Creating an Exterior “Pass Through” Box

When I dry dock in the driveway, I usually run a Cat6 ethernet cable directly from the router for the television rather than rely on wireless signal (wireless sometimes drops out when I’m that far from the router).  I also have a 12v wireless router set up in the Airstream, but I usually only use that when I’m traveling (it allows me to run a physical ethernet line directly from my host’s router, so I don’t suffer from signal drop when I’m parked in their driveway/yard or on the street).  I’ve been passing the ethernet cable through the small window next to the door, but that’s a pretty inelegant solution to something that I do fairly often.  I also don’t like that routing the cord that way will eventually deform the window gasket, not to mention it pinches the cable.

My original thought was to place an outlet box with ethernet and coax ports on the outside of the Airstream, but the more I thought about what the port could be used for, the more it made sense to simply create a “pass through” hole.  Sure, the ethernet and coax ports would look more “pro,” but coax is pretty much obsolete already, and I assume ethernet will be there in the not-to-distant-future, so why not do something a little more future-proof?  Plus, I can think of plenty of other things that I might want to pass through the Airstream wall from inside to out or outside to in (extension cord, gas line for portable grill or heater, 12v power, etc.).

So I started by cutting a heavy duty plastic outlet box down to size (depth) so it could fit snugly in the wall between the inner and outer skins.

Trimming an outlet box to fit between the skins.

I then drilled rivet holes, drilled to mark the corners of the opening on the exterior skin, and then cut a  hole using a 4″ cut-off wheel.

After cutting the hole, I put TremPro 635 on the back of the outlet box to secure and seal it to the inside of the exterior skin, then riveted the box from the outside (so the rivets look good on the exterior).

Finally, I used butyl tape around the outside edge of an aluminum weather-proof outlet face plate, and riveted the plate in place over the outlet hole.

The inside will be finished with another spring loaded, weather-proof face plate, but could also be completed using a keystone face plate for dedicated ethernet, co-ax, etc. ports.  The box is below the deck of the dinette seat, so it won’t be visible, thus I’m just going with the spring-loaded door for more universal use.

Things I Learned on Roadtrip #2

I keep taking The Ghost of Ohio out well before she’s ready.  Some would say I’m a glutton for punishment, but I think you “learn things better” when you experience them first hand.  Traveling with an Airstream that is under renovation, though it’s not the most luxurious situation, contributes greatly to improvements in design, layout, use, and materials.

The first road trip (at least the end of it) was a pretty miserable failure.  My kid will always have fond memories of breaking down in the middle of nowhere and being stranded for a week, and he swears that Worland, WY is his favorite place on the planet, but there’s no denying that the end of that trip (post breakdown and what it led to), was one of the worst experiences of my life …and that’s saying something.

So here I am on the second “case study” road trip.  Just me and my 5-year-old driving from Denver to Northwest Ohio.

Use your tire covers (especially when your Airstream is sitting for extended periods).

Tire blow out.  Likely the result of UV damage (covered-side tires were far less deteriorated).  I quickly learned that it is difficult to find trailer tires while on the road, and most places simply will not put anything but an ST (trailer rated) tire on a rim meant for a trailer (liability).

Luckily we had a good spare, but that also reminded me how important it is to check your spare before you leave on a trip!

Having things fastened down and contained is key.

We don’t have cabinets or permanent seating (with storage) yet, so currently everything is in bins (or loose). Even things that seemed like they would never move or slide were all over the place.  Every time we stopped, it was an adventure (and a pain) getting everything back to where we could make sense of and access our stuff.  If it’s an option, even just screwing a 2×4 to the subfloor to create a rail to keep bins from sliding is a good idea when traveling while you’re under construction.

Space to move around is a major consideration.

While it’s fun figuring out just how tightly you can cram everything into a space (Tetris-ing seems like the most efficient way to organize and store your stuff), using the Airstream with all that stuff crammed in there makes me realize how important negative space really is.  After visiting my parents, we also took on extra cargo that contributed to the issue.  Trying to move around while living became a nightmare.  This is a good lesson to learn and will definitely contribute to future layout design.

Be judicious with your preparations.

I have a problem.  I am waaaay too concerned with making sure I’m “prepared.” And to me, prepared means over-prepared, usually to the detriment of getting on the road in a timely fashion.  I also enjoy figuring out how to make my tool collection most efficient for any and all possible situations, but I’m still taking way too many tools.  Take tools that are good for emergencies and can do double-duty, but don’t waste time, space, and weight with tools for a “project” that you might undertake while on the road.  In fact, make your life so much easier and your trip so much more enjoyable by NOT doing ANY of your resto/reno projects while on the road.

