Do you use white=negative, black=positive for DC in your RV?

I have a Winnebago. My stock hot cables are all yellow including those going to the trailer plug. White is ground. Each cable has a specific code printed on the insulation. The codes are labeled in the schematics. A clean design and well documented.

Winnebago does use green to ground the propane pipes.
