Airstream Electric, Exterior Patches, Screens

Now that we’ve got the big job of the interior shell painted, we’ve moved on to all the dozens of little tidbits that come after that. As winter is approaching, I’m also trying to get other minor exterior things completed before it becomes too cold to complete them effectively.

First up was completing the installation of the waste valves. I had installed these previously but had not completed the exterior panel and extension rods to hold it all in place. When I glued up the ABS pipes a few months back, I noticed that on one side I had made the angle of the valve very slightly downward. Ultimately this required me to put a slight bend on the completed valve extension rod to accommodate it. Frustrating, but it is what it is.

Then I installed all of the interior lights (which are 12V low-voltage) and figured out how to attach the dimmer switches – the wiring for these was a bit different than a typical household switch in that it required me to bring a neutral to the dimmer. I sort of knew this, but didn’t think much of it until I went to connect the switch and had to work through the configuration. The basic difference is that the way a 12V dimmer works requires a neutral (three wire) connection, while a regular 120V dimmer does not (two wire.) Fortunately the place where I have the switch has a neutral for other purposes, so I just used that.

I also used this time to insulate and re-install the wheel well covers. There isn’t a lot of space in these, so I had to cut the insulation in half again to make it fit (so, R-3.75.) Here again, a minor oversight – I replaced the water fill port, and the new one sealed so it needed a separate vent. Aesthetically, I stacked them on top of one another. I didn’t give a second thought at the time to the fact that the vent inlet would now sit about one inch above the inner wheel well cover. Probably isn’t a big deal, but may interfere with a drawer in that instance.

I spent a lot of time thinking about what to do with the hot water system. Originally, there was a 6 gal, propane-fired hot water heater. They still make essentially the same model which I could get for about $450 and it would slip right into the existing cutout. But, I felt there had to be something better. Ultimately, I found that several Airstream folks have been moving towards a unit from Excel that is both vent-free and tankless (on demand.) And then the price of it dropped to $149. Sold! This meant that I could close up the cut-out completely meaning one less opening that can leak.

Up next was work on the screens and electric. Mary and I had some discussions about what the best approach was for the screens. Initially I was gung-ho that I wanted them returned to aluminum (they were painted off-white a the factory.) I did a test of paint removal and…it was painful. It became clear quickly that getting the frames cleaned would be an enormous amount of work and they would not really be that great looking anyways. So I bagged that and we looked at paint colors. Ultimately we decided that we would paint all of the metal trim such as door covers, screen frames, etc, using Rustoleum Hammered spray paint in Brown. This quickly covered all flaws in the metal work and, because it wasn’t aluminum color, it didn’t look like we were trying to make it look like original aluminum (one of those pet peeves we have about design.) The knobs on our window controls got a coating of gloss white after a hit of liquid deglosser, and I glued on new fuzzy seal – Airstream changed to black fuzzy seal the week before I ordered (from gray), but I think the black matches better with our colors anyways. the fuzzy seal goes on the frames where the operating arms pass through to close up the space from bugs.

Finishing the 120V electric wiring meant that I no longer had to run an extension cord through the window to power things, so I was eager to get it done too. As mentioned in a previous post, I saved the 12V wiring but replaced all of the 120V with boat cable (basically, wiring made to withstand more of a beating.) Also, the receptacles previously were “speed boxes” – a relatively cheap unit that allows you to cut back the insulation of a wire, stretch it across some channels, and clip the back onto the front, enclosing the wire and making contact. When completed, the unit itself does not need to go into another wall box. While this is a bit simpler, speed boxes are generally junk. So I upgraded to using blue shallow-depth plastic boxes which are then riveted to the interior and Leviton Decora outlets. Fitting everything in was a challenge in its own right, though. It took a good week of working (among the other projects) to get all of the outlets completed. When completed I plugged in the new city power plug (30A SmartPlug) and put a tester in every outlet. I also checked the function of the polarity light, just to make sure it was working as expected. On the 12V side I added some new receptacles – a standard cigarette lighter adapter in one spot, and three really cool USB charging receptacles with power buttons so they are not vampire draws on the battery system.

Next up is getting all of the rub rail and belt line trim installed on the exterior, and setting up the plumbing and drain lines.

Airstream Interior Painting

Now that the Airstream has been moved down to its regular location, we’re moving on to the next steps, which is any final bits needed to close up the ceiling panel and interior painting.

First, we got some good rain (which we needed)…of course it showed four spots that I still had very small leaks in. One near the replaced picture window (rivet leak), one on the door hinge bolts (runs through the threads), one at the back curb side (unclear initially), and one in the stack windows on the street side.

Ultimately, the leak for the picture window and stack windows were straightforward – hitting it with Captain Tolley’s Creeping Crack Cure a few times sealed up wherever it was leaking. The rear curb side turned out to be a loose screw holding in the awning support bracket – upsized the screw for a tight fit then multi-layered sealed it during re-installation with butyl caulk and Trempro 635. The door hinge bolts were more of an issue. I tried multiple things to stop it – covering the bolt heads, more Captain Tolley’s, etc. Nothing would work. I did not want to take them out because the door works and is square and the bolts are a bit rusty. I could be creating more problems than I am solving. Ultimately my solution was to simply deal with the drip leak. Because it ran alongside the aluminum door edge, I used sheet plastic to encase the area all around and created a run for the water to drip down to the belly pan area, where it will evaporate\drain out. Keeping it off the wood floor so it does not rot is the ultimately goal. Success!

