Checking for winter damage.
The main reason to winterize an RV is to protect it over the winter. Rain, snow, freezing cold; we get it all in the BC interior, and it can all cause damage.
Avoiding mold and moisture when you RVs are in storage.
We enjoy those warm days in our RVs, but when we winterize our campers, mold and moisture can creep in and need to be treated, or permanent damage can arise.
