I've seen a lot of videos on insulation and paneling but none show the detail work. What's the best way to deal with wires like in pic, and the finish edges around the doors, contours, or even the supports like in the pic? I was thinking putting these wires in the cavity, but looks like I'd have to disconnect everything to re-route. Also, on paneling, do you just use sheet metal screws to the metal struts and corners, I've seen actually put 1x4 first, but that seems to be just taking space? And do I want to fill that whole space with insulation to match strut? I used 1" but would still need more. Or long it's there, it's insulating? I'm no too worried about R factor, in Ca where we are, I won't be in van in the extremes. Very new at this! So many ideas, so little space!
