I worked on the bus all day today and made a little progress. The side "wings" are welded in, the original inner roof has a hole cut in it and the replacement inner roof has been test fit. There will only be room for 1" of foam board insulation between the layers of roof in the bathroom area as I can't spare any more overhead space. Hopefully I will get the thing completed tomorrow.
