Planning a weekend away with a rooftop tent, awning or recovery tracks? Start with the load your Cannon can carry, then choose the rack and mounts. A higher-capacity platform does not increase the ute’s approved roof load.
This guide covers the Australian GWM Cannon. Confirm the model year, cab, variant and roof mounting points; do not transfer Cannon Alpha specifications or rack fitment to a standard Cannon.
What is the GWM Cannon roof load rating?
We could not verify a vehicle roof-load figure for the Cannon in the GWM Australia accessories page and brochure reviewed for this guide. That is a gap in the available evidence, rather than confirmation that the roof is rated to 100kg.
Ask GWM for the roof allowance for your exact vehicle, including whether the limit covers the rack’s own weight, off-road use and rooftop tents. Keep the handbook page or written answer with the rack’s fitting instructions.
The GWM Australia Cannon accessories page lists roof rails, crossbars and a roof tray, with compatibility to be confirmed by a dealer. Those listings do not establish a single vehicle roof limit for every Cannon.
| Item | What the figure must cover | Evidence to request |
|---|---|---|
| Vehicle roof | Total permitted roof load and intended use | Handbook or written GWM confirmation for model year and variant |
| Rack and mounting system | Platform or bars, feet, rails and brackets as a complete installed system | Fitting instructions, load definitions and mounting approval |
| Accessory mounts | Tent, awning, carrier and any side or cantilever load | Accessory and bracket instructions |
| Driving conditions | On-road, off-road and stationary use separately | Applicable limits and any exclusions |

Dynamic vs static roof load
Dynamic: while driving
Count the rack and everything carried on it. Braking, cornering and bumps load the mounts; confirm the permitted load for the roads you will use.
Static: while parked
For a rooftop tent, assess the tent, fitted equipment, occupants and bedding against the documented parked-use limits and setup instructions.
Do not multiply a driving limit to invent a static rating. A rack’s parked capacity does not approve the vehicle roof for a tent, and a static rating does not permit that same load while driving.
For corrugated tracks or off-road travel, ask for the applicable rating of both the vehicle and installed rack system. Do not assume a universal reduction percentage or treat slower driving as approval for a heavier load.
How to calculate your roof cargo allowance
First check how each manufacturer defines its rating. A vehicle limit may include the rack, while a rack capacity may describe cargo only. Put the limits on the same basis before comparing them, so you neither overlook the rack’s weight nor subtract it twice.
Weigh the complete installed rack assembly, including feet, rails, brackets and lights. Add tent mounts, awning brackets, recovery-track mounts and any other gear that stays on the roof; a product’s shipping weight is not a verified installed assembly weight.
| Example item | Mass or limit |
|---|---|
| Verified total roof allowance | 80kg |
| Installed rack and brackets | 20kg |
| Remaining cargo allowance | 60kg |
| Tent including mounting hardware | 60kg |
| Remaining allowance for extra roof gear | 0kg |

In this example, adding a 10kg awning would exceed the roof allowance even if the platform could carry more. The tent still needs compatible mounts and separate confirmation for parked use; the sum alone does not approve it.
Roof gear also uses the vehicle’s payload. GWM’s Australian Cannon brochure says to account for load and accessories against gross vehicle mass (GVM). Check the limits for your variant and use measured vehicle and axle masses when assessing a loaded touring or towing setup.
Can a Cannon carry a rooftop tent?
A rooftop tent is an option only when the vehicle, rack, mounts and tent documentation support the proposed setup. Check the two load cases separately before ordering a tent.
Check the drive
- Rack, brackets, tent and travelling gear are within each applicable driving limit.
- The rack and tent mounting arrangement is approved.
- Off-road conditions and fitted height are accounted for.
Check the campsite
- Parked-use approval covers the vehicle and complete rack system.
- The assessment includes occupants, bedding and equipment.
- The tent is set up exactly as its instructions require.
If GWM or the rack supplier cannot confirm the proposed tent setup, choose another mounting arrangement. A tub, tray or canopy system needs its own documented load limits and mounting approval; moving the tent off the cab does not remove payload limits.
Choosing a Cannon roof rack
Compare documented fitment and loading conditions before platform size or price. Factory rails, a bare roof and different cab configurations need the correct mounting kit; the model badge or similar roof dimensions are not enough to establish compatibility.
