What can a Tank 300 roof carry? Use the allowance and conditions for your own vehicle, then deduct the complete installed rack and roof accessories. Separately check the rack, feet and carrier limits. A per-crossmember claim or a stronger-looking platform does not set the vehicle's roof allowance.
For a rooftop tent, check both travelling weight and separately documented occupied, parked use. Do not calculate a static limit by multiplying a driving figure.
What is the GWM Tank 300 roof load limit?
Use the limit and operating conditions in the handbook supplied for your vehicle. Year, market, powertrain and roof equipment matter when identifying the correct documentation. This guide does not establish one roof rating for every Australian, New Zealand or overseas Tank 300.
Why do 50kg and 35kg both appear?
The GWM Malaysia Tank 300 owner's manual, printed page 49, gives a 50kg maximum and a 35kg maximum during rapid deceleration. It includes the beam and other accessories in the load. These are regional instructions, not confirmation for every Australian VIN.
That wording is not a separate 35kg rating for a particular engine, nor permission to plan on avoiding heavy braking. Ask GWM to clarify the applicable loading conditions before specifying a setup. If your own handbook differs, use its instructions and resolve uncertainty with your dealer.
| Term | What it describes | What to verify |
|---|---|---|
| Vehicle roof allowance | The vehicle's permitted roof load under stated conditions. | Your handbook and any written vehicle-specific clarification. |
| Rack or mounting-kit rating | The accessory system's capacity under its own stated conditions. | Whether the number includes rack mass, which feet it covers and any terrain restrictions. |
| Dynamic load | Loading while the vehicle is moving. | All installed roof equipment and travel cargo, including a closed tent. |
| Static load | Loading while parked, such as an occupied tent. | Separate approval for the vehicle, mounting system, rack and tent configuration. |
A stronger rack does not itself change the vehicle's documented allowance. Do not multiply a driving-load figure by three to invent a parked capacity. A product's structural rating also needs a defined test configuration before it can inform a purchase.
Calculate the weight you can actually carry
Your roof budget starts before you add luggage. Include the platform or bars, feet, brackets, fittings and permanently attached accessories. Roof-mounted loads also count towards the vehicle's overall mass limits; spare roof allowance does not create extra vehicle payload.
Vehicle-side cargo allowance = applicable vehicle roof allowance − complete installed rack system − other roof-mounted accessories.
Then check the rack, feet, brackets and cargo carrier against their own limits. Compare like-for-like figures: a rack's cargo-only rating and a vehicle's total roof allowance have different starting points.
| Item | Example weight |
|---|---|
| Vehicle allowance confirmed for the intended conditions | 50kg |
| Platform | 18kg |
| Feet and mounting hardware | 4kg |
| Accessory brackets | 2kg |
| Awning | 6kg |
| Remaining allowance for additional cargo | 20kg: 50 − 18 − 4 − 2 − 6 |
If the applicable allowance in that example were 35kg, only 5kg would remain. The calculation must use the allowance that actually applies to your vehicle and conditions. Neither example confirms that a tent or any particular carrier is suitable.
The lowest remaining allowance still controls. If the rack or carrier in the same example permits only 15kg of additional cargo, the 20kg vehicle-side calculation does not authorise 20kg. Put each specification on the same cargo-only basis before comparing it. Confirm the complete vehicle's gross and axle mass limits as well.
Request a measured installed weight for the exact configuration you intend to buy. Shipping weight, packaging weight and an unlabelled catalogue weight are not reliable substitutes. Add each component once, including hardware supplied with the tent or awning.
Can a Tank 300 carry a rooftop tent, awning or kayak?
Rooftop tent: make three checks
- Driving weight: include the closed tent, its rails and clamps, rack system and all other roof-mounted gear.
- Mount compatibility: confirm the tent maker's required support spacing, bar profile, fastener access and approved mounting arrangement.
- Parked use: obtain confirmation covering the occupied tent and its load path through the rack, feet and vehicle.
A tent weighing less than 40kg is not automatically suitable. Its clamps and supporting rack still add weight, and a driving calculation does not authorise people to sleep on the roof. Do not treat a tent ladder as a workaround for an unverified vehicle or rack capacity.
Awning: allow for brackets and deployment forces
An awning adds more than its fabric and case. Include its mounting brackets and check which rack members can support them. The rack supplier must also confirm the attachment arrangement for deployment; a vertical cargo rating alone does not establish suitability for an extended awning.
