We have camped in the winter several times in the past. I can only remember 2 times when it snowed during a trip here on the Wet side. Then the temps stayed close to the upper twenties and we had no freezing issues. In a day or so, the snow was gone. Once was in our Cougar TT and the other was in our WB Class C. Generally our winters are mild enough that freezing isn't a problem but I always winterized my RVs because I remember some winters where the temps did dip into the single digits. I just used air to blow out the lines so it wasn't a big deal to use the RV and then rewinterize. It is much easier to get into the popular campgrounds then and watching a winter storm blow in from the ocean is a treat!. I guess that means most folks aren't as crazy as we were.
