Built and framed out the area above the dash. Mounted the speakers. Then I mounted the bracket to hold the indoor unit and hung the unit for now. I cut a hole through the back and ran the lines in. I also started fishing the 25′ copper lines set through from under the bus to the indoor unit. I messed up a bit, see the next post.
The Blue tape on the ceiling is for future lights. You can see my blue tape markings around the window for the wood blocks I put in to screw the bottom speaker panel in.