Kayak or roof box: check the carrier as well as the load
Include kayak cradles, roof-box mass and their fittings in your calculation. Check support spacing, attachment compatibility and load restraint. A double sea kayak may fit the available length yet exceed the remaining roof allowance once the carrier is installed.
For Australian load restraint guidance, consult the National Transport Commission's light vehicle guide. It addresses keeping loads secure through braking, cornering and other expected driving forces. Owners elsewhere should check their local transport authority's requirements.
Choose the actual roof platform, recessed rack or ladder
Our two linked listings contain different equipment options. Read the selected option and its contents rather than relying on “cross bars” in a page title or URL. A side ladder and a side-window panel are not roof cargo platforms.
MK Frontier listing: platform and accessory options
| Listing option | Equipment category | Purchase check |
|---|---|---|
| MK Frontier Platform Only | Roof platform option. | Platform dimensions, installed weight and mounting kit. |
| MK Sentry Ladder Only | Side ladder option. | Attachment points and permitted user load. |
| MK Frontier Platform + Sentinel Ladder | Platform and ladder bundle. | Exact bundle contents and combined installation requirements. |
| MK Frontier Platform + Sentry Ladder + Side Window Mecha Net | Platform, ladder and side-window accessory bundle. | Each component's fitment and compatibility. |
| MK Rear Side Window Panel Only | Side-window accessory option. | Not a substitute for a roof platform. |
A platform is worth considering when you need a broad support surface and several accessory positions for touring gear. Confirm the usable deck area and approved attachment points; the presence of slats does not make every position suitable for every load.
Check the MK platform option and fitment
Climbing Ladder listing: two distinct options
The second listing offers a Side Access Ladder Only option and a Recessed Roof Cargo Rack option. Choose the recessed rack when investigating a roof cargo surface. Choose the ladder only when investigating access equipment, with its own mounting and user-load checks.
Check the recessed rack option and fitment
Need access equipment instead? Review the fixed side-ladder option. A ladder does not increase roof carrying capacity. Do not assume these two roof racks should be stacked together or that either listing is simply a pair of crossbars.
What about the supplier's 100kg-per-crossmember statement? Its test conditions are not specified. It is not a dynamic rating for the complete rack, a vehicle allowance or a ladder user-load rating. Do not multiply it by the number of members. The fixed side ladder is non-folding and supplied without a lock; obtain its separate permitted user load before use.
Tank 300 roof rack mounting and installation checks
Do not assume every Tank 300 uses the same factory T-slot installation. GWM Australia's official accessories catalogue lists standard crossbars and a separate Ridge Mount rail system with matched accessories. That distinction matters when identifying mounting hardware.
The mounting system on your vehicle must match the instructions for the exact rack you buy. Confirm whether the kit retains the original rails, replaces them or uses specified body mounting points. “Fits Tank 300” alone does not resolve that question.
Before fitting: six checks in order
- Identify the vehicle. Record market, build year, model year, trim, powertrain and sunroof equipment. Photograph both rails and their attachment areas.
- Match the instructions and kit. Check the selected option, feet, brackets, fasteners and packing list before removing any factory part.
- Confirm the mounting method. Obtain the kit-specific procedure, including whether drilling, rail removal or sealing work is required.
- Check dimensions and clearance. Confirm deck size, mounting spacing, clamp access and clearance around glass, antenna and bodywork.
- Install to the supplied specification. Use the stated fasteners, torque values and sealing or isolation materials. Do not substitute a universal torque figure or add unspecified pads.
- Record the finished setup. Confirm installed mass and overall height, complete the prescribed inspection and follow the manufacturer's recheck schedule.
No-drill fitment must be confirmed for the selected kit and vehicle. It does not automatically establish load approval or a warranty outcome. If instructions or torque values are missing, obtain them before fitting or use a fitter familiar with that exact system.
Sunroof, garage height and touring use
Do not rely on a blanket “full sunroof operation” promise. The regional GWM handbook linked above instructs owners to use the roof luggage rack with the sunroof closed. Follow your own handbook and confirm the rack's physical clearance separately.
Measure the vehicle's actual overall height after fitting, then account for the tallest cargo or accessory before entering a garage. For corrugated roads or off-road travel, obtain the vehicle and rack makers' operating restrictions rather than inventing a percentage reduction.
