Perhaps because this is a site of likeminded helpful enthusiasts that help each other out, not a free book store.
If you consider you might like to help others and bring something to the party as well as receive the help you need then head on over to the ‘Introduce yourself’ section and tell us a bit about your truck, Post up some photos, that sort of thing. Oh and use words like Hi, Hello, G’day folks, that sort of thing.
Then once you’ve done that post up a thread about your problem and someone will help you. Downloads are available for long term members who subscribe but other members will help, even with manuals or pages.
