Where do I get manuals for a 1996 Wildwood TT?

What I am also looking for is a schematic that shows a picture of each side with arrows saying "water goes in here", "water goes out here", "sewage outlet", "plug for X or Y", how to crank down the awning, explains the "control panel"... like that. I mean I know my TT isnt very complex, but it must have come with some kind of manuals when new ... right? I wonder why people dont drop those into a drawer instead of tossing them out?
