Castor Dolly For 30 CWT Truck - Checking the Mathematics

[Grant Bowker]

The problem with tare weight is that it includes both cab and chassis (made by Chevrolet/GM/GMH and body (often made by a separate manufacturer) .
It is easy for the chassis builder to give the weight of their part of the truck, also easy for them to give the gross capacity but less easy for them to give tare which is only known after the body is fitted, often by someone else. That said, there was a period when Ford and Chevrolet did sell complete trucks (dump, stake, platform etc.) and I don't know if the weight tags for those vehicles would have shown tare or if the same blank tags were used for all trucks, complete or not...
