1972 C30 camper Special Cab/chassis

[slotdad]

I am looking for information, pictures, whatever for a 72 c-30 camper special. Supposedly GM made a cab and chassis with a camper body on it. Not a bed mounted camper, no bed at all.I recently purchased a cab and chassis, factory air, BB, buckets w/no console, no gas tank behind the seat. After stripping the paint, it appears that at some point someone had repaired the back of the cab where a pass through from camper to cab was.I didn't know if the factory ever did these. I remember seeing some trucks with campers way back when but never cared enough at that time.
