Custom build of a Kenworth C509 as autralian roadtrain

A good source of information that I use is to obtain what are often called "Body Builder Manuals". These are published by the various truck manufacturers and are full of drawings and dimensions of the trucks made by that manufacturer. These manuals are principally used by the makers of aftermarket bodies and equipment that will be mounted on those trucks. The manuals for modern trucks can usually be downloaded for free from the truck manufacturer's web sites. Manuals for older trucks were usually printed in bound books that often can be found for sale on line on sites like e-bay.
