Thanks for the notes. That's a bit concerning as the bus is scheduled to leave this Sunday heading from CA down I-10 through TX to FLA and then up to New York, and there's going to be a lot of hot areas.

Hopefully I can easily get the dash air fixed, but I need to use the cruise airs to supplement. I'm starting to think roof airs would have been a better choice?

Does anyone know whether mixing R12 and R114 is OK?
