I have a Greyhawk. On the driver's side, I have two black low point drain valves. They drain the fresh water tank and the water lines. On the other side, inside a storage bin are two more (white valves) which are also low point drains for the water lines and the water heater. I don't HAVE to remove the water heater drain plug to drain the water heater. Redhawk should be similar, I would think, but do not know for sure.
