Good to see another vintage Trade Wind. I have a 1968
, made in Jackson Center. I had to replace the bath floor, for starters, and my check list looks a lot like yours. For replacing the bath floor, I experimented with a new product, Nyloboard, not saying that's the best choice for everybody, but I wanted to give it a try. It's pretty much guaranteed to outlive the next forty years, at least where contact with water is concerned.
Other ways to maximize the life of the plywood you might be using to replace your bath floor would be to treat the edges and maybe even the whole piece with a marine finish to seal the wood. There are some threads that recommend that kind of treatment.
On the bath removal, I heard that Airstream interiors started with the installation of the rear end cap and bath fixtures and worked forward. It is hard, hard, hard to get those fixtures out in one piece. And, when you start taking the interior skins out to de-pest your insulation, there are many hidden rivets that will test your patience and make you lose whatever religion you might have. Don't be surprised if you end up just clearing the whole thing down to practically nothing and starting over.
By the way, I found the replacement back bath end piece of floor to be exactly the width of an 8x4 board, and all but the curved corners and just a few inches on the 8' length. I guess a 24' trailer might mean 6 standard sized plywood sections, with the necessary cut-outs for the wheel wells and holes for the wiring and plumbing and so forth. I have seen recommendations of using cardboard for your templates for the floor. Maybe that works for the first run on starting a pattern or template, but I was very pleased with someone's recommendation to use luaun 1/8" thick. It held up under some rain and could take some tacking with temporary screws while I worked out the curves of the back end and got all of those channels and skins back together. The cost was more than a free fridge box, but the durability has been worth it. I have since used the same template to start plans for a new arrangement for the bath and main bedroom. I plan to keep using luaun for templates to get placement of cabinets, new arrangements for fixtures, etc.
For the black tank on mine, the galvanized case holding the black tank and insulation was totally wasted (pun intended). I got a stainless steel case made to hold the insulation and the black tank. It might seem like overkill for a tank that will be covered over with the aluminum belly pan, but I figure that's something I'll never want to mess with again, if I can help it.
I'm interested in how much changed on the interior from 68 to 70. Changes also on the windows, the control center, the light fixtures, the bath, -- lots of changes. It looks like you might have the center gaucho that I have in the 68, but maybe not the front twins? The center gaucho might have had some kind of hinged board that lifted and lowered to make the sofa/bed big enough for two (?). I found out recently that the wall pad shown in your pictures would come in real handy in cold weather, but I'm going to move the bedroom, anyway, but maybe that edging of quilted material against the inner skin will prevent some cold contact with a different kind of skin.
I think maybe the 68 was the last year of the era under the Wally Byam influence. The fresh water tank under the deck is a neat innovation. Glad you could save that tank. Wish I had one!
I have lots of sympathy/excitement for your project. It will be fun when you get to a point where you can start towing it to some parks and enjoy it for camping and visiting friends.
I need to replace axles, also, but can't resist towing around to local parks on beautiful weekends and enjoying the camping. I went ahead and got the tires replaced, bearings, brakes, and had a trailer shop check out to see if the towing gear was safe. The risk in not updating the running gear is some loose rivets on the minimum side, and I suppose something much worse can always be argued on the maximum side. It's a risk we have taken for a couple of years, but will get the new axles next spring. That coincides nicely with replacing some major segments of outer skin from some bad running gear damage by the PO. Once I get the nice repairs and remodeling done, I want to minimize the earthquake-like conditions that must be created when the shot axles and shocks are subjected to potholes and crummy highways.
Nice work on the MIG welding. That's another benefit of a vintage trailer -- I've picked up some cool tools and skills that I would not have learned otherwise, maybe, most likely -- ok, ok, I do have a craving for cool tools and hot metal.
Trade Wind is a nice size, don't you think? I'll subscribe to your thread. Have fun!
