For those who have said how much they can carry there are other weight factors you need to take into consideration with regards to your SWL.
The plate on your vehicle wont have allowed for fuel, a full tank can ne approx 60Kg, air-conditioning (have you got that in your vehicle, it wont be included in your SWL and they are weighty articles), reels 35kG?, battery 10Kg?, toolbox 5Kg?, your workmate 90Kg?, ladders and rack 30Kg?.
Its easy to go over the weight limit without blinking an eye.
