If you have the original Armstrong Bay Breeze air conditioner, I wouldn't necessarily give up on it. I wish that the Internet had been available when I had trouble with my original Armstrong in 1995. At that time, I had only the input from a dealer to go by, and I ended up replacing rather than repairing. Since then, I have learned that the Armstrong utilized commercial components and can rather easily be rebuilt. Even though my new air conditioner was rated 1,500 btu higher than my original Armstrong -- the Armstrong outperformed the new air conditioner in every respect. What I learned is that rather than looking for an RV air conditioning technician, you want to look for a commercial refrigeration technician.
If you decide that you must have a new unit, you have one major decision to make. Do you want a unit that can utilize your Airstream's built-in condesate drain or can you live with condesate draining onto the roof and down the sides? Utilizing the built-in condesate drain, you will have to select an air conditioner that Airstream supports with a condesate collection pan . . . or one of the air conditioners that has a condesate drain feature that can be adapted to your Airstream's built-in drain. When I had my new air conditioner installed I chose to go without the condesate drain, and haven't had a particular problem with that aspect of the purchase . . . I haven't had any problems with staining on my coach's Plasticoat; but on my Argosy that wasn't originally equipped with an air conditioner, the condesate draining on the roof and down the sides results in rust streaks rather rapidly (they do polish out, but it is a headache).
Good luck with your investigation!
