I cancelled my reservation in Mesa AZ

Major focus for winterizing an RV is the removal of all water from the plumbing system along with any items that can be harmed by sub-freezing temps. Process it pretty simple overall and starts with emptying tanks including hot water and opening low drain points. Some follow up with using an air compressor to further remove water from the lines. Many RVs come with a bypass kit already installed near water heater to add RV antifreeze with minimal effort. If you have an exterior shower be sure that it is winterized properly as it is easy to forget. We keep our rig plugged in over the winter and batteries stay charged, many who don't plug in remove batteries and periodically charge or trickle charge them.
