Turn your Grenadier's trunk into a fully organized, expedition-ready storage command center — without drilling a single hole.
The Mammoth Vault is reverse-engineered directly from OEM vehicle data for a 100% non-destructive, plug-and-play installation. Every mounting point matches factory tolerances, so there's no cutting, drilling, or permanent modification required.
Built to carry the load. The drawer frame is CNC-bent aluminum alloy reinforced with a stainless-steel support structure, fully welded for maximum rigidity. Paired with heavy-duty sliding rails, each drawer supports up to 200 kg — enough for recovery gear, tools, water, and camp kitchen setups combined. Adjustable internal dividers let you customize the layout for whatever you're hauling.
Mount anything on top. The upper surface features four quick-release, heavy-duty rail tracks precision-CNC-machined from 6061 aluminum alloy, giving you a secure quick-mount platform for fridges, storage boxes, or additional luggage.
Lightweight where it counts. Both the drawer face and top panel are multi-layer marine-grade plywood, CNC-cut and finished with AT-X protective coating — abrasion-resistant, moisture-resistant, and light enough to keep your payload efficient.
Sleep anywhere. Combined with the front seats folded flat, the Vault forms a full flat sleeping platform for overnight camp stops — no separate sleeping platform kit needed.
More space, not less. A stock Grenadier trunk fits 3 suitcases. With the Mammoth Vault installed, it fits 4 — smarter packaging, not a smaller trunk.
Whether you're outfitting for a weekend trail run or a cross-continent overland build, the Mammoth Vault gives your Grenadier the structure, capacity, and versatility to carry it all.
