Step 6: Lets install this puppy, but first the Cabinets!

There was a hiatus between dry fitting, hole cutting and the actual installation of the water heater. There was some cabinet work that needed doing before we could complete the heater installation. Our Master Plan involved ripping out all the old base and tall cabinets and replacing them with Ikea cabinets. The benefits included zippy interior fittings along with instant doors with the proper design aesthetic.  Besides, they look amazing in our Ikea kitchen.  What’s not to love?   Wee problem though, Ikea kitchens are square and Airstreams are roundy. Our good friend John introduced us to the perfect tool to fit a square cabinet into a round Airstream.

The Compass

You remember, your old friend from third grade. Well, it turns out that you can trace a wonderful curve on a slab of Ikea press board, trot that press board over to your handy Jig saw (our Brand of Choice is Bosch) and et voila an Airstream-fitted cabinet side.  Now, the tedious part is to do this properly, you must have your tired and irritated helper hold the cabinet side perfectly in place, while you traipse back and forth, cut a curve, fit that cut against the trailer side and cabinet base (held perfectly in place- helper irritated, tired and now hungry), draw a new line for a better fit….repeat.  You repeat this until the fit is perfect or your helper smacks you on the head and demands a beer.

In reality each tall cabinet took roughly a day to fit. This is also where you discover the concept of Good Enough.  What is Good Enough for me might be clearly a Crappy Job for your helper, or vice versa. Ahhh, the opportunities for neighborhood entertainment are endless. Especially when you do this work in the front yard and your helper is your spouse.

Below is a picture of the cabient slot in the trailer.  We have dry fitted the other cabinets and the new bathroom.  We had not cut any holes yet, but you can see where the hole will be cut.  Dry fitting the base cabinets is extremely easy with the compass. It is also a one woman job.  This alone ensures that the next trailer I do will not have any tall cabinets.


Above you can see the cabinet, now dryfitted and attached to the adjacent short base cabinet with a clamp. You can see the curves that we cut in the Ikea tall cabinet.

Pretty nifty for a tool you used last in third grade!

Step 5: Dry fit the mutant heater and cut the new hole (gulp)

Each of these sets of steps occurred over a weekend. So, each Saturday morning Chris and I sat at the island in our kitchen and planned the weekend’s work. The “Cut the Hole in Trailer” Saturday morning mission brief went something like this…

Leslie “We need to cut the hole in the trailer for the water heater…”
Chris ” OK, where?”
Leslie ” I thought you knew where!”
Chris ” Me!! I thought you had all the plans!!”
Leslie ” I have the visually appealing design plans..you have the rip open the side of the trailer plans.”

Now I admit to some hyperbole here, but I can say that cutting a 12″ x 14″ hole in the side of my perfect vintage trailer was, well breathtaking.

So I left.  I left the kitchen, block, town.  I figured three hours would just about do it.  I went to Ikea and then to Trader Joe’s with a brief stop at Target to check out the latest from Isaac Mizrahi.

When I returned, Chris had cut a perfect hole and was well on his way to dry fitting the water heater.

“What, and you didn’t wait for me to see how you did it?” He’s right, you know he really can’t win.


To hear him tell it, was pretty simple. We were replacing nearly all the interior cabinets with Ikea cabinetry. All of those cabinets, including the one that would hold the heater, were assembled and dry-fitted. So the dead simple approach was to fit the heater inside the dry-fitted cabinet and draw on the interior around the edge of the cabinet. When he removed the cabinet, the outline was left on the wall. He then just cut from the inside out following the line he had drawn. Tools used? Mostly a Dremel with a cut-off wheel and metal snips

Above., left looks from the inside of the trailer out. Above, right, the outside of the trailer in.

We have found that the aluminum skin on our trailer is soft enough that this makes for a simple and controllable cutting. I would not use anything more powerful than the Dremel.  A a standard sized cutoff wheel on a grinder is just too aggressive. It cuts through the thin aluminum like butter.

One interesting note on both of the pictures, you can see the U-Channel that the aluminum shell is attached to.
