Cold Weather Use; Storage - Cold Weather - Holiday Navigator 2003 Owner's Manual

A motorhome is not designed for extended use in below freezing (32° F/0° C)
weather. However, you may not experience any problems as long as the
temperature does not drop too low. Interior water lines, fixtures, water storage
tanks and pumps are normally protected from moderate freezing temperatures,
as long as the furnace is operating. Exposed drains may freeze quickly. If in
doubt about what temperature the motorhome will tolerate, winterize with
potable antifreeze.
If the motorhome is stored where freezing temperatures may occur, drain
the domestic fresh water loop completely of water. When draining the domestic
fresh water system begin with draining the fresh water tank by opening the
point drain lever for the fresh tank and allowing the water to drain.
NOTE: Ice makers, water filters, water purifiers and water
heaters all use domestic water and should be drained and stored
in accordance with the manufacturer's recommendation for
winterization.
The method chosen to winterize the motorhome and water lines is up to the
motorhome owner. The lines can be air blown to remove standing water or the
lines can be filled with an approved FDA RV antifreeze. Either way, all interior
and exterior faucets need to be opened and closed, one at a time, to be
checked. All low point drains should be opened and the holding tanks emptied.
