Location in ceiling for AC in a 67?

[Silverwanabe]

Hi Everyone,

Where exactly do you cut the 14x14 hole for an AC in a unit?

This unit has no ac.

67 Overlander side double.

AS told me yesterday the wire is 124 inches from the first bow/rib.
Is that the exact location for the AC?
I have seen other 67's and the ac unit is over the axles in the bedroom.

I do know, the ac is not mounted in a ceiling vent
I will have to beef up the ceiling for support.

I am leaning towards the Carrier 15k unit with a heat strip.

Thanks for your help in advance

That dimension is on the "nose."

Make sure you beef up the roof before you install any AC at that location.

I have cut the hole in the ceiling for the new AC.
(I have not trimmed it exactly 14 x14 yet)

There are two wires located in this area.
Which one do I use??
Why 2 wires?
Both are Kaiser Aluminum .
One has a bigger diameter and there is one like it in the trunk area not connected the the breaker box.

Also, there are two ribs running parallel to the new hole in the ceiling, a few inches from each side, running fore and aft.

I am assuming this is where the AC support frame ties into the structure for support.

Suggestions are welcomed.

Enclosed are 4 pics.

The AC's that Airstream used in 1967, did not require roof supports, since it became part of the roof.

Adding a new AC today, will require 2 horizontal stringers that tie into the fore and aft main bows. Additionall, two other sections of supprts must be added between the 2 stringers, making the 14 x 14 inch hole in the roof secure. It not done that way, a new AC will cave the roof in.

The largest wire is for the power to the AC. It terminates near the breaker panel, and must be wired into that panel, using a separate circuit breaker rated at 20 amps, no more and no less.

The smaller wire, is for the thermostat wires. The other end of that wire should be in the rooflocker on the road side, and behind the bulkhead.

The 2 stringers I mentioned must be added in addition to the two that you see.
