I will forward per your suggestion to Mark BC.
I have made quite a few additions since that first build in 2008. Perhaps I will add to this post some of the more recent additions. Below is a stereo, speakers, & cabinet I added. One photo shows the inside of the cabinet where I put my DVD's and CDs. The other photo shows the speakers, radio which has CD player and iPOD/USB inputs. The meter next to the speakers is my amp meter showing how the battery is charging from solar panel.
