Interior lining & insulation
So that we can really feel good in our future camper, we decided to replace the gray, rather dreary interior paneling with a self-made one made from oiled poplar plywood . At the same time, we took the opportunity to better insulate our bus. With the help of self-adhesive insulating material, we filled in the voids between the interior trim and the body . In order to have enough light in the bus in the future, we then installed five LED spotlights, three in the ceiling and two in the trunk lid . We did not provide the areas that will later be covered by the cupboard and the kitchenette with an interior cladding - also against the background of cost savings.

Poplar plywood 3mm thick, the amount depends on the panels that are exchanged
Copy stencils & oils
In the next step, we used the removed panels as templates and transferred the shape, including the holes for the screws or clips, to the plywood. It's best to put something heavy on the stencil so that it doesn't slip when you pause . We used a jigsaw to cut the plywood to size . We made the holes with a wood drill. In addition, we cut out the holes in which the LED spotlights will later be inserted.
Remove cladding & insulation
First, we removed the old interior panels. To do this, the Phillips screws must be loosened. The ceiling covering can be removed using an Allen key , then the clip can simply be pulled out. As soon as all cladding has been removed, we have insulated the cavities with Armaflex . To do this, the strips can simply be cut to the correct size with scissors and finally glued directly to the inside of the body .
We have reworked the cut edges with sandpaper so that they are even and round. Now the surface was briefly roughened and then the panels could be oiled. Simply use an old cotton rag. After the wood has been oiled, it is best to remove the excess wood oil again with a clean rag so that everything is later evenly distributed. After the oil dried, we used the spotlights and glued the transformer to the side of the panel that was later to be hidden. You can use silicone or similar glue very well. We directly extended the cables of the LEDs so that we could lay them correctly right away - because as soon as the cupboard or other furnishings are installed in the bus, it will be quite a hassle to remove the interior cladding again.
Installation & wiring
In the last step we reinstalled the panel with the screws and clips. Since the plastic clip like to go broke, we have this ordered. The ceiling is best installed in pairs if you have no supports. Where the LED transformer is located, you should cut out a piece of the insulation so that it has enough space and you can properly reinstall the ceiling. It is best to think in advance where your switches for the spotlights will later be, so that you can lay the cables correctly right away. In order to be able to continue opening the tailgate from the inside, we simply attached a cord to the opening latch and led it out of the panel where we can best get it later.
