1. Norwesco 25 Gallon Pickup Truck Bed Water Tank: Top Pick: Versatile & Durable
In our evaluation, the Norwesco 25 Gallon Pickup Truck Bed Water Tank stands out for its robust construction and thoughtful design.

2. RDS 40 Gallon Aluminum Wheel Well Tank: Best for Space Optimization
The RDS 40 Gallon Aluminum Wheel Well Tank is a top performer for truck owners prioritizing bed space. Its unique design allows it to sit snugly over the rear wheel well, leaving the main bed area open for other cargo. Based on owner feedback and the spec sheets, the heavy-duty aluminum construction is highly regarded for its durability and resistance to corrosion, crucial for tanks exposed to various elements and liquids.
A notable consideration for this tank is its aluminum construction. While exceptionally durable, aluminum tanks can be more susceptible to denting from impacts compared to flexible polyethylene if not properly protected.

For applications demanding a substantial water supply, the Tuff-Tank 50 Gallon Rectangular Polyethylene Tank presents a compelling option. Our research into its construction materials confirms its resilience, utilizing rotationally molded linear low-density polyethylene known for its superior impact strength and resistance to environmental stressors. Owner feedback frequently highlights its reliability for tasks like watering livestock or supplying remote work sites.
The primary limitation of this 50-gallon tank is its sheer size and weight when filled. A full tank weighs over 400 pounds, which significantly impacts a truck’s payload capacity and potentially its handling dynamics. This makes it less suitable for smaller trucks or users who frequently need to carry other heavy cargo. Those who require maximum bed flexibility or have payload constraints should opt for smaller capacity tanks or wheel well designs.
- Manufactured from durable linear low-density polyethylene
- Large 50-gallon volume for extended water supply

Pros: Excellent for heavy-duty agricultural or industrial use; Resistant to most chemicals and impacts; Relatively straightforward to secure with proper straps
Cons: Significant footprint occupies substantial bed space; Weight when full requires careful consideration for truck payload
4. Dura-Tote 15 Gallon Portable Water Tank: Portable & Convenient
The Dura-Tote 15 Gallon Portable Water Tank is designed for versatility and ease of use, making it an attractive option for those who need a flexible water solution. Its compact footprint and integrated handle make it simple to load, unload, and position within a truck bed or even outside the vehicle. Based on owner feedback, its food-grade material is appreciated for ensuring the safety of potable water, a critical factor for personal consumption.
However, the smaller 15-gallon capacity, while contributing to its portability, means it may not be sufficient for extended trips or demanding applications like large-scale cleaning or long-term remote hydration. Furthermore, while it’s easy to place, it lacks the secure, integrated mounting points of more permanent truck bed tanks, requiring users to rely on external straps or tie-downs for safe transport. For users needing a truly fixed and high-capacity water source, this portable option will fall short.
- Compact design for easy transport and storage
- Made from food-grade polyethylene material
- Features a large fill cap and a smaller drain port
Pros: Highly portable, can be easily moved in and out of the truck; Good for camping, tailgating, or small-scale water needs; Integrated handle enhances ease of carrying
Cons: Smaller capacity limits use for larger tasks; Less robust mounting options compared to dedicated truck tanks
5. Icon Direct 30 Gallon RV Fresh Water Tank: RV-Ready Option
The Icon Direct 30 Gallon RV Fresh Water Tank, while primarily marketed for RV installations, can be adapted for pickup truck use, offering a decent mid-range capacity. Our evaluation of its construction indicates a robust, impact-resistant plastic that is suitable for fresh water storage. The inclusion of multiple ports is a notable advantage, providing flexibility for custom plumbing setups, which is appreciated by those with specific water delivery needs.
A significant drawback for truck owners is that this tank is not purpose-built for truck beds. It lacks integrated baffles, which means water sloshing can be pronounced during transit, potentially affecting vehicle stability. Additionally, it requires custom fabrication for secure mounting and plumbing adapted for truck use, adding complexity and cost. Truck owners seeking a plug-and-play solution or one specifically designed to manage dynamic loads should look at dedicated truck bed tanks with internal baffling.
- Designed for fresh water storage in RVs and similar applications
- Constructed from durable, impact-resistant plastic
- Multiple ports for inlet, outlet, and vent connections
Pros: Good mid-range capacity for various uses; Versatile port locations for custom plumbing; Relatively lightweight for its capacity
Cons: Requires custom mounting and plumbing for truck bed use; Shape may not optimize truck bed space as effectively as others
6. Reliance Products Aqua-Tainer 7 Gallon Rigid Water Container: Basic & Budget-Friendly
The Reliance Products Aqua-Tainer 7 Gallon Rigid Water Container is an entry-level option primarily suited for casual use, such as camping or short trips. Its lightweight design, hideaway handle, and integrated spigot contribute to its convenience, making it easy to handle and dispense water. Based on aggregated owner feedback, its affordability and basic functionality are its main strengths for those with minimal water requirements.
However, the durability of this container, while acceptable for light use, is not on par with the heavy-duty polyethylene or aluminum tanks designed for rigorous truck bed environments. It is more susceptible to damage from impacts or prolonged exposure to harsh conditions. Furthermore, its small 7-gallon capacity is quickly depleted for most truck-related tasks, making it inadequate for agricultural, construction, or extended outdoor adventures. Users who need a robust, high-capacity, or semi-permanent water solution for their truck will find this option insufficient and should invest in a more specialized tank.
- Collapsible spigot and hideaway handle for portability
- Made from rigid, BPA-free plastic
- Translucent design allows for easy water level monitoring
Pros: Very portable and easy to store when empty; Spigot provides convenient dispensing; An economical choice for basic water transport
Cons: Limited capacity for serious truck applications; Durability is lower compared to heavy-duty tanks
7. Scepter 5 Gallon Water Container: Ultra-Compact Emergency Use

