mhowell, considering where you live, I wouldn't worry much about winterizing your camper, as the main reason you winterize it would be to keep from freezing the lines and tanks from freezing weather.
Since the temp drops below freezing here in Tennessee I try to get my winterized just after my last camping trip for the year and well before the first freeze. I have a fitting that you can purchase at any camper sales, including Wal-Mart that screws into the water hookup and enables you to attach a airhose and blow all the water out of the lines. You can also use the DC pump to pump RV antifreeze into the lines to keep them from freezing. It's also a good time to clean out the camper and get rid of food products and not needed supplys.
The reason you un-winterize is to clean the chemicals out of the lines and ready it for the upcoming camping season. I connect the water hose up to the water connection and fill the lines with fresh water and flush out the chemicals, plus run fresh water though the DC pump and flush it out also.
My Brother-in-law doesn't winterize his camper in Shreveport, La, as the weather usually don't drlop below freezing.
I think also the term, de-winterzie also can be used to get your camper ready, like a spring cleaning. Washed up and shined and ready for the camping season. It's also a good time to work on getting rid of that 'musky' smell from it sitting up. Another reason to install Vent covers. I leave my vents open most of the time, especially when it's sitting up.
