The first thing that is going to freeze when camping in cold weather is the white water hose coming into the RV. We carry the heated hose for those rare times we experience night time temps in the mid to high 20's. It is just as easy though to disconnect and run off your on board tank/pump.
Pex plumbing will take some minor freezing. Not sure I wouldn't be taking more winterizing steps if I was camped in the panhandle of Florida right now, but down here in SW Florida there are certainly no worries.
