I wanted to install AC in mine also this summer but the wife says were going TO Alaska..I not complaining to loud ...keep us informed ..I think I'd found one made in Graham TX ..ARA ...maybe ...around 900.00
Edited later date:: I was sure hoping several more would chime in here .....I want to see some answers also....something else I've been looking for is a later model that has a surp.set-up on it ..this way I furgired I could get a compressor that was good and could buy the AC set-up short the compressor to save money ...
