This step actually went much faster than I had hoped: At 8:00 we had an appointment, at 9:00am the tools were unloaded after coffee and at 16:00 we were finished with three roof hatches and a window - and that with minimal collateral damage.

Before the complete interior is covered with insulating material we would like to use the beautifully exposed holes of the numerous structural elements to thread in the cables. This page serves more to provide some basic food for thought - the respective setup depends too much on your van or your connection wishes.

The exterior paint of my van was - for a commercial vehicle - in good condition, but in the hold the paint was already worn off by packages and shoe soles or partially rotten. And all in all quite dirty. Since I didn't want to invest weeks in a van conversion, which then has to be dismantled again because it rustes underneath, it was clear: This has to be fixed first.

In order to be able to screw everything that comes afterwards comfortably - and that with conventional screws - I recommend to install a substructure. This is especially necessary for the floor, as it is the only way to create the necessary distance between the sheet metal floor and the camper floor for insulation and hoses.