Inspect attachments and restraints as directed, especially if gear shifts or a new noise develops. A shake test, a quiet drive or someone standing on a platform does not certify its load capacity.
What to confirm before ordering
| Information | Why it changes your decision |
|---|---|
| Vehicle-specific fitment and mounting guide | Confirms the roof interface and work required. |
| Installed mass, including feet and hardware | Lets you calculate the remaining roof allowance. |
| Outer dimensions, usable deck and fitted height | Checks cargo fit, accessory positions and garage clearance. |
| Documented load limits and conditions | Separates driving use, terrain restrictions and any parked-use approval. |
| Selected-option contents and delivered quote | Avoids comparing a ladder-only price with a complete platform bundle. |
For the two listings above, obtain verified installed weights, dimension drawings and applicable load documentation before finalising a load-sensitive setup. Do not use another brand's bar length or forum measurements as specifications for these products.
Once the mounting and weight checks are satisfied, use our Tank 300 roof rack price and complete-quote guide to compare the correct selected options, delivery and fitting costs. This load guide does not rank products by their entry price.
Read catalogue weight and capacity graphics carefully. A weight in a gallery image needs a defined scope: platform alone, complete installed system or shipping package. A load figure also needs stated conditions and the exact tested mounting configuration. Do not use an unverified graphic to approve the vehicle's roof allowance or an occupied tent.
Send the details that make a fitment check useful
Include your country, build year, model year, trim, powertrain, sunroof status, roof-rail photos and selected option. Describe the intended cargo and its weight. For a tent or awning, include the model and mounting requirements.

GWM Tank 300 roof load FAQ
Is the Tank 300 roof load limit always 50kg?
No. Use your vehicle's market-specific handbook and its stated conditions. The linked Malaysia manual gives 50kg and 35kg during rapid deceleration, including accessories. It does not establish one rating for every Australian or overseas Tank 300.
Does a 150kg roof rack let me carry 150kg on my Tank 300?
No. An accessory rating does not increase the vehicle's roof allowance. Check the vehicle, mounting kit and rack limits, what each figure includes, and their operating conditions. Deduct the complete installed system and accessories when calculating cargo allowance.
Can I fit a rooftop tent to a GWM Tank 300?
Only after confirming driving weight, tent-to-rack mounting compatibility and separate approval for occupied, parked use. Include the closed tent, mounting hardware and other roof equipment in the driving calculation. Do not calculate parked capacity by multiplying the driving limit.
Will the same roof rack fit petrol, diesel, hybrid and PHEV models?
Do not assume so. Confirm the selected kit against your market, build year, model year, trim, powertrain, roof rails and sunroof equipment. A broad Tank 300 label is not vehicle-specific fitment confirmation.
Are these Tank 300 roof racks a universal no-drill T-slot installation?
No universal mounting method has been established here. Obtain the selected kit's instructions and confirm whether it retains the factory rails, replaces them or uses specified body mounting points. Confirm drilling, sealing and torque requirements before fitting.
What are the rack dimensions and installed weights?
Obtain measured dimensions and complete installed weights for the selected option, including feet and hardware. This guide does not provide verified figures for the linked kits. Shipping weights and measurements from another brand must not be used as substitutes.
Are both linked products simply pairs of crossbars?
No. The MK listing includes a platform and accessory options. The second listing offers a side ladder or a Recessed Roof Cargo Rack. Check the selected option's contents; a ladder-only or side-window accessory option does not include a roof platform.
Can I carry a kayak and an awning together?
Possibly, but confirm the combined weight, carrier compatibility, support spacing and approved attachment points first. Include the awning brackets and kayak carrier. The awning's deployed mounting requirements also need confirmation; spare vertical load allowance alone is insufficient.
Can I open the sunroof with a rack fitted?
Follow your own handbook and the selected kit's clearance requirements. The regional GWM manual linked in this guide specifies a closed sunroof when using the roof luggage rack. A low-profile appearance does not establish permission to open it.
Does adding a side ladder increase roof capacity?
No. A side ladder is access equipment with its own attachment and user-load requirements. Confirm those requirements before use. Do not assume a ladder is included with every rack option or that it makes an unverified rooftop tent setup acceptable.
Does the 100kg-per-crossmember claim establish the complete rack rating?
No. The supplier does not state the test conditions for that claim. It is not a documented dynamic system limit, a vehicle roof allowance or a ladder user-load rating. Do not add individual-member claims together to calculate capacity.
