Just some links I’ve found useful…
I am always baffled when I see Airstream interiors with a couch or two chairs under the panoramic window. What a waste of space! The dinette with seating that wraps around a table is obviously the way to go, so one can maximize on seating, have a decent table at which to eat, and also to collapse into an extra bed. Not to mention all the extra storage in the dinette bench seats!
However, I can’t believe how hard it is to find a decent telescoping base for a dinette table!
Most of the choices come from yacht outfitters, and are thus astronomically priced. The few “RV Specific” bases I have found seem to be poorly reviewed as a result of being poorly constructed (weak materials that lead to wobbling and bending). The two companies that come up most often in a search for RV dinette/table bases are Springfield and Garelick. The products from each company look to be fairly similar, but for what it’s worth, the reviews for the Springfield products are much better than those for the Garelick. This means that either the Springfield bases are a superior product, or Springfield has a better social media and internet team.
Since I’m rebuilding from scratch, this wouldn’t be as much of an issue for me, but it definitely does lock you in to the position you originally install (since it telescopes through a permanent hole in the floor, and sticks out into the belly pan area). I think most people will want a surface mount base, and since there isn’t much difference in availability between surface mount and through-deck, I’m just going to stick with surface mount (which is ultimately an easier install anyway).
The surface mount, telescoping pedestal base that seems most solid, best reviewed, and within price range (though still more expensive than I would expect at around $400) is the Springfield 12″ – 28″ Anodized Air-Powered 3-Stage Table Pedestal. There are three slight variations that included differences in lift range and finish materials, but this one has the lowest price (by about 40 bucks) and the highest reviews. It’s also conspicuously similar to the base pictured in the Airstream brochure photo above, so there’s that.
Another interesting and slightly less expensive (around $250) option from Springfield is the lever lift Springfield Marine 1660203 Polished Aluminum 12-25 Inch Adjustable Hinged Boat Table Pedestal, though it’s quite a bit bulkier, and I see lots of opportunity for pinched (or even lost!) fingers.
Penguine Eng LTD looks great and has a lot of selection, but it’s in Great Britain, so there’s VAT and shipping on top of already “luxury” pricing.
Motorized is great for the “wow” factor, but my philosophy is, “The more you motorize things, the more opportunity there is for mechanical failure.” If you can make something function well without sacrificing ease of use, that is the way to go. Can gas/air systems fail? Of course. Will they fail as often as something that uses electricity, plastic gears, wires and solder, etc.? Nope. If gas/air makes it easy to lift/lower a table (vs. a completely manual system which is difficult to slide up and down and lock in place) while minimizing the chance of mechanical failure, then for me, a gas/air lift telescoping base is the superior choice.

I had quite a few questions to answer before deciding how I would insulate our Airstream. I was lucky enough to get our trailer with the interior already removed, which means I didn’t have to deal with the toxic mess of removing the original fiberglass batt, which is almost ALWAYS infested with rodents, their homes and tunnels, and their droppings in these older Airstreams. Not only that, but the batt is usually wet and filled with mold, and often still glued to the skins and difficult to remove completely.
I knew I wouldn’t be reinstalling fiberglass (it’s AWFUL to work with, and doesn’t hold up as well as a lot of the newer alternatives), but I wasn’t certain as to which option would be best for us. My initial thoughts revolved around using Spray Foam, but I did a lot of research and eventually decided to go a different route.
Here were my areas of concern when thinking about insulation for the Airstream:
As mentioned, Spray Foam was my initial choice for insulating the Airstream. The thought of using a very light product that not only gets into EVERY nook and cranny, but also seals things up and ads structural integrity to the trailer just seemed like a no brainer. However, there were some issues I uncovered that eventually caused me to go in another direction.
Spray Foam Cons (for my Airstream):
A lot of people on the Airstream forums expressed concerns with Spray Foam breaking down into “fine powder” because of road vibration, but I think there are enough examples of places it has been used successfully (factory installed in various Argosy and other brand trailers, most modern refrigerated trucks, people who’ve done it themselves, etc.), to eradicate those concerns. Perhaps the cheap “canned foam” options from big box stores would break down, but I think commercial products will hold up to the rigors of the road.