Frequently Asked Questions
What material is best for a pickup truck water tank?
Based on our research, the most common and effective materials are high-density polyethylene (HDPE) and aluminum. HDPE is valued for its impact resistance, flexibility, and chemical inertness, making it suitable for potable water. Aluminum tanks are known for their strength, lighter weight relative to steel, and corrosion resistance, often preferred for their structural integrity and space-saving designs like wheel well tanks.
How do I secure a water tank in my truck bed?
Properly securing a water tank is critical for safety. We recommend using heavy-duty ratchet straps that can be anchored to your truck’s tie-down points. Some tanks may come with integrated mounting flanges or a frame that can be bolted directly to the truck bed. For larger tanks, especially those without baffles, consider adding additional support to prevent shifting during sudden stops or turns, adhering to manufacturer guidelines and local transportation safety standards.
What capacity water tank do I need for my truck?
The ideal capacity depends on your intended use. For short camping trips or emergency water, a 7-15 gallon portable tank might suffice. For agricultural, construction, or extended off-grid use, a 25-50 gallon tank or larger is often necessary. We advise considering the duration of your trips, the number of users, and the specific water demands (e.g., drinking, washing, equipment cleaning) to determine the appropriate volume, while also factoring in your truck’s payload capacity.
Can I use a regular water tank for drinking water?
Only use a water tank specifically labeled as ‘food-grade’ or ‘potable water safe’ for drinking water. These tanks are manufactured from materials that do not leach harmful chemicals into the water, meeting safety standards for human consumption. Tanks not specified as food-grade may contain plastics or coatings that are unsafe for potable water, and should only be used for non-potable purposes.
Do truck water tanks need baffles?
In our evaluation, tanks with internal baffles are highly recommended for truck bed applications. Baffles are internal structures that break up the volume of water, preventing it from sloshing violently during vehicle movement. This significantly improves vehicle stability, reduces stress on the tank and mounting points, and enhances driving safety, especially with large capacities. Tanks without baffles require more careful driving and securing.
Our Verdict
After extensive research and comparison, the Norwesco 25 Gallon Pickup Truck Bed Water Tank earns our top pick for its exceptional blend of durability, effective anti-slosh design, and versatile capacity, making it suitable for a wide range of users. As a strong runner-up, the RDS 40 Gallon Aluminum Wheel Well Tank offers superior space optimization and robust aluminum construction, ideal for those who need to maximize their truck bed cargo area.
