Match the durability of the mount to the intensity of the road ahead; a simple strap system might work for fire roads, but it will fail on a multi-day washboard slog.

Mounting Securely: Installation and Safety Checks

Proper installation is just as important as the quality of the mount itself. Always use thread-locking compound on bolts that are subject to constant vehicle vibration, as these can easily back out over hundreds of miles. Regularly inspect the hardware at every fuel stop, especially during the first few days of a long trip when the gear is “settling” into its mount.

Pay close attention to the tension of your mounting interface; if a container can wiggle or shift even a few millimeters, it will eventually rub through plastic or fatigue metal. Never place plastic containers in direct contact with sharp-edged metal mounts without a protective rubber shim or gasket. A few minutes spent adding padding before you leave home will prevent a catastrophic leak miles from civilization.

Water Containers and On-the-Road Filtration Tips

While the mount secures the container, the quality of the water inside is your responsibility. Always use food-grade, BPA-free containers to prevent plastic leaching, especially when the vehicle is parked in high-heat desert environments. Periodically sanitize your containers with a diluted bleach solution, even if you are using a filtration system, to prevent biofilm buildup.

If you are filling up from natural water sources, a secondary filtration step is essential. Carry a gravity-fed or pump filter that can handle the volume of your containers, as “potable” water sources in remote areas can be deceiving. Remember that a mount is only as good as the container it holds—keep your containers clean, shielded from direct UV exposure when possible, and consistently maintained.

The right water mount is the quiet hero of a successful overland trip, ensuring your most essential resource remains secure through every mile. Choose your hardware based on your vehicle’s specific layout, commit to a rigorous inspection schedule, and stay focused on the horizon. Preparation ensures that once you reach that perfect, remote campsite, you have the peace of mind to enjoy it fully.
