Added a cover for the AC unit to both shade it and not have to see it from the backyard. I made the panels all removable with four screws and even added some handles to make moving easier for service.
I learned that one can spray the bottom of the 4x4’s with a rubberized spray paint for the part submerged underground. This should reduce damage by moisture. In the second image, I also added an eye bolt to one of the concrete pours for a future project with the generator.
