Canvas Canopy or Lockable Tonneau: How to Cover the 2026 INEOS Grenadier Quartermaster’s Cargo Bed

October 20 2026,

The 2026 INEOS Grenadier Quartermaster is the pickup of the Grenadier family. It’s a five-seat double cab with a cargo bed large enough to carry a standard Euro pallet. Once you start loading that bed with tools, camping gear or work equipment, one question comes up fast: how should you cover it?

INEOS offers two Quartermaster-only answers in its accessory range: a sturdy frame with a waterproof canvas canopy, and a lockable roller tonneau cover. Each one suits a different kind of load and a different kind of owner. This guide compares the two and helps you match the cover to the way you work and travel.

Start With the Bed Itself

Before you choose a cover, it helps to know what you’re covering. The Quartermaster rides on an extended 3,227 mm wheelbase, which is 305 mm longer than the Station Wagon’s. That extra length goes straight into the cargo bed:

Bed length of 1,564 mm, width of 1,619 mm and height of 485 mm
Room for a standard 1,200 mm x 800 mm Euro pallet
Payload of up to 1,841 lbs (835 kg)
A wide 1,280 mm tailgate that supports up to 496 lbs (225 kg) when open

The bed also includes four tie-down rings, a 400 W power take-off and an integrated mounting bar. Those features make it easy to strap down loads and run small electrical gear, no matter which cover you pick.

The Canvas Canopy: Weather Protection for Outdoor Gear

The canvas canopy uses a robust frame to support a waterproof canvas cover over the bed. It keeps rain, snow and road spray off whatever you’re carrying.

This setup works well for owners who load soft, bulky items: tents, sleeping bags, coolers, duffels and outdoor equipment. If your weekends involve long drives to a campsite or a cottage, the canopy keeps that gear dry from the driveway to the destination.

The canopy also suits owners who use the Quartermaster as a mobile base. Farmers, land managers, outfitters and outdoor guides often need to keep supplies covered while they work across a property or trail system.

The Lockable Roller Tonneau: Security for Tools and Equipment

The roller tonneau cover slides across the top of the bed and locks. Once it’s closed, your cargo is hidden from view and secured behind the lock.

That makes the tonneau the better choice for owners who leave valuable items in the bed. Tradespeople carrying power tools, contractors hauling equipment between job sites and anyone who parks in busy lots will appreciate being able to lock the bed and walk away.

Because it’s a roller cover, it slides back when you need the full bed for a taller load, then closes again to lock everything away.

Other Ways to Add Carrying Capacity

A bed cover isn’t the only way to expand what the Quartermaster can haul. INEOS also offers cross bars for the cargo bay, and the Grenadier’s reinforced roof comes with built-in roof rails and protection strips as standard.

For regular roof loading, the optional Rhino Rack roof rack has a static load rating of 926 lbs (420 kg) and a dynamic load limit of 331 lbs (150 kg), both including the weight of the rack itself. Pair that with the Quartermaster’s 7,716 lbs (3,500 kg) braked towing capacity, and you can bring a trailer along for the largest jobs.

Which Cover Is Right for You?

Both covers do their job well. The right choice depends on what usually rides in your bed:

Choose the canvas canopy if you mostly carry camping gear, sports equipment or soft bags that need protection from the weather
Choose the lockable roller tonneau if you carry tools, equipment or anything you want locked away when the truck is parked

INEOS designed its accessories so owners can fit them easily, or have them installed through the INEOS aftersales network. Every accessory in Canada is backed by a three-year warranty, so your cover is protected long after installation.