Bear in mind, if you go the Spray Foam route, you need to make sure the product is closed-cell foam (not open cell, like the canned stuff at the big box stores, which will take on and retain moisture).
Also, spray foam seams like a bad idea for the chassis (insulating the underside), as it will retain water between the floor and the foam and thus contribute to floor rot, not to mention it prevents access to all the stuff down there that might need regular access (wiring, plumbing, holding tanks, etc.).
If the state of the original fiberglass or rockwool that you see when removing your panels isn’t enough to assure you that there are now better choices, here are some other reasons fiberglass batt sucks:
A lot of people go with Reflectix or Prodex. And though the two products look similar, they are actually quite different. Reflectix is foil-faced bubble wrap (yes, that bubble wrap). It’s fairly worthless. Prodex is actually foil faced closed-cell polyethylene foam, which has a greater R value than bubble wrap (meaning a “real” R value).
Reflectix is more readily available; you can pick it up at your local big box store, but it doesn’t do much for you. Your Airstream is already made of a reflective material (shiny aluminum!), and the bubble wrap doesn’t really insulate anything (very minimal air contained within the thin layer of “bubble”).
Prodex must be ordered, it’s relatively expensive, and I’ve read in quite a few places about Prodex delaminating (the layers coming apart). 700 square ft. (two, 24 inch wide x 175 ft. rolls) is around $250. Most variations on size still come in around $250 for 700 sq. ft., so the product is around $2.80/sq. ft. (right around the same price as Rigid PIC Panels).
Many people will point out Prodex’s claim of an R-16 rating, but that rating comes with some pretty unattainable parameters (at least in an Airstream). From their product spec sheet:
Parameters of test: 24-inch on center 2″ x 6″ wood assembly. Roof application. Test method ASTM 1116. Airspace of 2.64 inch on each side of product. Heat-flow direction down. Interior side of product exposed.
To get an R-16 rating from a 3/16″ sheet of Prodex, you need more than two-and-a-half inches of air space on either side of the material, PLUS air flow (venting). I can’t seem to find an R value for the product without the air space on either side.
Prodex is extremely easy to install and they claim it is self-sealing, so that’s great, but cost and availability (and the fact that the Airstream doesn’t have 5 inch walls) knocked it out of the running for me.
There are several types of “rigid panel” foam products.
Polyisocyanurate (PIC) panels are rigid foam panels that are quite water resistant and sport an R value of 6.5 per one inch of thickness.
Thermasheath Rmax is sold in 4’x8′ sheets and is readily available at Home Depot (Lowe’s does not carry any PIC panels, only extruded poly and Styrofoam). At the time of this posting, here in Colorado a 1/2″ thick panel (R 3.2) is $11.97, a 1″ thick panel (R 6.5) is $16.35, and a 2″ thick (R 13.1) panel is $28.85. Obviously the 2″ thick product is too thick for the Airstream wall cavity, so you’ll either need to go with the 1″ thick product or multiple layers of the 1/2″.
The 1″ thick panels will need to be scored to follow the contour of the Airstream walls, and the scores then need to be resealed with foil tape to maintain the moisture/radiant barrier of the foil facing. The 1/2″ panels will actually bend enough to follow the contour of an Airstream (though not the compound curves of the end caps) without scoring the backside of the panel. If cost is not an issue (the half inch panels are more expensive in regard to total volume), multiple layers of 1/2″ panels are easiest to install since they don’t need to be scored. And in the grand scheme of things, the extra $8 per 1 inch thickness in a 4’x8′ panel is probably well-worth the extra cost in saved time and the fact that there are no voids from scoring and bending like the ones that will be created in the 1″ panels.
An added advantage of both rigid panels and foil faced flexible foam is you can run wires in the voids.
