What a 2,500kg roof rating actually means

Bushtech tests the canopy roof to 2,500 kg. That figure comes off our own product page and it is a static test, which means the load sits still on the structure while it is measured. It tells you the roof is not going to fold under weight. It does not tell you what you may legally or safely carry on a moving vehicle.

Static and dynamic are two different numbers

Our tray canopy page quotes a 400 kg dynamic load rating. That is not a contradiction of the 2,500 kg figure. It is a different test. Dynamic means the load is moving with the vehicle, with the shock, twist and braking forces that come with a corrugated road. If you are working out what to put on your roof for a trip, the dynamic figure is the one that governs, not the static one.

Your vehicle has its own rating and it is lower

Every ute has a roof load limit set by the manufacturer, and on most double cabs it sits between 60 kg and 100 kg. That limit applies to the vehicle, not to the canopy. Fitting a canopy rated far higher does not raise it. Whichever number is lowest is the one you have to work to, and it is almost always the vehicle.

Find yours in the owner's manual or on the compliance plate. Do not take it from a forum post about the same model, because manufacturers change these figures between model years and between markets.

Where the weight sits matters as much as the weight

Load on the roof sits high, which raises the centre of gravity and changes how the vehicle behaves before it changes anything else. A roof top tent, a spare wheel and an awning add up quickly. Anything heavy that can go inside the canopy instead of on top of it should.

What to do with all this

Work to the lowest of the three numbers: your vehicle's roof rating, the canopy's dynamic rating, and what your rack or rails are rated for. Weigh the setup if you can. A public weighbridge costs very little and it is the only way to know rather than estimate.
