As far as the coach information, that may not be achievable. Unless someone has them, Fleetwood is your source for information.
As far as the chassis portion that is available. If it is a Dodge Chassis, you can get a manual in the site store over at Classic Winnebagos. I also have many of the Dodge chassis wiring diagrams at my website (http://dave78chieftain.zxq.net/
). If it is a Chevy chassis, then you need the Chevy Light duty truck manual set (multi-book set) for the year model of your chassis. One thing you have to remember is that typically a coach Mfg will build this years coach (i.e 1979) on the previous year chassis (i.e 1978). You need to know the chassis year model (Chassis VIN) to acquire the correct chassis book. Chevy bundled the P chassis (MH & bread truck) information in with the C/K pickup information.
