Oasis Tank

The Duo does something no other roof rack accessory can: it gives you fresh water and extra cargo space in a single unit. Water tank on the bottom, cargo platform on top — no compromises, no choosing between one or the other.

Designed for families and adventurers who drive SUVs and sedans, the Duo turns your roof rack into a complete base camp. Pack your gear on top, plug in the pump below, and hit the road with everything you need — including 10 gallons of pressurized fresh water for the journey.

Engineered and manufactured in Costa Rica. Built for wherever life takes you or your family.

Note: The Duo is designed for external use — rinsing, washing, and cleaning. Not intended for drinking water.

Note: The 220 lb cargo capacity refers to evenly distributed load and does not include the weight of water. We recommend verifying your roof rack's weight limit before installation, as most standard racks support 155–220 lbs. The Duo filled with water weighs approximately 132 lbs.

Water Tank and Cargo Platform. One Product. Stop choosing between carrying water and carrying gear. The Duo combines a 10-gallon roof-mounted water tank with a full-size cargo platform — giving your family more of everything without taking up more roof space.

10 Gallons On Demand  Fresh water, always ready. Enough to rinse off the kids after a beach day, wash the dog, clean muddy boots, and shower off before the drive home — all from the same trip.

70 PSI Built-In Electric Pump Powerful, consistent water pressure at the push of a button. Simply connect the 12V cable to your vehicle and the Duo is ready to go — no external pressurization, no effort.

Gravity Access Need water fast without connecting to power? The manual shut-off valve gives you instant gravity-fed access — perfect for a quick rinse or emptying the tank.

220 lb Cargo Platform The top surface handles up to 220 lb of evenly distributed gear — luggage, coolers, camping equipment, sports gear, you name it. Six integrated tie-down points keep everything secure on the road.

Generous Cargo Space 47.2" × 29.1" of usable cargo surface — enough room for the gear your car simply can't fit inside.

Universal Roof Rack Compatibility Custom-engineered mounting hardware fits standard roof racks on SUVs, crossovers, and sedans. Everything you need for installation is included.

Complete Kit Included 12V cable, high-pressure 3-function shower hose, upper and lower mounting flanges with all hardware, and an accessories bag to keep everything organized.

Available in: Black, Red, and Gray

Dimensions: 57.5" L × 32.1" W x 5.31" H
