Designing a support system for an Airstream is not an easy task. The ribs are spaced quite a distance for the intended load. I have revised the "new" plan several times. I'm designing the frame work to easily carry a Coleman AC unit. All the parts are special and one of a kind. Because of the location on the roof, my design will try to make some or most of the weight be supported by the wall or devider sections near. Yep, the wall supports must also be reinforced. The electrical is pretty straight forward except the new unit must be modified to be controlled by the t-stat. Making the Airstream factory drain may be a challenge too. Now isn't this fun??

The center section of the ceiling is called a multi-dome. It is easily removed. After removal, horizontal stringers to support the weight of a new style Air Conditioner can easily be added. These stringers must be in one piece, and be riveted to both the fore and aft main bows, as well as to the ceiling and roof, as the interior and exterior shell are both "load bearing."
Can you post a photo of the front side of the switch that is shown on this thread?
My 27' 71 Overlander has an Armstrong AC and I think that the contro switch has been replaced with a non OEM switch.
The faceplate indicates that there are about 6 to 8 positions. Low Fan, High Fan, Low Cool, High cool, Heat etc...I cannot look it it right now. I am out of town.
My switch has only four positions and it has to be in the Heat positin to cool, Hmmmm?
Anyway I have benn trying to find the correct switch and I am curios abou the one in the photo. Does your original AC have more than four positions on the switch and if so, how many positions does it have?
Do you want to sell or pass on the old switch if you are replacing with a new AC?
Thanks,
Thanks for the Pics Frank,
Apparently I have a different model and a different switch.
I will call my wife and get the details right away,
I am in hot pursuit of correcting this issue with the OEM switch.

Ahah! I have been chasing my tail. The drawbacks of traveling and trying to work on ones AS. I called my wife and had her look at the AC. It is a Coleman SuperMach. It has nine positions on the control switch faceplate. As I metioned the switch only has four positions. I am going to start looking for Coleman post' now.
sorry to drag you along on my tail chase
