Isuzu D-MAX Canopy Guide: RT and RG, plus Holden Colorado

October 26, 2026

FORGED X makes two aluminium canopies for the Isuzu D-MAX dual cab: one for the RT series (2012–2019) and one for the current RG (2020 onwards). The RT tub is shared with the Holden Colorado RG, and the RG tub is shared with the Mazda BT-50 TF and the LDV T60 and T90, so the same canopies cover those utes too.

Which FORGED X canopy fits your D-MAX

Canopy	Series	Years	Notes
Isuzu D-MAX 2012–2019 canopy	RT50 / RT85	2012–2019	Same tub as the Holden Colorado RG
Isuzu D-MAX 2020-on canopy	RG	2020 onwards	Same tub as BT-50 TF and LDV T60/T90
Holden Colorado RG canopy	Colorado RG	2012–2020	Twin of the RT D-MAX

RT or RG?

The RT-series D-MAX (RT50 and RT85) was sold from 2012 to 2019. The current RG D-MAX arrived in 2020 with a new body and tub — it has slim, swept-back headlights and a much more angular front than the RT.

If your D-MAX was built around the changeover, check the compliance plate in the door jamb or send us your VIN and we will confirm which canopy fits.

Solid sides or dog windows on a D-MAX

The D-MAX is a common fleet and trade ute, and for that work solid sides are the usual choice — tools out of sight and no side glass to replace.

For an X-Terrain or LS-U set up for touring, the dog-window version gives kerbside access to the fridge and drawers and airflow through the tub when you are camped.

Both options have a glazed lift-up rear door on gas struts, marine-grade 5052 aluminium construction, seals and drainage around every opening for dust and corrugations, and a powder-coated matte black finish.

Holden Colorado RG

The RG Colorado (2012–2020) was developed alongside the RT D-MAX and shares its tub, so it takes the same canopy unit. It is listed as its own product so you can find it by name. The 2020-on D-MAX canopy does not fit the Colorado.

Weight, payload and roof load on the D-MAX

A FORGED X dual cab canopy weighs from around 60 kg, depending on the vehicle and the side option. Everything you add counts towards your D-MAX's GVM — the canopy, racks, drawers, water, fuel, passengers and gear — so add up the full setup and compare it with the payload on the compliance plate. Keeping the canopy light is what lets many owners stay within their factory GVM.

The roof is rated to 150 kg dynamic, while driving, and 300 kg static, while parked. Include the weight of your bars or rack in that total. A rooftop tent is fine on the D-MAX canopy as long as the tent and bars stay within 150 kg on the move, and the tent, bedding and occupants within 300 kg when parked.

Fitting a canopy to the D-MAX

Every FORGED X canopy clamps to the factory tub rail with the supplied hardware. There is no cutting and no drilling, and the canopy can come off again later with the D-MAX tub left as it was.

Fitting is available at our Slacks Creek centre in Brisbane — contact us to book and we will confirm the details for your vehicle. Canopies are also sent Australia-wide on pallet freight for fitting by your own installer. Spare seals, struts, glass and mounting hardware are held in stock at Slacks Creek.

Racks, tracks and locking

The roof has built-in tracks along its full length. Racks, awnings, recovery board mounts, solar panels and light bars bolt straight down, with no drilling. Yakima track-mount accessories have been tested as a direct fit with no adaptor plates, and the track profile also takes other common bolt-in systems.

An optional plug-and-play central locking kit connects to the D-MAX's existing wiring, so the factory key locks the cab and the canopy together.

D-MAX canopy questions

Will my RT D-MAX canopy fit a 2020-on D-MAX?

No. The RG D-MAX has a different tub.

Does the D-MAX canopy fit the Mazda BT-50?

The 2020-on D-MAX canopy fits the TF BT-50, which is built on the same platform. The older UP and UR BT-50 takes the PX Ranger canopy instead.

Does the D-MAX canopy fit the LDV T60?

Yes. The LDV T60 and T60 MAX share tub dimensions with the current D-MAX and BT-50.

Does the Holden Colorado take the D-MAX canopy?

The RG Colorado (2012–2020) takes the 2012–2019 D-MAX canopy unit. It is sold as its own Colorado product.

Do you make a D-MAX single cab or space cab canopy?

Yes, on request. The canopies listed in this guide are made for the dual cab tub, and single cab or space cab versions are made to order. Send us your D-MAX's year, cab type and tub measurements and we will come back to you with a quote.
