AC Replacement 66 Overlander

[mark m]

Cool, So two ladders and a walk board just for extra support. Any thoughts for the heater replacement?

The original AC became a part of the roof.

It "DID NOT" have any framing built in.

When you install a new Ac, you will have to install a couple of "stringers" and cross members between those two stringers.

If not, the new AC will cave in the roof, when you hit the first bump.

I'm really confused, but that's not new, as my husband can tell you! We bought a 15,000 btu Carrier Low Profile unit to replace the original Armstrong a/c on our '78 Tradewind. After reading all the posts, I thought that the new a/c would require 14" x 14" framing built out of aluminum channel to go between the inner and outer skins. I actually sent links from Air Forums to the service center to explain what I was talking about. The lady at the service center then told me that no new framing was needed. Did Airstream include the framing on 1978 models? Andy and anyone else who sees this, would you mind chiming in? I want to make sure that this is installation is done correctly. I certainly don't want my a/c winding up on the floor, nor do I want mold in the roof.


Thanks,
Brenda Heinold

Have you installed your A/C yet? If not check out these two threads for installation of the ribs/stringers between the skins.

Suburban furnace, Atwood water heater, either 6 or 10 gallon, and either gas or electronic ignition, Jabsco water pumps.

There are cheaper versions of the above.

I suggested top brands that offer top perfomance over many years.

Thanks Andy, Do you know what model number for the suburban will fit in? Does any water heater fit?

Mark.

Suburban NT-s0 SP is a popular model.

But, you may have to be a little creative to install it in a 43 year old trailer. Attaching it to the duct work, is the hardest part.

You will need an adapter plate for the water heater, even if you us a 10 gallon version, since the outer dimensions are much smaller than what you have now. It's not a big deal to install the plate with sealer and Olympic rivets, and then cut a hole for the new water heater.

I am on vacation, so I cannot give you any dimensions until I return on the 22nd.

Richard, I have heard about the carrier, I think i will go with that.

hey tchannel, I will let you know when i get the old unit off. I do not know what model it is.

Hey guys, Does the hole for the new unit need to be exactly 14"x14", or can i fudge a little?
