Installing sunroofs and solar panels in a motorhome / Iveco Daily #1

While the ordered materials and devices are still on the way, I decided to start from the roof. And I was pleasantly surprised, having cut holes for hatches, that the roof was not made of plywood, like walls, but a sandwich panel with solid insulation. So you can not insulate the ceiling. I haven't installed the panels yet. I took two, just to glue the corners. I will attach later.
