My CRS is kicking in bigtime, can't remember who's build it was that had a dual 110v/USB port for all 4 bunks. Have you had enough experience in the bus to know if they are needed or overkill. How often were 8 110v, and 4 USB circuits were needed at once?
I'm thinking one on each side supplying 2 bunks would be sufficient and cut down on wiring unneeded port. There will be other ports in the bus if needed.