Genuine GWM system
Start with the Australian accessories catalogue and ask the dealer to identify the approved parts for your vehicle.
- Confirm whether rails, crossbars or a tray are supplied together.
- Request the installed mass and load instructions.
Aftermarket system
Ask for the complete mounting kit and written coverage for your model year, cab and roof configuration.
- Check how dynamic and static capacities were established.
- Confirm off-road and rooftop-tent use separately.
The EVparts4x4 roof rack platform is the relevant product to enquire about for this guide. The listing describes an aluminium platform with integrated LED lights and a bolt-on design. These listing claims still need to be checked against your vehicle and the supplied mounting kit.
Considering an EVparts4x4 roof platform?
Send your model year, variant, cab configuration and photos of the roof mounting points. Ask for the fitted weight, load documentation and approval for your intended accessories.
The listing’s 100kg dynamic / 300kg static claims are rack ratings only. They do not establish a Cannon roof allowance.
Confirm Cannon fitment before orderingView platform options
Browse the GWM Cannon accessories collection for vehicle-specific options. For this load-limit guide, the roof platform is the relevant recommendation; a Tank 300 rack or Cannon Alpha accessory should not be substituted without verified fitment.
Checks before installation and driving
- Confirm the vehicle: model year, exact variant, cab and roof mounting arrangement.
- Obtain the documents: vehicle roof allowance, complete rack instructions and accessory approval.
- Do the load calculation: include installed equipment and apply the correct driving and parked-use limits.
- Check vehicle masses: passengers, fuel, luggage, roof gear and towball load affect remaining capacity.
- Install to instructions: use the specified hardware, seals, torque and inspection schedule.
- Check before travel: secure the load, measure overall height and inspect the rack and restraints during the trip.
Keep heavier gear low where practical, and distribute roof cargo as the mounting instructions require. The National Transport Commission load restraint guide explains load securing and mass limits, with links to state and territory authorities.
Do not guess bolt torque, drill locations or threadlocker requirements. Ask for instructions for the actual rack and mounting kit; a torque figure from another brand’s rack is not transferable.
Integrated lights need a separate wiring and road-use check. Ask the installer to confirm the actual lamp function and the rules for your state or territory; the roof-rack listing alone does not establish lighting approval.
GWM Cannon roof rack FAQ
What is the GWM Cannon roof rack weight limit?
There is no vehicle roof-load figure verified in the GWM Australia sources reviewed for this guide. Obtain the allowance for your exact model year and variant from GWM, then check the rack and accessory limits on a consistent weight basis.
Does the roof rack’s own weight count?
Count the installed rack, feet, rails, brackets and fixed accessories against any vehicle limit that includes all roof-mounted mass. Check how the rack maker defines its cargo rating, so the same weight is not subtracted twice.
Can I put 100kg on a Cannon roof because the rack is rated to 100kg?
Only if the vehicle allowance, complete rack system and accessory mounts all permit the proposed load for the intended use. A 100kg rack claim does not establish the vehicle’s roof limit, and the rack itself may use part of that allowance.
Can a GWM Cannon carry a rooftop tent?
Confirm the exact vehicle and mounting setup first. The travelling load must meet the driving limits, and the occupied tent must have documented approval for parked use from the relevant vehicle, rack and tent suppliers.
Is 300kg static capacity enough for a tent and two people?
That rack rating alone cannot answer the question. Confirm the vehicle roof’s parked-use approval, the mounting system and tent instructions, then account for the rack, tent, occupants, bedding and fitted equipment.
Is the roof load limit different off-road?
It may be. Request the applicable off-road limits and restrictions for both the vehicle and complete rack system, and follow the more restrictive conditions. Do not apply an assumed reduction percentage.
Do Cannon and Cannon Alpha roof racks use the same mounts?
Do not assume they do. Confirm the vehicle model, year, cab and mounting points against the rack’s written fitment information; Cannon Alpha documentation does not establish fitment or a roof-load limit for a standard Cannon.
What torque should I use for Cannon roof rack bolts?
Use the specified torque for the supplied rack, brackets and fasteners. Obtain the fitting instructions before installation; the product listing does not establish a universal bolt torque for Cannon racks.
How long does installation take, and can I add an awning?
Ask for an installation estimate for your vehicle and mounting kit. An awning also needs suitable brackets and approval for its loading arrangement; include the awning and brackets when checking roof mass.
