how to completely drain fresh water tank 177

So I have read about de winterizing and Think I got the steps, however the previous owner put pink stuff in the fresh water tank.  I opened the low point plug but there is still water in there,  Is there a trick other than driving around with the low point drain open to get the water out of the tank?  I guess I could jack up the rear but that still won't get all the water out.  I guess I also could just keep adding water until it is so diluted but I hate to waste that many gallons of water before I can even sanitize.

Cut the foam away from the low points. As far as the FW tank, stick hose in fill port, open drain on bottom.. flush to your hearts content, it's all potable.

Once you get the caps off I recommend adding valves in their place.  You can buy ones that will screw right on the original thread.  That was one mod I never got around to with our pod and I regretted it every fall.
