I have looked at a few threads and found a picture of the set up. I am guessing this setup will be hard to find. So i am thinking about making one either with steel and insulating it or maybe fibreglass. Just need to know the most efficient type of evaporator that is out there at the moment. I am interested in this as I have installed a vintage air(mini)in a hz ute and wasn't impressed with its performance in western Qld. So any help is appreciated.20150208_081125_zpsrhtlbeyo.jpg
