Before we could attach the wooden slats in the high roof, we lined the entire roof with Armaflex.
We bought planed spruce / fir wood in 300 cm from the hardware store. We used a total of 22 slats. At the beginning we finished it with a wood glaze to protect the slats from moisture.
Since our GRP high roof is very unevenly arched and has some bulges, cutting and attaching it was a really time-consuming task. With frequent measurements and trials, we were finally able to screw all the battens to the reinforcements in the GRP. It is important to choose the optimal length for the screws so that you won’t get out of the roof at the end.
Using 4 more long boards, we built a shelf on the left and right that contains all the things that we have in daily use. With the help of another board, we built a closed compartment above the cab. Another compartment should also provide more storage space above our bed.
