Flamingo Fleetwood 1962 schematics needed

Where can I get schematics for a 1962 Fleetwood Flamingo single wide mobile home? My husband and I are doing work on the roof/kitchen area and would like to know dimensions and original materials used (if possible), to determine best course for repairs. Owner has had several licensed contractors perform repairs and all have been done in a shoddy manner.
