Hi, haven't posted in a bit, so here's an update. Removed the rear wall interior panels, removed the linoleum on the stairs, and found there was no rust except a little patch where the door meets the bottom of the stairs, got all of the wires sorted and figured out. Then removed the drivers heater console (will clean and put back in) and capped off the coolant tubes. Then we were able to remove the last of the linoleum and plywood in drivers area. The bus is 100% free of fiberglass insulation, linoleum, and plywood as of now. So here is a picture of the drivers area, we paid very close attention to the wires we were removing, and labeling and the bus still starts and moves with all this removed.
