The stock INEOS Grenadier stands out as an exceptional expedition platform built upon rigorous mechanical authenticity and a rugged ladder-frame layout. Yet, the moment you attempt to sleep inside the cabin or stack square camping crates in the rear, you confront an immediate engineering bottleneck. Because the second-row passenger seats do not fold entirely flat, they leave a pronounced, awkward step right in the center of your trunk space. This factory oversight quickly turns methodical gear packing into cabin clutter and derails any plan for an effortless, trailside sleep setup.
To eliminate this storage headache, we developed two specialized heavy-duty rear organizer layouts—but choosing the right one requires evaluating two distinct design directions. One blueprint prioritizes a perfectly flush, level foundation tailored for interior car camping, while the other channels all its utility into delivering maximum secured storage volume. A frequent concern we hear from the global overlanding community is: "If I raise the trunk floor, will I lose too much vertical headroom to comfortably sit up inside the truck?" Selecting the incorrect setup means either sacrificing valuable vertical clearance or missing out on massive drawer space. Let's break down the technical blueprints so you can deploy the precise tool for your lifestyle.

The Interior Camping Setup: Low-Profile Twin Drawer System
For overland explorers looking to establish a modular, secure sleeping platform directly inside the vehicle cabin, our Low-Profile Twin Drawer System serves as the ideal mechanical solution. Engineered with a heavily optimized, compact height matrix, the top deck of this platform aligns flawlessly with your folded rear passenger seatbacks. This creates a continuous, unbroken sleeping bay where you can spread out an off-road mattress immediately, entirely bypassing the need for custom plywood levels or cumbersome spacer blocks. It transforms your Grenadier into a hard-sided, weatherproof tactical shelter during heavy trail storms or remote backcountry expeditions.
Because this low-profile chassis sits closer to the floor to maximize cabin headroom, you accept a minor strategic tradeoff in absolute internal storage volume. The twin independent, smooth-gliding drawers offer 32L of lockable storage space to keep your essential gear organized and safe. This layout is perfect for stowing recovery gear, camp kitchen utensils, and compact hand tools that demand quick access and solid security. To compensate for the shallower internal drawer height, the top platform is fabricated from rugged steel and outfitted with three integrated cargo tracking rails. These metal tie-down tracks allow you to confidently anchor heavy external payload cases, overland refrigerators, or stacked luggage using standard tie-down straps, expanding your utility footprint externally.
Vehicle integration is engineered to be entirely painless, acting as a non-destructive plug-and-play modification that respects your long-term vehicle investment. It fastens directly into your existing factory cargo tie-down points using standard workshop tools. There is absolutely no need to drill permanent holes into your steel body panels or slash your factory floor carpet. If you ever decide to remove the platform before trading in your vehicle, you can unbolt it in a matter of minutes and return the rear compartment to pristine factory condition, fully protecting your residual value.
The Heavy Payload Vault: Full-Size Rear Trunk System
For operators and professionals who permanently carry a massive payload of heavy mechanical tools, recovery winches, and extensive overlanding gear, the Full-Size Rear Trunk System stands out as the premier high-capacity option. We engineered this variant with an extended height profile to unlock maximum internal cargo space. The system features two massive, deep-vault drawers that glide open effortlessly even when packed to maximum weight capacity, providing an armored mechanical locker to cleanly organize large toolkit cases, recovery straps, and air compressors that would otherwise slide around loosely in an open trunk area.
The expansive top deck is finished in a premium, noise-dampening tactical carpet that absorbs harsh trail vibrations and prevents loose metal gear boxes from clattering against the frame while tracking straight on high-speed highways. Flanking this carpeted surface are two integrated heavy-duty cargo tracking rails, allowing you to slide tie-down rings into position and lock down heavy refrigerator slides or secondary battery setups with absolute confidence.
However, you must evaluate the structural tradeoffs before opting for this high-capacity setup. Because it is designed with an elevated height profile to double your internal storage room, the top surface sits noticeably higher than your folded second-row passenger seats. This height offset means you cannot establish a completely flat, level interior floor for sleeping without additional padding modifications. Furthermore, the installation process is more complex than the twin system, requiring a multi-stage modular assembly sequence to secure the vault firmly into the factory floor structure. This robust layout is precision-tailored to fit the five-door Station Wagon model perfectly.
Choosing Your Mission Hardware: Flat Bed vs. Maximum Volume
Selecting your ultimate setup ultimately comes down to your primary field mission. We do not recommend trying to compromise between an interior sleeping platform and maximum deep drawer storage; instead, you must clearly define your overlanding profile before investing in trunk hardware:
Deploy the Twin Drawer System if you run a self-reliant overland build centered around interior vehicle camping. It yields a flat, solid foundation to sleep out trail storms inside the insulated cabin while keeping emergency gear locked securely underneath. The three integrated steel rails on top make it incredibly simple to anchor secondary cargo blocks when traveling, maintaining your stealth camping capabilities on remote tracks.Deploy the Full-Size Rear Trunk System if you are an expert builder or commercial operator carrying recovery equipment, heavy winches, and massive payloads permanently in the cargo bay. You trade away the flush interior mattress feature, but you gain unmatched internal deep-vault organization. The noise-dampening carpet layer ensures your cabin remains quiet and professional while eating up long highway miles.
The choice narrows down to one definitive question: do you sleep inside your vehicle, or do you carry heavy tactical gear? Configure your overland setup at Plomor today—order the Twin Drawer System for a flush sleeping sanctuary, or the Rear Trunk Drawer System for maximum secure vault capacity.
