I'm gonna go ahead call the interior done!
Final piece was the main console/cabinets. I built the unit out of 1/2" birch ply. Just a basic frame with some open shelves, 4 drawers, 12" deep counter top, a holding pen for the potty, and a big center area for water bottle and other items. Gonna skip a sink for now as it's a weekender at this point.
Frame...scribed to the van walls.
One drawer done.
Installed w/ avocado curtain.
At the entrance to the left I did this open shelving. Bluetti battery at the bottom with fuse block for lights and fan tucked behind.
