This probably wasnt the best solution - or the cheapest. I'm supposed to do a whole writeup on Sprinter-Source but i'll let the pictures do the talkin' on ADV.
Started by making the 6" panels:
Then got these pine strips called "lattice" that come in 16' lengths that I cut (in-store) down to 11' - you only pay per foot for what you take - it was still too expensive and not very strong. What I ended up with looks like an capsized boat.
I had to build these brackets in the back to give something for the lattice strips to attach to:
Then the side carpet was glued only to the bottom 6" panel and stapled to the strip at the top so that I can tip the whole 6" panel up for wiring. The panels are held on with 5mm stainless socket bolts into rivnuts in the roof bows. Same with the headliner except they're 6mm.
