Here is the progress so far. This is as cheap as I could be! The bus was acquired through a trade and the previous owner painted the windows black. it was a hassle to remove so I embraced it and painted over it. I've started the buildout. I have a small 100W solar panel charging two 100AH batteries that go to an inverter. I recently got a larger solar generator with 4 150W panels also. This has been fun so far, I am loving it!
