Joe has it all covered. I'm merely putting icing on his cake.
We blow out the lines using a fitting that attaches to the shore water inlet valve and attach an air compressor to it. I'm not certain where we go it but I would be astonished if Camping World didn't carry it, or any good RV shop.
Blows it out just about as fast as I can type this.
The hot water heater...first step is to make sure the power switch is OFF. Then, flip the pressure relief valve and STAND ASIDE, unless you want soaking wet pants. Once it's stopped dribbling, THEN remove the anode and allow it to drain. The air pressure will blow water out of it. You may want to stick a rag in it to allow the water to wick out, but in any case, make sure you make some sort of annotation to yourself that the anode is OUT and do NOT turn on the hot water heater. What we did was take the old anode, which had corroded like it's supposed to, sawed off the long part leaving just the plug, and put the plug in a little, just enough to keep critters out of it. I also tie a bit of orange engineer tape to the door to remind me next spring that the HWH is empty and has no anode.
Make sure there's a little antifreeze in the bowl of the toilet, too.
It takes about three bottles of pink RV antifreeze to winterize our 17' SD. Maybe that's overkill, but what the heck, it's cheap insurance.
