INEOS Grenadier Cargo Storage & Drawer Systems: Every Option Compared, What Actually Fits & What Owners Recommend

Every Grenadier owner hits the same realization within the first week: the loadspace looks generous until you start filling it. Recovery gear, a fridge, camping supplies, tools — it all piles into one undivided cavern behind the rear seats, and within a few corrugated miles, everything has migrated to the wrong side of the cargo area.

The deeper problem is geometry. The Grenadier's cargo depth — the distance from the tailgate opening to the back of the folded rear seats — measures roughly 32 inches. That's noticeably shorter than a full-size SUV, and it constrains every drawer system, fridge slide, and platform you'll consider. Get the measurements wrong, and you're returning expensive gear or living with a system that blocks the seats from folding.

We dug through four years of owner builds on The INEOS Forum to map every approach that's actually working — and the trade-offs each one demands.

The Core Problem: 32 Inches Changes Everything

Most aftermarket drawer systems are designed for pickup truck beds — 48 to 60 inches of depth. The Grenadier's compact cargo bay requires purpose-built solutions or significant modification. As one owner discovered after installing a secure storage vault:

Because of the Grenadier's short depth of cargo area of only about 32 inches, I am glad that it is the taller height of 10 inches inside for more storage that is accessible with the pull-out drawer.

— Jeff, The INEOS Forum, "Truck Vault Installed" thread

That 32-inch constraint is the single most important number for any cargo storage decision. Every system reviewed here works within it — or works around it by extending over the folded rear seats.

Five Approaches to Grenadier Cargo Storage

INEOS now offers a factory-option drawer system through the vehicle configurator. It's the simplest path if you want a guaranteed fit, but it comes with a notable trade-off.

• Capacity: Up to 90 kg of contents inside a large, lockable drawer
• Key feature: Creates a full flat floor when the rear bench is folded forward
• Trade-off: Requires removing the Interior Utility Rails to install
• Price: Approximately £1,961 / ~$2,500 USD through the INEOS configurator

Losing the utility rails is significant. Those rails are attachment points for cargo nets, dividers, and L-Track compatible accessories. If you rely on them for day-to-day cargo management, the OEM drawer effectively trades one organizational system for another. If your Grenadier didn't come with factory utility rails — or you need to replace worn ones — DVA's Interior Utility Rails are a direct bolt-on upgrade in 6061 anodized aluminum that actually exceeds OEM spec.

The most popular first upgrade among Grenadier owners isn't a drawer at all — it's the cargo baskets that mount in the otherwise wasted space between the wheel wells and the cargo area walls. Multiple manufacturers now offer Grenadier-specific versions.

I have the Bison-Gear baskets and they are worth every penny.

These baskets turn dead space into usable storage without consuming any floor area. They're ideal for recovery straps, first-aid kits, tools, and other gear you want accessible but not rolling around the cargo bay.

One owner's setup illustrates how this approach scales:

I got the overland gear guys pouches for the metal inserts molle panel on the side in the trunk. Got recovery gear in one pouch, some first aid in another. I put a radio pouch with molle mount on the side of the left panel together with a molle eyeglass holder for safety glasses... Really happy with how it's coming together.

— Parb, The INEOS Forum, "Rear Cargo Storage" thread

The combination of side baskets, a rear cargo shelf, and MOLLE-compatible panels gives you organizational structure without any permanent floor-space commitment. For owners who need the cargo bay to flex between overlanding trips and daily errands, this modular approach is hard to beat.

For dedicated overlanding builds, a full drawer system with an integrated fridge slide is the gold standard. Several Grenadier-specific options are now available, and custom builds are common.

One owner built a system that combines all the critical elements within the Grenadier's tight dimensions:

The fridge is removed and a drop-in shelf is bolted in. As a full platform the metal edging is hidden by foam mats and a sheet of carpet. Drawer is on Teflon-like runners. I have a 36L water tank behind the drawer system. It sits slightly proud and lines up with the cargo barrier.

— Yippe, The INEOS Forum, "Front Runner Storage System" thread

The economics of custom versus off-the-shelf matter here. That owner's build — including fridge slide, water tank, materials, and fixings — came to just under $1,000 AUD. Pre-built Grenadier-specific systems from manufacturers typically run $2,000–$4,000+ USD depending on features and materials.

