Great post! Airstreams are really beautiful. I have watched several of your videos already. This is a huge project that you undertook! It has come out really nice. When you were drilling out the rivets to remove the inside panels, I noticed the rocker type wall switches. I've read that these are the kind of switches needed for 12 VDC systems. The normal 120 VAC switches will burn out when used with DC current. I'm signing off now to watch more of your videos!
