I ran a new circuit from the fuse panel, all the way up front. I added two lights in the storage hold 2 lights above the dinnette, under the OHC, and I added two 12V aux sockets for USB chargers. I also added a 12V power socket, in the refrigerator access panel for my 12v compressor. I also added a 12v aux socket for the rear bunk. And two more at the radio area, when I moved the radio up..
It was a bit of work to snake a wire fish around the tube, but after that, it was fairly easly. And now I have lots of power.
