Well thank you, cevans! That's so kind of you to say.
I've made some progress on other projects inside the van lately but haven't had time to post about them yet, so I'll try to get to that soon, but as a sneak peek, here's some photos of the ceiling panels (with lights! on dimmers!), and the beginning of the wood faces on the lower cabinets.
We are using Baltic Birch ply on the walls and cabinets (1/2" for cabinet faces, doors, and bottoms that will bear weight; 1/4" for ceiling, walls and non-weight bearing surfaces in cabinets). I've re-built several airstream trailers before and I used a satin epoxy paint for the cabinets, which allowed me to re-use old surfaces where I could salvage them and have them tie in nicely with new surfaces that were added. The epoxy paint is also super durable and easy to clean.
On this build, though, we have (almost) all new surfaces, and the Birch was so pretty. And we were really happy with the wood sealer we used on the counter tops, so we've been evaluating doing the same treatment on the Birch instead of painting it. In general I try to stick to one wood species per space in our designs (vans, trailers, houses) to avoid a busy, competing grain look. But the Birch and Walnut butcher block are so different that we might be ok with it here.... still deciding.
On the ceiling I used Armacost tri-vue lights for downlights and flush-mount L-track for battens.
