I met with an electrician and got some advice about a year ago on wiring my camper (1969 Holiday Rambler -- full rebuild), but then life got busy and I haven't done much and now I am rusty on some details getting back to it.
I read somewhere recently (maybe here? can't for the life of me remember) that 12vdc wires and 110vac wires should never touch or cross. I do know that it was not something that the electrician had pointed out, because I didn't plan for it after talking to him. Is this true?
I'm using a WFCO power center, and running both into the power center, so with different wires needing to run in different directions from the same thing, it seems damn near impossible for none of them to ever touch or cross.
In the original build, most of the 110vac ran through the walls, and most of the 12vdc ran through the ceiling, but there was a roof AC with 110vac wire that had to have crossed dc wires in the ceiling (I ripped it out so long ago, but it's hard to configure a way it wouldn't have).
How much do I need to worry about this? If I'm using proper wire gauges so they're not getting hot, is it a big deal? Or should I rethink the whole thing to avoid it?

In house builds, low voltage and 110AC wires should not be run thru the same holes, chase or in the same box. This may be what you are remembering.
I keep my 110 wiring separate from 12 volt wiring but sometimes they are close together. I don't have any trouble running 12 volt wiring apart from the 110; they don't have to touch.
All wiring should be neat and attached to framing or in junction boxes. 1/2" spacing should be plenty between wire types.
I'm curious-why did you rip the air conditioning wiring out?

I replaced the roof air conditioner with a MaxxAir fan (and had to remove all of the old wiring thanks to mice). I want to keep 110ac running to the roof vent, though, in case myself or anyone else wants to reinstall roof ac in the future. But that means that the 12vdc for the fan (as well as for the clearance marker lights and other things that run through the ceiling) do end up close to or crossing that 110ac wire.
1/2” spacing is good to know and I can certainly manage that by securing them apart from each other where they come near. Thank you Vikx!

Glad you are keeping the old 110 wiring. Even if you never use it, very handy to have for the future...

Doesn’t matter if the insulation of the wire are both rated for the highest voltage.
