I've got most of the ceiling done in my skoolie, but the big problem that I am having is coming up with a way to transition the wood of the ceiling to the tops of the windows. In a perfect world, I would just attach the wood planks to the ribs like I have been the other 75%, but that will not allow any room behind. Any suggestions or resources would be greatly appreciated.
On a separate note, I have been just popping rough sized insulation board in the space between the ceiling and the roof of the bus. Is there any incremental improvements I could make
