Chevrolet & GMC Chassis Service and Maintenace Manuals
The P Series chassis was produced in 2 different versions. The motorhome chassis is reffered to as the P32. The stepvan chassis is reffered to as the P42.

Both Chevrolet and GMC produced a P30 Chassis version. As such each one produced seperate documentation for each year. Even though there may be some minor differences between the 2 different manuals they are typically 99% identicle. You can use either version (Chevrolet or GMC) of a given manual to support the chassis. The P/N for each manual is included in the description.
