It’s almost as bad as fly fishing – the crazy names Airstreamers come up with for pieces and parts of our beloved trailers. If you were wondering what a “Banana Skin” is, it’s the curved piece that goes around the corners between the side skins and the belly / belly pan area.

As you can see, when your Airstream comes to you with someone else’s battle scars, or invasive surgery scars, you have want to do the patching that accomplishes two important things – keeps the rodent population at bay, and keeps the water from having an easy entry into the bottom of the trailer.

As much as we would like to think we are building our Airstreams in the likeness of our houses, I have come to find that it’s better to think of it as building our trailers to be “super tents” instead. I have spent enough nights on the ground, in a tent, in the rain, in sleet, in snow … that an Airstream is a long way up the chain from the tent days, in my new-found opinion.

We not only put the banana skins back on the trailer, we also:

– gently beat some of the dents out of the leading (front) edge bananas — that came from rocks

– patched the bananas

– cleaned the Airstream trim pieces – BACK and front before riveting them in place

– coated the edge of the “belly board” – that will he holding the new fresh water tank – with epoxy

– riveted all the trim (between the bananas and side / the side and around back) back into place (It’s the lower trim piece

That lower trim piece has several functions, and a certain way I seemed to think made it go back on better.

The turns are where a bent, or protruding trim piece will show most, so that is where I started my rivets – securing the turns, and then coming around to the sides / front / or back flat runs. There were places with significant gaps between the trim and the side of the trailer (not so much along the straight runs). And those places seemed to be caused by the body skin being dented at some time, perhaps during the full monty. So we got back inside and took a soft mallet to actually hammer the skin back out to a natural position that closed the gap. Makes sense.

TRIM YOUR RIVETS

Another thing that makes sense is to trim the rivet if you find them getting too close to a raised edge of the trim piece. As you see in the photographs, just take a pair of metal cutters, and trim the edge that would otherwise keep the rivet from being flush. For whatever reason, be prepared to have two different size rivets along the way as well – and make them the “Medium” length while you’re at it. Those holes can start off different sized, or after 43-years, they can end up different sized … can’t we all?

SEAL THAT EDGE

Sealing the edge of the plywood that goes on the belly of the trailer makes sense because it will be (indirectly) exposed to all the elements we find on the road. Once the plywood is dry – hardened fiberglass resin – I will finish the piece with a thin piece of aluminum or galvanized tin sheet metal to prevent road damage. YOU HAVE TO IMAGINE all the things that will be hitting the bottom of your trailer along the way, and although it’s a thick piece of plywood, that last cladding of the plywood makes it bulletproof.

BE A TRAILER

I try and imagine myself tied to the bottom of the trailer, face down, facing the road. That makes me think about all the things coming at the trailer – rain, rocks, snow, low clearance crossings and all the things we see on major roads these days. Just go with a worst case scenario, and prepare the bottom of your trailer for that – that should do the trick. Cladding, the skins, a good seal, all of these things are what we do to prepare the trailer itself. From there, later on, we prepare the vehicle to minimize what it throws a trailer’s way, but that’s another story for another day!
