Flatline Van Co Adventure Van Wet/Dry Gear Box

The Van Rear Door Cargo Box is a rugged, weatherproof storage solution designed to mount securely on the outside of your Sprinter’s rear door. Crafted from powder-coated 2 mm aluminum, it keeps mud, sand, and firewood contained outside your van while maintaining a sleek profile that complements your build. Built for adventure, it stores wet or dirty gear without contaminating the interior.

Sized to fit 1–2 bundles of firewood or similar bulky items, the box features a secure locking latch and adjustable torque hinges that allow controlled opening. Drain slots in the bottom plate let water or debris escape, simplifying cleanup after muddy outings. Its compact design means it doesn’t block other accessories or interfere with rear door functionality.

Designed for easy customization, this box bolts directly to Flatline’s Rear Door Platforms—or compatible adapters—using stainless steel hardware. It’s a smart exterior storage upgrade for campers, overlanders, and work vans, keeping the mess out while providing durable and practical access to your gear.
