The better quality the Van the Lower the payload is a good rule of thumb, there is a balance - Safety should come first but in a business world it does not, too many companies will go for the Cheap option for the sake of 300kg and run an unstable overloaded van, there is a difference between a Legal Payload and a Safe Payload.
For example the Mercedes Sprinter will take 1 ton safely and will keep going and going, its the old story buy cheap buy twice, I am not naming any names here but the cheaper options are just poor quality and although they have a legal load its not a safe load.
Luton Vans:If we start with the Bare Chassis, the manufacturers payload will go from 1500 - 1800kg
Sprinter Above Payload 1585, then you have to take off the weight of the Body, minimum 300kg, if you need tail lift you are down to 1,000kg, on a standard Body Weight your best Payload is going to be around 1200kg, we have now come across the best we have ever seen 1525kg on a Low Loader Vauxhall, Visit this link for more info.
