Take your van build to the next level with the Avatar Offroad Mega Van Rear Door Storage Box—a rugged, high-capacity storage solution designed for overlanders, off-grid explorers, and gear haulers. Crafted from heavy-duty aluminum and finished in sleek black powder coating, this box is built to withstand the toughest trails while delivering functional style. Mounting easily to most adventure van rear doors, the Mega Box offers ample storage for tools, camp gear, and outdoor essentials. A built-in flip-down shelf transforms into a convenient workspace—perfect for prepping meals or setting up camp. Engineered for real-world conditions, it keeps your gear protected from water, dust, and the elements.
Integrated Flip-Down Shelf: Creates an instant outdoor kitchen or work surface—perfect for stoves, prep, or gear staging.
Heavy-Duty Build: Made from high-strength aluminum with a durable black powder coat for long-term durability and sleek style.
Adventure-Ready Design: Water- and dust-resistant with easy rear-door installation on most vans & built to handle real offroad conditions.
A Rear Door Mounting Product is required.
