By Audrey HayesUpdated November 2026
Water storage for overlanding is one of those gear decisions that looks simple until you are three days into a remote loop with a dry camp ahead. The right container depends on how much water you actually need, how your vehicle has room to carry it, whether it has to sit in the sun all day, and how you plan to get water out of it at the campsite. This guide compares seven widely sold containers across those criteria. We looked at manufacturer specifications, brand reputation for materials and leak resistance, and the patterns owners tend to report about spigots, handles, mounting and long-term durability. We have not run these containers through field tests of our own, so treat the notes below as a research summary rather than hands-on results.

Buying Guide
Capacity and Days Between Refills
Plan on a minimum of about one gallon per person per day for drinking and basic cooking, and more if you also wash or run a hot-water system. Multiply that by your planned days without a refill point, then add a reserve for delays. Many overlanders carry at least three to five days of supply for remote routes.
Good picks for this: 5 Gallon Water Jug, Camping Water Container; 6.6 Gallon Water Tank with Faucet
Mounting Method and Vehicle Load Limits
Filled containers are heavy. A five-gallon container weighs roughly 42 pounds when full, and larger tanks add considerably more. Check your roof rack, bed rail or bumper-mounted carrier’s rated capacity before mounting, and keep the load low and centered where possible.
Good picks for this: 8 Gallon 30L Storage Container with Lockable Bracket; 5-Gallon Stackable Water Storage Containers
Material and Taste Safety
Look for food-grade plastics such as HDPE and labels stating BPA-free construction. Avoid containers that previously held non-food chemicals, and do not use a container for fuel or fluids other than water. Reserve some containers for drinking water only.
Good picks for this: 5 Gallon Water Jug, Camping Water Container; UPWOIGH 3.5 Gallon Water Jug
Dispensing Method
A spigot prevents spills and lets you fill cups or pots at waist height. A pump reduces effort but needs power. Gravity-only taps are simpler and more reliable in dusty conditions. Consider which method suits your camp routine.

Weight and Portability
Measure both the empty weight and the full weight. A container you can lift safely at camp is more useful than a bigger one you avoid filling. Wheels help on firm ground but can bog down on sand, so match the design to your terrain.
Good picks for this: GIGYES Rolling Wheel Water Storage Tank; Lightweight Durable water can with carry handle
Durability and UV Exposure
Sun exposure degrades plastic over time and can warm water to uncomfortable temperatures. Store containers in shade when possible, inspect seals and caps before each trip, and replace any container with cracks or brittle sections. Keep the container out of direct contact with hot exhaust components.
Good picks for this: 8 Gallon 30L Storage Container with Lockable Bracket; 5-Gallon Stackable Water Storage Containers
Cleaning and Water Quality
Rinse containers before first use and periodically between trips. Use a mild, unscented cleaning solution and rinse thoroughly. Treat water from unknown sources before drinking, and follow local guidance on filtration or purification. For health-specific questions about water safety, consult a qualified professional or local health authority.

FAQ
How much water should I carry for an overlanding trip?
A common planning figure is about one gallon per person per day for drinking and cooking, with extra for washing, pets and any vehicle or cooling needs. Add a reserve of at least one extra day in case of delays or closed water points.
Should I mount my water container on the roof or inside the vehicle?
Interior storage keeps weight lower and protects containers from sun and debris, but it uses cargo space. External mounting frees room inside. Check your rack’s rated load and secure the container so it cannot shift on rough roads.
Can I use a water jug for fuel or other liquids?
No. Containers used for drinking water should be dedicated to that purpose. Fuel, oil and other chemicals can contaminate the plastic and make the water unsafe.
How do I keep stored water from going bad?
Store containers in a cool, shaded spot, keep them sealed, and empty and rinse them periodically. Replace water on a regular schedule rather than letting it sit for long periods, and inspect containers for odor or cloudiness before use.
Is a spigot better than a pump for camp use?
A spigot is simple and needs no power, making it reliable in remote settings. A pump is easier on your hands but depends on a charged battery. Many overlanders prefer a spigot as the primary method and keep a pump as an option.
What is the best size for solo overlanding?
For one person on a short trip, a two- to five-gallon container is usually enough, supplemented by a backup supply. Larger tanks make more sense for couples or groups with fixed camp routines.
How heavy is a full five-gallon water container?
Water weighs about 8.3 pounds per gallon, so a full five-gallon container weighs roughly 42 pounds before counting the container itself. Plan your vehicle load and mounting accordingly.
Conclusion
There is no single best container for every overlanding setup. A five-gallon spigot jug is a flexible default for most people. Stackable units suit organized cargo areas, a lockable bracket model suits rack-mounted builds, and a two-gallon can works well as a backup or solo supply. Larger faucet tanks fit fixed camps, rolling tanks help on firm ground, and a dual-dispensing jug covers pour-free camp use. Start with your daily water need, your mounting options and your typical days between refills, then choose the container that matches.