FWIW, I’ve not heard of anyone using “blown-in” cellulose or recycled denim, but I would think potential moisture penetration would make that a bad choice, as well as major settling of the material from the motion and vibration of the trailer.
Finally, something to consider is the thermal bridge… anywhere things “touch” from outside to inside will conduct heat/cold. Insulation can help mitigate this effect between exterior skin and interior skin, but the major problem area is the ribs, which touch both the exterior skin and interior skin, and are made from highly conductive aluminum!
I tried looking in to Aerogel/Thermagel for the Thermal Bridge. Specifically I e-mailed, called, and even snail-mailed Aspen Aerogels in Massachusetts, but I never received a response. I assume this is because I’m “small beans,” and they deal with only multi-million dollar outfits. Considering they seem to be marketing mostly to the oil industry, I am almost certain that Aerogel is cost prohibitive. I have a cousin in green tech and solar who let me know that Aerogel in it’s original form is pretty hard to work with. It was described to me as tapioca-like goo inside a thin wrapper. I would think punching a bunch of rivets through a bag full of pudding wouldn’t work so well.
I have wondered about using neoprene, some left over EPDM rubber I have from the roof on my studio, or even just the blue role of closed-cell poly material that you use between a house’s framing sill plate and the concrete foundation when building a house (i.e. something like Dow Weathermate Polystyrene which is readily available at Lowe’s/Home Depot). I’m not sure if such a thin layer of material would really help prevent heat transfer at the ribs. And even though it’s thin, I’m wondering if it would be a problem (an extra layer of material) between the ribs and skin.
I am starting to think about my battery set up. There are a lot of things to think about (absorbent glass mat vs. other materials, amp hours, 12v vs. 6v, etc.), but it’s hard not to think I might just start with a $79 12V Marine/RV Battery from Costco. The cost just can’t be beat and that battery should be 120ah (other deep cycle batteries in that range go for at least $200). I certainly don’t have $1,800 for a multi-6V Trojan set up right now, so why not just spent eighty bucks to “get by” for a while?
You’re not supposed to use “starting” batteries for powering things in your Airstream (you should be using batteries specifically for “deep cycle” use), but for this price, I can’t imagine not going this route, at least for a while. And I believe these are actually engineered for both deep cycle and cranking/starting, so I should be fine.
I know I have lots more to learn about batteries, etc. and I will be doing a lot of research before selecting and installing all the components of my solar array, but for the time being, it just seems like this battery can’t be beat for the price.
I’ve been thinking about using a utility sink (often referred to as a “slop sink” or “mop sink”) for our Airstream’s shower pan. I was at an architectural salvage place last week, and they had a high-end, black kitchen sink. PERFECT. It looks cool. It’s very sturdy. And it’s a single basin with a kind of “step” for dishes that will now be an actual step!
There are two holes (faucet and soap dispenser) that will either get plugged, or maybe I’ll actually run copper pipe through the holes as part of the shower design.
This “designer” sink obviously looks waaaay better than a plastic slop sink, even though it weighs a bit more (though, that comes with being much more durable than thin plastic). I think having a shallower sink (vs. a utility sink) will be better too. It’s still deep enough for a kid to take a bath, but it won’t be such a pain to climb in.
This “Master To Do List” might be a stupid idea (depressing to look at in a couple of years, when I still haven’t installed a sink!), but it’ll help me keep track of ideas and maybe link to the posts covering these topics.
This is some of the fun stuff we’ll need to buy (not necessarily a “to do” list, just some of the things that will make this Airstream extra cool).
So the first step in laying out a new floor plan is creating a template to sketch out ideas.
I searched online for a while, but ended up making a template out of the original manual’s layout and a piece of graph paper. Here it is if you want to download it (click image for hi-rez PDF):
I removed everything (beds, bathroom, kitchen, etc.) except what might be kept, like the battery compartment and water heater location. I may end up changing those too, but I decided to leave them on the grid.
Scale is one square to 6″.
