Free Shipping to the Lower 48

Meet the Giga Box™, the largest and most innovative van storage box on the market—engineered for adventurers, vanlifers, overlanders, and pros who demand both maximum capacity and intelligent design. With a massive 13 cubic feet (370L) of main body storage—plus bonus internal door cavity space—this box lets you carry all your essential gear without compromising weight or function.

Built to withstand off-road abuse and unpredictable weather, the Giga Box™ isn't just a storage box—it's a mobile command center. Its lower door folds down to become a heavy-duty cooking station or mobile workbench, perfect for trail meals, surfside breakfasts, or remote repairs.

We’ve integrated a custom Avatar-designed L-track system directly into the box walls. This not only lowers weight and increases durability, but also allows for shelf adjustability and tie-down versatility using standard L-track accessories. Every feature serves a dual function—no wasted space, no wasted weight.

Key Features:

• 13 cu ft (370L) of storage plus bonus door cavity space

• Fold-down multifunctional door for cooking or work surface

• Constructed from lightweight, high-strength aluminum with black powder coat

• Custom integrated L-track system for adjustable shelving & gear tie-downs

• Water & Weather-resistant and dust-sealed for all-condition reliability

• Designed for Massif and Sir Packs-A-Lot mounting systems

• Optional handle extension for passenger side Sprinter or Transit install

Embrace the call of the wild and conquer every challenge with the Giga Box™: where ingenuity meets durability, making every trip an unforgettable experience!
