Finally another update......got the ceiling/wiring/roof skin done. Baltic birch 1/8" ply inside and out with insulation too.
I was on the fence about the roof skin, leaning toward PMF. Then I found a local source for aluminum skin at a decent price so I decided to go for it. Happy with the choice.
Also bought a Maxxfan/vent. And ordered my windows.....dang this is getting spendy! Next up is getting my doors built and fitted.
Goal is to have it ready by the end of July.
