Rough Country 10L Flat Fluid Container Gray — Lockable Mountable HDPE, Low-Profile

The Rough Country 10L flat fluid container is a lockable, mountable HDPE tank designed to carry non-potable water and other outdoor fluids securely on trucks, SUVs, UTVs and RVs.

Built for off-road and overland use, this low-profile 2.6 gallon (10L) packable tank combines impact- and UV-resistant high-density polyethylene with an integrated pour spout, dual ergonomic handles, and quick-lock mounting hardware. Its slim footprint fits alongside gear, MOLLE panels and rack systems while the vented closure reduces pressure build-up on steep climbs or elevation changes. Note: it is not intended for gasoline, diesel or other combustible fuels — use it for non-potable water, feed attractants, and utility fluids.

How does this container stay secure during rough trails?

The container includes a dedicated lockable mount system that anchors to vehicle racks, MOLLE panels and other mounting points so it won’t shift or come loose on bumpy terrain. Built-in attachments line up with most side-by-side and overland gear racks, and the lock prevents theft or accidental detachment.

• Lockable mounting attachments for racks and MOLLE panels
• Low-profile flat design reduces snagging and keeps center of gravity low
• Durable HDPE construction resists impacts and abrasion from trail debris

What makes pouring and handling easier in the field?

Ergonomic grip handles on both the top and side allow controlled lifting and two-handed pouring even in awkward positions. A threaded main cap and integrated pour spout help direct flow and minimize drips, while the vent outlet equalizes pressure during altitude changes or heavy pouring.

• Top and side handles for safer balancing and pouring
• Sealing main cap with built-in pour spout for cleaner transfers
• Pressure-relief vent prevents glugging and splashing during use

How durable is the 10L tank for outdoor use?

Manufactured from high-density polyethylene, the container resists impacts, UV exposure and the wear that comes from repeated off-road use. The seamless body minimizes leak points and provides a rugged, easy-to-clean surface after muddy or dusty outings.

• Impact- and UV-resistant HDPE construction
• Seamless body design reduces leak risk and simplifies cleaning
• Lightweight yet sturdy — 5.5 lbs (2.5 kg) for the 10L model

What size and vehicle fits should I expect?

The 10L flat container measures approximately 18" x 13" x 4" (48 x 36 x 12 cm), designed to tuck into tight spaces along vehicle bodies and cargo racks. Rough Country also offers a larger 20L option if you need more capacity or plan longer trips.

• 10L (2.6 gal) size: 18" x 13" x 4", 5.5 lbs (2.5 kg)
• Color options include gray and military tan to match vehicle setups
• Compatible with trucks, SUVs, UTVs, side-by-sides, RVs and cargo racks

Who is this for: outdoor enthusiasts, overlanders, and working crews who need a compact, tough, and mountable container for non-potable water, attractants or utility fluids. If you want a slim-profile liquid tank that mounts securely to racks and survives rough conditions without adding much weight or bulk, the Rough Country 10L flat fluid container is built for that role.
