not sure about your coach
but all my 12 volts wires are heavy like that one and either red and white or yellow and white
all our 120 stuff is sheathed in romex covering
i know it looks heavy gauge for 12 volts... but 12 volts requires more amps than 120 and subsequent voltage loss over a set distance, this is why most 12 volt lines are a heavy gauge
hope it helps
