Winter Traveling

Traveling in sub-freezing temperatures will require
certain precautions to protect the plumbing system
and your personal belongings from being damaged by
freezing�
Whenever possible, the heat should be kept set to a
constant temperature� It is easier for the furnace to
keep a constant room temperature than allow the trailer
temperature to drop to 50°F, then attempt to raise it to
room temperature�
Some states do not allow LPG to be turned on while
moving� While traveling in these states, simply use
your common sense� How cold is it? How long will
it be before you can turn the heat back on? Is the
temperature dropping or rising? Remember, when
towing at 50 MPH, the wind chill factor will cause the
interior of the trailer to cool much faster than a trailer
that is parked�
When parked in sub-freezing temperatures, make sure
to keep a full supply of LPG and plug into an external
AC power source whenever possible�
Leave cabinet doors, wardrobes, and bed doors
partially open to allow warm air to circulate around
plumbing lines and fixtures. Insulate and/or wrap your
exterior water lines with heat tape�
The furnace on Flying Cloud models, excluding the
20 ft� model, is ducted to provide heat to tanks and
plumbing to prevent freezing�
The 20 ft� model has 12-volt heat pads installed with
the fresh, gray, and black water tanks� These pads are
individually switched� When the outside temperature
is near freezing, simply switch "ON" the holding tank
heaters� Built-in sensors will activate the heat pads
when the contents of the tank drops to 44°F� Once
the liquid is heated and rises to 64°F the heat pads
will automatically deactivate� Switch the power "OFF"
when the ambient outside temperature remains above
freezing or when tanks are empty� To conserve battery
power, RV antifreeze may be used to protect the gray
and black tanks�
The 19 ft. fresh water tank is above-floor in the heated
area of the trailer. The gray holding tank is below floor,
insulated and a 2 in� duct from the furnace supplies
heat to it� The black tank is insulated, however, no
heat is ducted to it� Use RV-approved antifreeze in the
black holding tank to prevent damage to it and below-
floor drain plumbing, if used in temperatures below the
freezing point�
