Hi,
I have just finished this on my own van. The kombi mat was a good idea that I picked up from this forum which I used myself along with 12mm ply floor and 2mm Altro walkway.
A few tips.. or things I wish I would have know before hand.
One piece ply if possible so you don’t see joins through the Altro floor. I made my own an joined it with biscuit
When making the cut outs for the rails in the ply you need make a ‘pocket’ for the springs on the rails to fully go back otherwise it will be very hard to get the trims back on when all finished.
I found the floor a bit too flexible with only the mat so I put some wood at the busy areas for a bit more support. See picture. Also gave me something to fix to.
I cut my floor square where the step is using my kombi step trim thinking it would be okay but now I have looked at the caravelle ones they have a small radius cut out so it has given me a problem which I haven’t fixed yet. I have just added a 14mm spacer under the kombi step ‘for now’
