It's beautiful here in Northern California today and my thoughts are on my poor dash air. Should I try the retro-fix or just toss in the towel and buy a Vintage Air kit from Jim K?
I know this has been discussed many times, and I see from searching the forum that some very handy fellows have replaced the entire HVAC dash system (my first preference, but last project choice), enclosed bone-yard van systems to be attractive, or installed manufactured add-on systems.
We are still in the Honeymoon phase with our Palm Beach and want to drive, more then work on, our beauty so I think a total re-work of the dash is unlikely.
I'm half tempted to just run the roof air - is that effective?
What say the net?

Sure, that works. I used to do that before installing my additional
evaporator.
However, it takes about 1 gallon per hour to run your Onan.
So, after about 100 hours you've spent enough to pay for upgrading
your dash air conditioning system.

Well that puts it in perspective! My Palm Beach is a '76 with the
silly Type II A/C duct low on the dash.
If I go wit Jim K's Vintage Air system should I remove that snorkle?

Back to the question at hand about the A/C.
I have a 76 with the snorkel. I re-did everything and did the Clevenger recirculation mod, plus added the Jim K fans by the mirror to move air around. That, and a good curtain seperating the cab from the rest of the coach and it gets... too cold.
I can't say if just adding the vintage air would be cheaper, but it can be fixed and it does all work.
I found that both roof airs blasting did not do the job on a 100 plus degree cross country trip, but the dash air does.
Just what I did.
Good luck.

Neil,
I agree with you that the '76 dash air can be made to work well. When we
first got the coach and I refurbished it, I installed a transparent shower
curtain behind the seats to enclose the cockpit without causing
claustrophobia. After doing the Zay Brand mods to the a/c, we never used
the curtain, even in our S. GA weather and travelling all across the
country. Converting to Duracool improved it even further.
The changes I made when I completely redesigned and rebuilt the HVAC were
not because the a/c didn't work well.
