Winterizing in this manner requires you to put more antifreeze in your fresh water tank than the amount normally unusable in your tank. It all depends on the location of the water pickup in the tank.
Many, if not most coaches have a separate pick up tube on the inlet side of the water pump.
The procedure is generally to shut off a valve coming from the fresh water tank, open a valve going to the pick up tube, insert the tube into your gallon of RV antifreeze, run each faucet until "pink" comes out, shut off faucet.
After you do all the faucets, don't forget to pour a little antifreeze into the sink traps, the shower, and the trap in the washing machine (if equipped). Also it helps to use the installed valves to bypass the hot water heater, and then drain the hot water tank, thereby eliminating the need to completely fill the hot water tank with 6 to 10 gallons of antifreeze before it will come out of the hot water spigots.
Many people (myself included) blow out all the lines instead of filling them up with antifreeze, then pour antifreeze in the traps as mentioned above. It takes a LOT less antifreeze, and makes putting the water system back into service a lot easier in the Spring!
If you haven't already, you need to dig into your coach owners manuals for tips on winterizing the water system. If you don't have the manuals post here, and you will probably be provided with links, or the actual manuals in .pdf format!
A last tip, if your RV does not have the antifreeze pickup tube, you can generally install the valves and tubing necessary for under $30.00.
