Does anyone know when or if aluminum AC wiring was abandoned in the construction of all Airstream campers? I know that aluminum was used in the late 60s but I do not know if it was abandoned.
I know that copper was in shortage in the late 60s and early 70s up until about 1976. This drove the housing industry into the use of aluminum wiring for homes and the camper trades did likewise. Because the current capacity of aluminum is less than copper, the wire size for aluminum required a larger #10 instead of #12 copper.
I just wanted to know when Airstream dropped the use of aluminum AC wiring.
