Original AC for a 72 Overlander?

[Sneakinup]

Does anyone know what the original AC unit for a 72 Overlander was? I suppose they may have used a few different units, but mine is a Duo Therm Luxury Line. I can't tell if it is the original or not. Any help would be great!

The original AC would have been either an Armstrong or Emerson.

Those were the factory and dealer installed types, but dealers normally ordered the unit sans AC and added it at the dealership for the additional profit. So yours may be original, but not what Airstream installed.

From 1964 up to and including 1979, Airstream installed the "Armstrong Airconditioners," exclusively.
