Finding coach serial number on a 1978 Itasca

[78BraveGuy]

Does anyone know where I can find the coach serial number for my '78 Itasca ICP25RB?  I have looked all over and don't see a tag anywhere.

The coach serial number should be in a couple of places. The tag near the driver's seat has the Winnebago VIN and the sheet found is a cupboard or wardrobe cabinet listing all the equipment in the unit has the Winnebago VIN.