A collaborative build from three forum members — Jaro, Pavo, and inky_black — produced one of the most documented and replicated Grenadier storage solutions. Their system uses standardized Euro crates as the organizing principle, with purpose-built drawers sized to accept them.

The design specifications are precise:

• Two pull-out drawers with heavy-duty slides and sturdy plywood frames
• Euro crate compatibility: Accepts both 400×300×120 mm and 600×400×120 mm standard sizes
• Profile height: Only 180 mm total — maintains flat loading surface when rear seats fold
• Lockable drawers that open and close with one hand
• Expandable: A plug-in bed setup mounts directly on top without compromising vehicle functions

The Euro-crate approach solves a problem that plagues freeform drawer systems: you can swap crates between trips. A camping crate, a recovery crate, a tools crate — each pre-packed and ready to slide in. The standardized dimensions mean you can source replacement crates anywhere in the world.

The 180 mm system height is critical. At that profile, the drawers sit low enough that folding the rear seats still creates a roughly level surface — which is what makes the bed conversion possible. Go much taller, and you lose that capability entirely.

Sportspeople and owners who carry firearms need lockable, secure storage that goes beyond what standard drawer systems offer. Carpet-lined vault systems designed for gun storage fit the Grenadier — but that 32-inch depth constraint shapes every choice.

My thoughts are they are suited for those of us sportspeople who have expensive handmade guns that want them locked up and secure and protected from getting beat up, thus they are carpet-lined. If I were an off-roader who has fridges with slide-outs, there would be other manufacturers' systems that would be more applicable.

— Jeff, The INEOS Forum, "Truck Vault Installed" thread

Available drawer depths in vault systems typically range from about 6.5 to 10.5 inches. For the Grenadier, the maximum depth works best — you're already constrained on horizontal space, so vertical capacity matters. The trade-off is height: a 10-inch-deep vault plus platform sits tall enough that you'll need wing panels to fill the gaps between the vault and the wheel wells.

The Bed Question

Every cargo storage thread eventually arrives at the same question: can this system double as a sleeping platform? The answer depends on your height and your tolerance for compromise.

I look at the bed option then wonder if I use it, then where do I store all of the "might be needed" gear I brought along... Unless it's like Schrödinger's cat and the bed and gear and me can all exist in the same space.

— DenisM, The INEOS Forum, "Rear Storage & Bed" thread

The practical answer from owners who sleep in their Grenadiers: remove the rear seat bottom cushions (held by a few fasteners), fold the seatbacks flat, and place storage boxes behind the folded seats to create a level surface. Add a 6-foot mattress and you have a functional sleeping setup — if you're under six feet tall.

For taller owners, a purpose-built platform that extends over the folded seats and integrates with a rear drawer system is the better path. The Euro-crate system described above was specifically designed with this conversion in mind — the 180 mm profile preserves enough headroom for sleeping while still providing drawer storage underneath.

Five Common Mistakes

1. Buying truck-bed drawer systems and hoping they fit. The Grenadier's 32-inch cargo depth is shorter than nearly all pickup beds. Measure twice, order once — or buy Grenadier-specific.
2. Ignoring the utility rail trade-off. The OEM drawer requires removing utility rails. If you depend on those rails for nets, dividers, or L-Track accessories, you need a different approach — or plan to reinstall upgraded rails later.
3. Blocking seat folding. Any system taller than roughly 180 mm (7 inches) will interfere with folding the rear seats flat. If you need that flexibility, measure the system height against your seat-fold clearance before buying.
4. Forgetting weight adds up. A full drawer system, fridge, water tank, and loaded crates can easily reach 80–100 kg. That comes directly from your payload budget. Every kilogram in the cargo bay is a kilogram you can't carry on the roof or tow.
5. Overbuilding for trips you rarely take. Side baskets and a cargo shelf handle 90% of daily-use organization for a fraction of the cost and complexity of a full drawer system. Build for how you actually use the vehicle, not how you imagine using it.

The Bottom Line

The Grenadier's cargo bay rewards thoughtful planning and punishes impulse purchases. Start with the cheapest reversible option — side baskets and a shelf — live with it for a few trips, and let your actual usage pattern guide the next upgrade. For many owners, DVA's Interior Utility Rails are the logical first step: bolt-on L-Track rails that give you a flexible cargo mounting foundation without committing to a drawer system. The owners who are happiest with their setups are the ones who built incrementally, not the ones who ordered everything at once.
