Expedition HQ | Crafting Turn-Key Overland Powerhouses

When preparing a heavy-duty touring 4x4 for the relentless realities of remote Australian travel, there is a massive difference between bolting on standard retail accessories and engineering an integrated expedition platform. Located on the Gold Coast, Expedition HQ (XHQ) serves as an authorised sales, service, and custom build agent for INEOS Automotive across Queensland and Northern Rivers NSW.

Long before the Grenadier landed in Australia, the family team behind Expedition HQ was already globally renowned for manufacturing SLRV Expedition Vehicles—multi-million-dollar, multi-axle, military-grade off-road motorhomes. When the Grenadier debuted, they immediately recognized a platform built on the same core principles they live by: an uncompromising focus on ladder-chassis utility, mechanical simplicity, and long-range durability.

Today, Expedition HQ consolidates their immense engineering expertise, their official INEOS dealership, and their elite XSPEC in-house customisation brand under one roof.

The "Tools, Not Toys" Philosophy

Expedition HQ approaches the Grenadier and Quartermaster platforms from a position of deep field experience. They don’t design modifications based on showroom aesthetics; they design them based on what survives thousands of kilometres of brutal outback corrugations, choking bull dust, and extreme isolation.

• Real-World R&D: The Boswerger family has spent decades breaking, repairing, and living out of vehicles in Australia's most remote desert corridors. Their engineering decisions are driven by field-testing, ensuring that modifications enhance—rather than compromise—the vehicle's original engineering intent.

• Total Integration: Rather than implementing disjointed, third-party bolt-ons that fight against the Grenadier’s complex electrical architecture and tight mechanical tolerances, Expedition HQ crafts seamless upgrades that interface perfectly with factory systems.

Signature Build Packages & The XSPEC Ecosystem

Expedition HQ is famous for its high-end, turn-key build packages. They take a factory-fresh Grenadier and elevate it into a self-sufficient, continent-crossing machine.

1. The SLRV XSPEC Editions (Touring & Expedition)

XHQ transforms standard Trialmaster or Fieldmaster wagons into highly specialised, long-haul tourers.

• Intelligent Storage: Features the custom-built XSPEC Drawer System. Built as a heavy, load-bearing structural storage solution rather than a glossy furniture piece, it is designed to slide smoothly even when completely caked in trail dust or loaded with heavy recovery gear.

• Advanced Water Management: Integrates food-grade water storage systems complete with 12V pressurized pumps, allowing for seamless, remote self-sufficiency.

• Premium Utilities: Curated integration of internal camp kitchens, small pantries, and premium refrigeration setups, flawlessly matched with premium rooftop accommodations.

2. XSPEC Quartermaster Tray & Canopy Systems

For owners of the Quartermaster Ute or Cab Chassis variants, XHQ fabricates some of the most advanced tray options in the country. Their premium tray systems integrate heavy-duty, lockable under-tray toolboxes, a massive under-tray trundle drawer, and a 60L stainless steel food-grade water tank linked to a 12V pump feeding dual flush-mounted water outlets on both sides of the vehicle.

3. Curated International Aftermarket Access

Expedition HQ is a primary Australian pipeline for absolute top-tier global component brands, specifically engineering parts for the Grenadier. Through XHQ, club members can source and fit premium gear from:

• LeTech (Germany): Ultra-premium, heavy-duty rear door ladders and chassis-mounted protection.

• Agile Offroad (USA): Complete heavy-duty structural aluminium underbody skid plate packages.

• Chelsea Truck Company (UK): Exclusive visual styling, custom wider-track packages, and high-end interior conversions, including premium Nappa leather upholstery upgrades.

Showroom & Service Hub Details

Expedition HQ acts as a premier one-stop destination where club members can purchase a vehicle, establish a tailored custom build strategy, and maintain their logbook servicing through factory-trained mechanics.

Club Tip: Because the team at Expedition HQ builds vehicles meant for authentic exploration, they speak the exact same language as our club members. If you are planning a massive multi-week remote itinerary—such as our upcoming club crossing of the Simpson Desert—scheduling a consultation with XHQ to review your weight distribution, water storage infrastructure, and underbody armour is highly recommended.
