1965/79 Camper Specials:
1965/72 F100 / 1965/79 F250 / 1967/79 F350.
There is no such thing as an F150 Camper Special.
There are no codes within the VIN or stamped on the Warranty Plate that define a Camper Special.
The only way to tell if a truck is a real Camper Special...or not, is by the taillamp harness.
The taillamp harness on Camper Specials has an extra feed wire/plug. This was used for the pigtailed wire/plug Ford provided for all Camper Specials to be used for camper lights.
Just because a truck has a camper shell or overhead or frame mounted camper, does not mean it's a Camper Special.
Prolly 90% of these trucks with some sort of camper mounted on them were not Camper Specials.
