Interior Hardware/Repairs

I have a 73" Land Yacht. I am in the process of reworking it, starting with demolition of the interior cabinetry, plumbing and lower panels. I am going to remove the superstructure next spring and rework the trailer frame and floor.
I know what I am doing at this point and I will take care in bracking the superstructure well.
I have a few discoveries I am baffeled by.
1. I found 2 plastic tubes in between the inner and outer skins that look like drain tubes. They go up towerd the ceiling and down into the floor through the bottom channel/plate of the wall. Anyone know what these are. My fisrt guess was that they were drain tubes for the roof vents.
2. I found an unused 14/2WG romex wire in the circuit breaker panel going up between the inner and outer skins. It was never stripped or tied into the electric panel. What is this for. Are these units set up for AC units? Where does it end?
3. There are some cracks in the rear plastic radius ceiling to wall inner skin. Can this be glued, welded or repaired?
4. I also have two interior plastic window trims for the front left & rightwindows that have a break in it.
Can this too be glued, welded or repaired?
5. The last thing is the window trim at the sink. It is plastic and set up for a window shade. I don't want to reuse it but I need some kind of finish like the other windows. Is there a channel material I can buy to make a new window trim to match the others?
If you have any answers pleaser let me know.

1. That's the drain line for the roof AC.
2. That's the power wiring for the roof AC.
3. Those cracks. if fixed properly, can be painted over, and never be seen again. Typically, those cracks suggest that the trailer was locked up for a long time, and the interior temperature, repeatedly, was sky high.
4. Same as # 3.
5. You will have to fix the galley window trim as it's no longer available.

You didn't ask, but if the trailer was indeed parked for a long time, then part of your "check out before repairs begin" should include checking out the axle rubber rods.

Those are condensate drains for the air conditioner. Even if you do not have air conditioners the factory would have put those in for possible future upgrades.

Again it is for the air conditioner and should end at the roof where an air conditioner can be mounted. The exact location can be obtained from Airstream or the better dealers based on measuring from a reference rib.

I can't help you with the questions about plastic. Perhaps someone else will.

I took my '73 Globetrotter down to the outer skin and had a similar question about the apparent condensate tubes. The one shown in your picture is definitely for a center mounted air conditioner, but I have a second tube (and I assume you do as well), that is up front and ends behind the frond end-cap, approximately where the "control panel" would be, had mine come with one installed. Curious.

I have seen various threads where folks have repaired damage to the plastic interior items using fiberglass from behind, sanded it down, and then painted it with Krylon designed to bond to plastic, but I haven't executed yet. I hear folks refer to these plastic parts as 'thermal-formed", suggesting that you might be able to use plastic welding techniques to repair, but again, haven't confirmed.

My '73 had the control panels' thermometer remote-mounted sensor line armored in the same tube as used for the A/C drain line. The line itself was copper-braid wrapped hollow copper tubing about 1mm thick that exited the belly wrap sheeting streetside front to expose the 2" pencil-sized sensor cylinder to the weather...

Hi there. Just a small suggestion: items in an Airstream are usually identified as being on the curbside or streetside, since these terms are more clear than left and right.

Streetside is the traffic side if you have pulled over while towing, so curbside is therefore the other side.
