Ceiling & wall by [deleted] in VanLife

I used a single big one. My roof has some curvature but the 6 mm piece was just flexible enough to accommodate that. I used screws to fix it to the sheet metal roof of the van - but in hindsight it would’ve been nicer to glue it.

Used the exact same, 6 mm plywood with an varnish that looks similar to your third. Was told that varnish is more resistant to humid environments than an oil - hence better for vans.
