1. RotoPax 2-Gallon Water Pack: Best for Compact Trucks
The RotoPax 2-Gallon Water Pack is a rugged, compact water storage solution ideal for smaller trucks or those needing a portable backup. Its rotomolded HDPE construction is built to withstand drops and sun exposure, and the integrated handle makes it easy to carry. Owner feedback consistently praises its leak-proof design and secure mounting options.
However, at only 2 gallons, this tank is not suitable for extended camping trips requiring water for cooking, cleaning, or showering. It’s best for day trips or as an emergency reserve. Skip this if you need a primary water source for a family or group.
- Ultra-compact design fits in tight truck beds or under tonneau covers
- Rotomolded polyethylene is impact and UV resistant
- Integrated carry handle and mounting holes for secure tie-down
Pros: Very durable construction; Easy to mount and remove
Cons: Small capacity limits use to personal hydration, not full camp water supply
2. Front Runner 40 Liter Water Tank: Best Modular System
The Front Runner 40 Liter Water Tank is a well-engineered option for campers who already use or plan to use Front Runner’s modular roof rack or bed rack system. The tank is made from UV-stabilized polyethylene and includes a brass outlet for easy hose connection. Owner feedback highlights its robust construction and leak-free performance over years of use.
However, the tank requires the proprietary mounting system for best fit, which adds cost and complexity. It also does not include a pump or faucet, so you’ll need to purchase those separately. Skip this if you prefer a standalone tank with an integrated spigot.
- Modular design integrates with Front Runner cargo system
- Includes brass water outlet and vent cap
- Low-profile shape fits under most bed racks
Pros: Excellent build quality and UV resistance; Modular mounting is very secure
Cons: Requires Front Runner rack system for optimal mounting; No pump or spigot included
3. WaterPORT 10 Gallon Water Storage Tank: Best All-in-One with Pump
The WaterPORT 10 Gallon Water Storage Tank is a popular all-in-one solution for campers who want pressurized water without the hassle of gravity systems. It includes a 12V pump powered by 4 D-cell batteries, a 6-foot hose, and a spray nozzle. Owner feedback often praises its ease of use and convenience for washing dishes, showering, and cleaning gear.
One notable weakness is the pump’s vulnerability to water ingress if the cap is not sealed properly. Some users reported pump failure after exposure to rain. Skip this if you camp in consistently wet conditions or prefer a simpler gravity-fed system.
- Integrated 12V pump delivers pressurized water on demand
- Rugged blow-molded polyethylene tank with UV inhibitors
- Includes 6-foot hose, spray nozzle, and quick-connect fittings
Pros: Pressurized water without gravity or manual pumping; Complete kit with everything needed
Cons: Pump is not submersible and may fail if water gets into battery compartment
4. Scepter 5 Gallon Military Water Can: Most Durable
The Scepter 5 Gallon Military Water Can is the gold standard for durability. Made from thick HDPE and built to military specifications, it can withstand extreme temperatures, impacts, and UV exposure. Owner feedback from overlanders and off-road enthusiasts consistently rates it as the most reliable water container for rugged use.
However, its weight when full (over 40 lbs) can be cumbersome to handle, and the spout design is not as fast as modern nozzles. It also lacks a built-in spigot or pump, so you’ll need to pour or use a separate dispensing system. Skip this if you prioritize convenience over ultimate durability.
- Mil-spec construction with thick HDPE walls
- Stackable design with interlocking ribs
- Includes a locking spout and vent cap
Pros: Nearly indestructible; Trusted by military and overlanders
Cons: Heavy when full (over 40 lbs); Spout can be slow to pour
5. GoWesty 7 Gallon Water Tank: Best for Vans and Small Trucks
The GoWesty 7 Gallon Water Tank is designed with van conversions and small truck beds in mind. Its rectangular shape maximizes storage efficiency, and the FDA-approved polyethylene ensures water stays fresh. Owner feedback highlights its leak-free construction and the convenience of the included brass spigot for easy dispensing.
However, the tank does not come with mounting brackets or straps, so you’ll need to secure it yourself. The spigot also lacks a lock, which could be a concern if you drive off-road. Skip this if you need a tank with integrated mounting solutions or a locking mechanism.
- Low-profile rectangular shape fits under benches or in tight spaces
- FDA-approved food-grade polyethylene
- Includes a brass spigot and vented cap
Pros: Space-efficient shape; Food-grade material ensures safe drinking water
Cons: No mounting hardware included; Spigot is not lockable
6. Rugged Ridge 6 Gallon Water Tank: Best for Jeep Trucks
The Rugged Ridge 6 Gallon Water Tank is a budget-friendly option tailored for Jeep Gladiator owners. It fits neatly behind the rear seat or in the truck bed. Owner feedback notes that it works well for basic hydration needs and is easy to handle when empty.
However, the plastic walls are thinner than those of premium tanks, leading to some reports of cracking under extreme cold or impact. The pour spout is also plastic and may wear over time. Skip this if you need a heavy-duty tank for frequent off-road use or extreme temperatures.
- Designed to fit behind Jeep Gladiator seats or in bed
- Includes a pour spout and vent cap
- Made from UV-resistant polyethylene
Pros: Fits specific Jeep models perfectly; Lightweight when empty
Cons: Thin walls compared to competitors; Pour spout is not as durable as brass or metal
7. Titan Fuel Tanks 20 Gallon Water Tank: Best Large Capacity
The Titan Fuel Tanks 20 Gallon Water Tank is designed for serious overlanders who need a large water supply. Its rotomolded construction is extremely tough, and the generous filler neck makes filling easy. Owner feedback from long-haul campers praises its capacity and durability, noting it can withstand rough terrain without leaking.
However, the tank weighs over 160 pounds when full, requiring a sturdy mounting system and possibly a helper to install. It also lacks any dispensing hardware, so you’ll need to add a pump or gravity-fed spigot. Skip this if you have a small truck or don’t need that much water.
- Large capacity for extended camping trips
- Rotomolded polyethylene with thick walls
- Includes a 2-inch filler neck and 1-inch vent
Pros: Massive water storage for groups or long trips; Very durable construction
Cons: Very heavy when full (over 160 lbs); No pump or spigot included
Frequently Asked Questions
What size water tank do I need for camping?
The ideal size depends on your trip duration and group size. For a weekend solo trip, 5-10 gallons is usually enough. For a family of four on a week-long trip, consider 15-20 gallons. Always factor in water for drinking, cooking, cleaning, and possible showers.
Can I use a truck bed water tank for drinking water?
Yes, but only if the tank is made from food-grade materials like FDA-approved polyethylene. Many tanks are labeled as potable water safe. Avoid tanks not explicitly marked for drinking water, as they may leach chemicals.
How do I secure a water tank in my truck bed?
Most tanks come with mounting holes or brackets. Use ratchet straps, tie-downs, or a cargo bar to secure the tank to the bed. For larger tanks, consider bolting them to the bed floor or using a custom mounting system. Always ensure the tank cannot shift during driving.
What is the best material for a truck bed water tank?
Rotomolded polyethylene is the most common and durable material. It is UV resistant, impact resistant, and food-safe. Some tanks use blow-molded plastic, which is lighter but less durable. Avoid metal tanks as they can rust or corrode.
Do I need a pump or can I use gravity?
Gravity-fed systems work well if the tank is mounted higher than the point of use, such as on a roof rack or raised platform. For truck bed tanks, a pump is often more convenient for pressurized water. Battery-operated 12V pumps are popular and easy to install.
