"Po folk"??? Oh Pleezee!!! you know that the headliner you have is the same as the "high roller" classics!!!

Us middle ground International CCDs and Safari SEs / Flying Clouds are just freezing away watching all our heat leave the trailer in the winter....

Wheel Interested's post #4 shows a classic with the new air box...

It took two tries but I finally got the correct parts from Dometic. The Airstream part numbers are useless when you go directly to a Dometic dealer. I'd highly recommend going through Airstream for your parts.

Parts, tax and shipping totaled $156.

It was an easy process. You just take off the cover and remove the three large bolts holding the inner frame to the outside a/c unit. Then you need to remove a few screws holding the electric box to the ceiling of the trailer and move it within the air conditioner hole because the new air box is not as thick.

The old inner frame used two bolts toward the front of the trailer and one toward the rear. The new inner frame used two front and two rear. That got me worried, but the holes are there. You just have to dig the vulkem out of them. So you connect the new inner frame to the outside a/c unit using all four bolts. The bolts are included in the kit.

Finally you connect the air box to the inner frame. There are only two screws that go into the inner frame. Then there are three more that just screw right into the ceiling using self-tapping screws.

Not only is this upgrade great visually but it's also more functional. Especially if you have someone sleeping on the booth like I do. They finally get some airflow. You can see the small side vent in the photo that directs some air toward the kitchen as well.

So here are the before and after photos and the transformation from 1970s to 2000s.

That does look good! Thanks for the update. Is it any louder/quieter than the original box?

TinLoaf · 08-19-2008, 01:15 PM

I haven't had much of a chance to test it but it was definitely more quiet when you open up the big vent on the bottom and let all the air blow straight down. When you have the air directed out the four vents is about as loud as the old one but it distributes the air much better. I'm very pleased.

As for the marks in the ceiling, the new box definitely has a smaller footprint so dents in the vinyl will show up. In fact there are small scuffs from where the corners rubbed on the aluminum in mine.

Here is the Airstream PN#s and prices: (per my invoice)

690380-10 Air Box/C. Shroud P. White $56.25
690380-11 Adapter - Duct Use w/690380-10 $15:63

Hope this helps if you want to order from Mothership or your dealer.

Hi Kevin

I just called my Airstream dealer here in CA and the part numbers you list don't come up on their "Airstream computer" when they punch in the numbers.

They say they can order directly from Dometic....is the part number 3310700.12 as posted by TinLoaf?

Thanks
Dennis

Hi Steve
What were the final Dometic part numbers?
Thanks
Dennis

TinLoaf · 08-20-2008, 04:07 PM

The correct Dometic part number for the inner air box assembly is 3310742.016. I was charged $110 although I think they over charged me. $110 was the price of the assembly with the built in thermostat and knobs and I don't think they changed it when they finally sent me the correct part. Without all the electronics I'm pretty sure it should have been around $60.

If you have the Penguin heat pump you will need the air duct adaptor - 3311109.00. It was $25.

I'll try these numbers with my dealer tomorrow.

Got a 2008 Classic 25fb and I may want to upgrade the air distribution box since the base on my current old style box has developed a stress crack midpoint over the ducts. Probably due to the stress of the slight roof curve. Where is the best source for the parts so I'm confident I'll get the right parts.

Thanks

Kelvin,
I'm doing this right now. The parts are being delivered today. I found the best prices on eBay from different sellers. The duct adapter kit was $19.95 total and the ceiling shroud was $95.50 total.

KJRitchie · 06-16-2014, 01:35 PM

Can you post some photos of the install and the part numbers you used to order. I did a temporary fix on my cracked shroud. As someone said before if you squeeze together the shroud sides the crack pretty much disappears. I cut some sheet styrene (purchased from a hobby store in the model train section used for making buildings) strips and while I had my wife squeeze together the shroud sides to close the crack I applied some thick CA glue on crack on the inside of the shroud and pressed a strip of sytrene sheet on the glue covering the crack. Unless you look very close you can barely see the crack. Did this to both sides.

Got it in

You can still see the indent that the old one left, but hopefully that will go away some. This was way more than an hours work. The instructions are useless. Yours may be less trouble as it is a newer unit. Mine is a 2004, 1500 heat pump unit. The duct adapter is included with this, you do not need to order one like I did

The hardest part was getting the duct adapter to fit and stay in place. I ended up enlarging the duct adapter opening and used 2 metal screws to hold it in place (the 2 sided tape that came on it would not hold) . You only need to order this:
Dometic 3310742.014 ADB RV Wall Thermostat Polar White.

KJRitchie · 06-19-2014, 09:42 AM

Thanks for the photo. I doubt the ceiling imprints will go away. I repositioned the chandellier light over our dinette and the circular imprint is still there after a year in hot and cold. Luckily I just shifted the fixture about 1/2" so unless you look for it you don't notice. I'm not sure if applying heat or cold would cause the vinyl to reset.

I don't think Dometic changed much between 2004 and 2008 since mine is a Penguin 1st generation also so I bet this would work on my 2008.

How do you find the airflow now and has it improved the noise?

Kelvin

RLS · 06-19-2014, 05:09 PM

This photo shows the left duct adapter enlarged compared to the right one that they use. This definitely helped with more air volume compared to what was used on the original one

.
The next photo shows how this also has the side vents. Air distribution is much better with side , bottom and end vents. So yes, there is more air being distributed. Now for sound level? I wish but do not think so

rodsterinfl · 06-19-2014, 05:13 PM

Yes, I changed mine out over year ago when we took our first week trip in the summer. The air blowing on people at night was too much as we were all sleeping on both ends. Blowing the air down and to the sides in the galley area really makes a difference.

I do not remember using a duct adapter.
