OK this information is from a 1966 Chevrolet camper brochure. These is what the custom camper package included.

3. Custom Chrome

The Custom Camper option was only available on 3/4 ton pick ups and 3/4 ton chassis cab models for 1966. In 1967 with the new body style it was offered on all pick ups and chassis cabs.
All the above options could be had separately except the ID badge.
Hope this helps if you have questions I have almost a complete set of Chevrolet Recreational brochures 1965 to 1984. Thanks Matthew
