Add practical exterior gear storage to your Winnebago ARKA with the Black River Rear Exterior Storage Box. Built from automotive-grade aluminum and finished with a durable black powder coating, this box provides a dedicated place for tools, campsite equipment, recovery gear, travel supplies, and other items you would rather keep outside your living space.
The Rear Exterior Storage Box is designed to mount to the Black River Passenger-Side MOLLE Plate System. The MOLLE Plate System is required for installation and creates a strong, integrated mounting location on the exterior of the ARKA.
Exterior Storage for the Winnebago ARKA
Interior space matters when traveling in an RV. The Rear Exterior Storage Box helps preserve that space by moving appropriate gear outside the vehicle while keeping it organized and easy to reach.
It is especially useful for muddy straps, dirty tools, hoses, power cords, recovery equipment, campsite supplies, and other bulky essentials that can clutter the interior. Giving this equipment a dedicated exterior location helps keep the ARKA’s living and storage areas cleaner and easier to use.
Mounts to the Passenger-Side MOLLE Plate System
This storage box is purpose-built to install on Black River’s Passenger-Side MOLLE Plate System. It does not mount directly to the RV by itself.
The MOLLE Plate System provides the required exterior mounting foundation and allows the storage box to become part of a clean, coordinated ARKA outfitting setup.
Durable Aluminum Construction
Automotive-grade aluminum gives the Rear Exterior Storage Box strength without adding unnecessary weight. Its black powder-coated finish provides a durable exterior surface and creates a clean, rugged appearance that complements the ARKA and other Black River outfitting products.
The materials and finish are selected for real-world RV travel, where storage equipment may experience changing conditions, regular use, dirt, and road debris.
Built for Real-World Travel
The Rear Exterior Storage Box is useful for more than extended overland trips. It adds convenient gear storage for weekend camping, road trips, hunting, fishing, campsite setup, property work, and everyday travel.
If an item needs to remain close to the vehicle but does not belong inside the living area, this box gives it a designated place.