A brake controller is a nice thing to have.

I realize now that I had no brake controller all the way from Denver to Indiana.  On the upside, it means the tow vehicle can handle braking with the Airstream if the controller or trailer brakes fail.  On the downside, it certainly wasn’t ideal as far as safety goes, and I’m sure I need new brake pads now.  Be sure you are familiar with your controller and how it works before you head out on the road, so you aren’t figuring out what things mean and how things work while you’re towing.  My controller looked to me like it was doing its job, but I realize now that it wasn’t hooked up properly.

Hensley Hitch Issues (know how your hitch works and travel with spare parts if you can!)

The safety chains go BETWEEN the leveling bars.  I went back and forth on this when hooking up the trailer, and I should have just taken the time to consult the manual.  It seemed like the chain would be in the way of the bars if “threaded” through the middle, so I laid them on the outside of the leveling bars.  Big mistake.  On the return trip, I actually bent one of the struts to nearly a 90 degree angle.  The struts also pinched and dented the head (the part that holds the ball hitch).

I spent almost a whole day trying to find parts to make the hitch work for the return home, but finally just threw in the towel and ended up rolling with the Airstream attached straight to the ball (Hensley Hitch removed).

Additionally, and even though I actually did take time to think about it and try different routing paths, be sure your trailer electrical connector doesn’t get pinched by the hitch.  My cord was pinched at some point (though I’m still not sure how), cutting several of the wires.  I lost my running lights; luckily the brake and turn signal wires weren’t damaged, and those things continued to function.

Materials and routing are important things to consider.

Aluminum conduit (obviously) conducts heat, and the back of your 3-way fridge gets INSANELY hot!  I had a temporary 12v line run up the wall, and it shifted and lay across the refer cooling coil.  I’m surprised it didn’t melt anything (including the wires inside).  I grabbed the conduit to move it, and it burned me good enough to blister. Idiot.  [update: I have since had a similar issue where the conduit fell across the coil again (not my fault!) and the wires inside did actually melt and blew a fuse]

Pay attention to the message other drivers are trying to convey to you!

While driving, the rear side hatch blew off (not really sure how, most likely didn’t get shut and latched properly).  When someone drives by waiving their arms wildly, sometimes they are just admiring your awesome Airstream.  However, more often than not, they are letting you know that something is flopping around or that you’ve lost something (and hopefully it didn’t hit their vehicle).

The biggest fridge isn’t always the bestest fridge.

I tried out a larger fridge on this trip, and I didn’t have it hooked up to propane.  While it’s nice having that extra space, if you are going for significant amounts of time without being able to power the refrigerator (in my case, being able to plug into 120v), you will have problems keeping things cold.  Not only will the larger fridge lose it’s cool faster than a smaller one, but it also takes longer to get it back to cool.  A smaller fridge is easier to use like a cooler (placing ice packs in it to keep it cool).  Just something to consider when deciding on fridge size.

Carry plenty of hand sanitizer and wet wipes (especially if the plumbing isn’t hooked up yet!).

Even if you have plenty of bottled water or jugs, it isn’t always convenient to haul them outside just to wipe your hands.  Wipes and sanitizer are SO much more convenient when you’re on the go (literally and figuratively).  I have also since learned that a pump container of Gojo (pumice hand cleaner) and a good rag is really nice to have if you are continually working on things covered in grease, diesel exhaust, etc.

There are armadillos in Missouri!  Lots of them.

Unfortunately, the ones we saw were all dead and lying on the side of the road.  My five-year-old and I are also convinced we saw a dead platypus (duck bill and beaver tail, no question!).  Yes, I know they only live in Tasmania and a little bit of Australia’s southern coast, but we saw one (shut up), so it must have escaped from a zoo.

Trucks have all kinds of weird diesel pumps these days.  You are not always allowed to use them.

I actually came across a station that advertised diesel, but would not sell me diesel (because I didn’t have a semi-truck). It was incredibly frustrating, especially when running on fumes.

Costco Interstate Marine/RV Battery

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.

 

Exterior Running Lights

Our Airstream came to us with the exterior running lights already wired (a mixed blessing: they don’t look as cool as I’d like, but I didn’t have to do anything with the lights to drive it home).  Some (not all) of the lights had been replaced with LED, but the housing on those new LED lights doesn’t have a gasket at the base; rather, it looks like it’s missing a gasket around the base of the light.

Evidently this is how they are supposed to look, but I wish it looked a little more integrated.  I’m going to leave them as-is for now (they work and they don’t let water in), but maybe someday I’ll make them a little more “fancy.”
