Ok boys & girls.. now that there is a wall on the left side, it's time for another dry fit.
I am happy to say that things are gonna line up pretty nice. I wont have to trim the stone at all as it comes up between the subwoofer box & the cabinet. The horizontal 2x4 will be placed on the top edge of the deck of the platform so I dont waste a whole course of stone there just to be hidden by the mattress.. the upside of that decision is I will have left over to run that course on the right side of the van.
