Bottom line...if its gonna freeze..then winterize. Winterizing isn't the big horrible chore so many people make it out to be...it's pretty simple, it's very inexpensive, and since we don't know just what mother nature will throw our way, if you are in an area where you can get some of these harder freezes than just winterize! Besides you learn a lot of invaluable info about your trailer at the same time. The potential repairs could be a whole more time consuming and expensive and just a pain to deal with.
