I am cutting the internal roof panels today and am thinking about how I'm going to mount them? I think running wooden 'spars' the length of the van would make sense but I have thermoliner installed covering the whole roof..... and then how would you stick the wooden spars up even if I didn't have the thermoliner, glue? I am using 5mm ply, which will then be carpeted. I think I may need multiple attachment points as it may flex and wobble when moving if not mounted/screwed down properly.
If anyone has any pictures of how they did there's please share.
Cheers
