Just a few thoughts on the dash air system on the late (1977-78) coaches. Our system seemed to work, after a fact, but nothing to write home about for sure. If it was much over 90 it wasn't very comfortable and we live in a dry area not plagued with the high humidity many are faced with. Before our last trip we decided to try using a curtain in the track GMC conveniently installed just behind the driver/passenger seats. My expert Blush seamstress wife whipped up a nice insulated custom curtain for that track. The first day out from Albuquerque with temps near 100 wasn't too pleasant especially late afternoon with the western sun making our seating location a real 'fish bowl' . But wait, we had that nice new curtain we hadn't closed behind us. The next day we closed it and headed on west on through Las Vegas and their 'dry heat' 108. I couldn't believe the difference in temperatures up front. With the A/C only having to cool the front of the coach, it did a pretty fair job. I'm not going to claim it's as cool as our car, but certainly acceptable. I guess GMC had a pretty good handle on the problem back in the day.
Something others might want to try for a really small investment.
Oh, BTW, we found some of the smallish hooks GMC used for the curtains already installed on a ribbon which makes the job soo much simpler.
