Question:
Is this compatible with Airstream Interstate?

Helpful Expert Reply:
It sure is Maurice. The Furrion Variable Speed Chill Cube RV AC w/ Heat Pump & Ceiling Assembly item # FR77TQ will definitely work as a replacement on your 2016 Airstream Interstate motorhome. It requires a dedicated 20 amp breaker which is what your current AC system is powered by.
The Furrion item # FR77TQ includes an air distribution box for ductless setups. The included wireless remote will allow you to control the settings. This system fits the standard cutout size so it'll be a solid upgrade with no compatibility issues.
We also have the Furrion Variable Speed Chill Cube RV AC w/ Heat Pump & Ceiling Assembly item # FR87TQ, which is an identical system it just includes a black AC unit.
What kind of climate do you typically camp in and do you do any boondocking?

How thick is your ceiling? In my experience the Furrion chill cube was designed for ceilings 3 1/2 inches to 6 inches. My camper, the ceiling was only 2 inches, my trailer is aluminum. Yours could be similar. If your ceiling is under 3 1/2 inches, you will need to make an adapter/spacer between the air conditioner and the distribution box. I can tell you both eTrailer and Furrion were not able to offer any assistance (other than to tell me that I’ll need to build my own spacer. I built my own space or using inch and a half box tubing. It turned out super nice. If you ceiling is 3 1/2 inches or thicker, you are good to go. I am super happy with the air conditioner. It runs on a 2500 W generator with no issue and is ridiculously quiet.
