So here are a few pictures of my campable, mostly complete teardrop-with-roof-tent. The remaining work includes some interior trim, the eventual replacement of the HF fenders with the simple round fenders that I prefer, and a paint job for frame, fenders, and tongue box. I like Oliver Green tractor paint at present. Otherwise, I consider it as done as a home project ever is. Pictures:

Here's the hatch all sealed up with simple side lever clasps. I have two small LED lights inside the hatch.

I used three salvaged Hehr windows with simple levers from some old airstream. I was lucky to have a buddy with a lot of trailer salvage, and traded some labor on a house project for three windows. I think they add a vintage look. The three windows add a lot of ventilation and make the small interior less claustrophobic.

Side view with the roof tent deployed. The ladder is weight bearing and the feel with the stabilizer jacks is quite stable. I used rectangular aluminum tubes as a rack, and the tent can removed with the withdrawal of four bolts. The tent weighs about 90 lbs packed.

The galley with the stove and cooler slide stowed. A little thumb catch keeps it from banging under way.

The galley with slide deployed. This arrangement let me create a lot of storage in a short trailer. There's not a lot of work surface, so the folding table is very helpful. But the small cooler and tambour cabinets create a lot of food storage, and I can fit all sorts of pots and pans and plates and stuff in the two lift-up doors above the stove and cooler slide. And I still have large cabinets inside the sleeper for clothes duffles. The tambour doors are among the only novel solutions in this camper, and I do like the way it "shifts" the galley back in this shorty. And I like to think there is some elegance to the way they match the overall profile.

Water heating for coffee.

And me making it.
I got a lot of great ideas by asking questions and just plagiarizing from other's hard work that they posted freely on this website, so I want to let everyone know ho much I appreciate it. I got the materials from all over the place - a lot locally in Colorado, and quite a bit from vendors. Grant Whipp was particularly helpful with design sketches and bits of advice to resolve various problems I ran into.
So thanks!