To close up the ceiling I needed to clean up the wiring bundles and complete any items, like the solar panel port, that needed installation. I also had to cut all the holes and prepare the wiring for the LED puck lighting we were installing. This took some time because there are a lot of wires to work with. Ultimately I needed to tuck and zip tie wiring where appropriate, then carefully work insulation into the areas around it. Unlike the original layout, we are also putting the overhead lights on regular switches, and had them in three groups (Front, kitchen\middle, bedroom.) I had pre-ran wires for the switches before we installed the insulation. When that was completed, I spent an evening getting the ceiling panel re-installed, which was a chore in itself. It is also 20 feet long, but it slips into two channels on the ceiling, so it was mostly a task of working it in and not accidentally bending or damaging the channel as you do it.

I took the time to do a tape layout on the floor as well to help us visual where things would land. This allows us to think more about the next steps as we move along too.

Finally, we’re on to painting. Stephen has been asking and looking for ways he could help – helping do the primer coat turned out to be a great way for him to contribute. We did a single coat of Insl-X Aqua Lock Primer Sealer. The interior walls are aluminum covered in a vinyl. Over the years, the glues in them can surface and become tacky – often called “mouse fur.” So the Aqua Lock is a product to prevent that from happening, and give a good base for paint.

Last, we put on a good coat of finish paint. We are using a color that we we use in our house – a historic preservation color known as “Outlands Subtle Taupe.” It’s a relatively neutral light gray. Getting things painted made a huge difference in how the interior looked – gone were all the color variations and markings from the old interior attachments, and now the whole place is a single, unified color.

Up next is electrical installation, repair of the rear bumper and more interior finish bits.

Airstream Interior Skins and Moving

In our previous post, we left with the interior insulation being completed. At this point, we’re now beginning to really put back together all of the various pieces and components that we previously took apart.

The first and biggest part is to get the interior aluminum skins back in and re-attached properly. This starts with the end caps. These are molded plastic parts that fit the complex curves in these areas. This was a multi-person job – my nephew popped over to lend some muscle help to Mary and I so we could get them pushed into place and riveted back up. It was a struggle, but eventually we got it fitted back in tightly and hit (most of) the existing rivet holes. Our choice of insulation might have made this a little more difficult – mineral wool is more dense than fiberglass and while I made sure the batts were flush with the ribs, it’s quite possible that we had to compress them somewhat as we fit things together, meaning more effort on our part.

Hitting those rivet holes brings up a good point – we have been careful while doing disassembly\reassembly to plan out what we can and can’t reuse. Generally if it was metal, it can be cleaned and re-used, and if not it has to be replaced. When it comes to attaching things with rivets, it’s far, far easier to re-use the existing rivet holes. One, it means you are not drilling additional holes into things (leaving other existing holes unfilled) and, two, when attaching the skins and caps back on, hitting the rivet holes help you to know that you got a tight fit that matched the factory without having to do lots of additional measuring and checking.

After the end caps, I steadily worked on installing the panels. The pieces on the ends go on first, and I was able to use the lap markings to make sure I put them on in the correct layered order, which makes them look visually correct (ie, horizontal lines match across the trailer, etc.) These panels are small enough to be a one-person job. Given the new sub flooring that was installed, sometimes I did have to trim the bottom edge of the panels a little for a good fit. There is also a bit of investigate work here – I need to put rivets in to hold the piece up, but some rivet holes are lapped with other pieces that I have yet to put in, so they are left with no rivets until later. This took some time and sometimes I had to remove fresh rivets I put in.

After the panels for the ends are installed, the next step is the long panels running down the sides. You might think that it would be easier to put these panels vertically so they are easier to handle, and it probably is. But Airstream installs them in very long single panels from front to back. I do not know this definitively, but I suspect\assume it has to do with adding structural integrity – the long panels riveted down the length likely add rigidity once attached across multiple ribs. The exterior panels follow the same pattern.

These panels are installed from the bottom up, in three rows on each side. The lowest panel is very straightforward, the middle panel is a mild hassle…but the top panel is an absolute, terrible, no good beast. It fits into a concave curve, is 20 feet long, weighs 100lbs, and wants to flop and bend repeatedly. My nephew came over again to help, along with my brother in law. It took all four of us to do it, and we probably could have used another set of hands still. Getting the top panels up took a lot of effort – we first tried putting them in by attaching the bottom edge and working our way upward, but ultimately could not flex it correctly to hit the rivet holes. Going the reverse direction – pinning the top and working our way down – was more successful. Using this method we got the panels hung and mostly pinned, leaving the lower rivets to be done later by Mary and I. To do those, we had to work rivet by rivet, pushing the panel up into place to get the holes where the panels meet to line up and then line up over the attachment hole in the rib. It was a bear, but it got done.

On the subject of rivets. There are an enormous number of rivets on these interior panels. I bought a bag of 1,000 rivets in bulk…and used them plus at least another 500 or so bought locally in smaller packs. There are a LOT of rivets. Airstream likes to note there are somewhere around 4,000 rivets in the average trailer.

With the panels installed I got prepared for another big step – moving the Airstream from the side of our road into its “regular” home in our backyard. I was a little hesitant to move it around before installing the panels since I knew they added to the rigidity of the unit. A few years ago we built a shed (I really should post “part 2” of that…) and I ran electric to it (50amp) as well, so it offers a great location to park it and offer utility connections. We plan on having the Airstream be used as a guest house for friends when not being used to travel.

The updates here on the blog are actually several weeks behind where I currently am at – will be posting a bit more frequently as I catch up to my current progress.

Up next, paint and interior bits!
