Rough Country 10L Flat Fluid Container Grey — Lockable Mount, Low-Profile 2.6 gal Storage for Trucks & Off‑Road

The Rough Country 10L (2.6 gallon) Flat Fluid Container is a lockable, mountable HDPE tank designed to safely store and transport non-potable water and utility fluids on trucks, SUVs, UTVs and overland rigs.

Built for off-road use, this low-profile container combines impact-resistant high-density polyethylene construction with a slim, space-saving shape and an integrated lockable mounting system. It’s intended for non-combustible liquids such as non-potable water, feed attractants, coolant, washer fluid, and other outdoor supplies where a secure, leak-free container is needed on rough trails or work sites.

How does the flat shape save vehicle space?

The flattened profile is designed to tuck against racks, MOLLE panels, or vehicle bodies so you can carry fluids without blocking cargo space or creating awkward protrusions. The shallow depth lets you mount it behind seats, under benches, or on bed rails while keeping center-of-gravity impact minimal.

• Dimensions: 18" x 13" x 4" — fits narrow mounting channels and shallow compartments.
• Low-profile design reduces snagging on branches and trail obstacles.
• Mountable attachments permit flush installation on racks and panels.

What keeps contents from leaking or spilling?

This container uses a seamless HDPE body and a threaded main sealing cap with a built-in pour spout to prevent leaks and enable controlled dispensing. A vent outlet relieves pressure changes during elevation shifts so fluid flows smoothly without sudden sprays.

• Seamless HDPE construction resists cracks and weak points.
• Sealing cap plus integrated pour spout minimizes mess while pouring.
• Vent outlet reduces pressurization during climbs and descents.

How does the lockable mount system protect the tank on rough trails?

The included mount attachments lock the container to your rack or panel so it won’t shift or fall during aggressive off-road travel. The hardware is built to remain secure under vibration and repeated impacts, giving you confidence when navigating rough terrain.

• Lockable mounting points secure to MOLLE, racks, and vehicle mounts.
• Hardware resists loosening under vibration and trail impacts.
• Compact footprint keeps the container stably positioned on the vehicle.

Is this safe for all liquids I might carry?

The Rough Country flat container is intended for non-combustible fluids such as non-potable water, washer fluid, coolant, and feed attractants. It is not rated for gasoline, diesel, or any combustible fuels — do not use it to store or transport fuel.

• Approved for non-potable water and various utility liquids.
• Not designed or certified for flammable or combustible fluids.
• HDPE resists UV and impact, but always follow fluid-specific storage guidelines.

Who is this for? Overlanders, weekend trail riders, worksite crews, and anyone who needs a compact, dependable fluid tank that mounts securely to a truck, SUV, UTV, or side-by-side. If you want a slim, rugged container to carry spare water, maintenance fluids, or attractants without sacrificing cargo space — and you need it to stay put on the roughest trails — this Rough Country 10L flat fluid container is built for that role.
