Yeah!! Just a few. Mostly 12v for interior/exterior lights, USB charging points and trailer lights. Small bundle for 240v AC power points. And then there's the solar cables from 6 panels on the roof. Oh I shouldn't forget the 6 speaker cables servicing 3 audio zones - and the HDMI cable for the exterior entertainment outlet.
All of the electronics contained in one cupboard. I'm sick of pulling up seat cushions and getting down on my hands and knees to get to batteries, fuses and other charging devices. Getting a bit old for that.
