Where white is used, that is true (assuming wiring was coded to begin with).
Marine and automotive standard is red = positive, and black = negative.
House wiring (120V): Black = hot, white = neutral, green = ground, red = switched (for 3 way switches, ceiling fans, etc).
RV wiring: who knows? Depends on what the installer had handy. The entire
back side of my converter/distribution panel is white. The white wires are connected to an array of red, black and white wires with crimp-on wire nuts. As an engineer (electrical), I am absolutely disgusted. And yet everything works!
just my experiences
