1975 Winnebago Canadian - Need some details

[Trunkhill1]

So I purchased a Winnebago Canadian travel trailer manufactured in 1975 from the ID plate on the side of the trailer.  Can anyone give me a line on where I could find layout/schematics/owners manual, etc?  I'm going to start pulling the interior apart soon.  Repaint, re-floor, and modernize.  May redo the layout.[/size]Also, anyone ever encounter a 4-bolt rim?  They have Dodge hubcaps on it.  I'll be looking for a spare to put on a bumper mount.
