When RV owners hear the word “winterize” it conjures up thoughts of protecting the RV plumbing system from freezing temperatures. The definition for “winterize” is to prepare something, like a house or automobile, to withstand cold winter conditions. This is interesting because RVs are both a house and a vehicle. So, in addition to winterizing the RV plumbing system we need to be concerned about preparing the RV’s interior, exterior, and chassis components for the harsh winter months too.
With that said the most logical place to start is to protect the RV plumbing system from damage, since this is the number one problem RV owner’s face during periods of freezing temperatures. If you don’t protect the RV plumbing system any water remaining in the water lines or tanks can freeze, expand and break fittings and lines. This can be a very costly mistake next spring!
