CLASS C MOTORHOME
17 WINTERIZATION
17.1.3 FURNACE
During below freezing temperatures, the furnace
must be operating at all times. Remember, al-
though the furnace runs on LP gas, it is powered by
12-volt electrical. the battery in the motorhome
must be up to normal levels, 12 volts or else the
furnace will not operate.
17.1.4 WASTE SYSTEM
To prevent winter freeze-up, add regular RV anti-
freeze through the toilet and kitchen drains, directly
into the holding tanks. Be sure to add suffficient
amounts in order to protect the total volume of the
holding tank.
Do not use alcohol-based anti-freeze or other
petroleum products.
17.1.5 FRESH WATER SYSTEM
The fresh water system consists of the water tank,
the pump and all lines. This entire system is
contained inside heated interior spaces. In cold
weather, it is necessary to have the furnace operat-
ing. The heated air in the motorhome will circulate
around the water tank, pump and water pipes and
reduce the possibility of freeze-up.
CAUTION
In northern climates, during the
winter season, winter diesel must
be used to prevent fuel gelling.
Gelling could cause the engine to
stop or make it difficult to start.
17.1 COLD TEMPERA-
TURE
OPERATION
All XL motorhomes are built for three season travel
including:
1. Urethane installation undercoating.
2. Insulated and heated holding tank compartment
(XL only).
3. All plumbing located in heated interior spaces.
Although your motorhome is designed to withstand
winter temperatures, we cannot guarantee the
vehicle not to freeze. Certain precautions should be
taken in preparing for sub-zero temperature travel-
ling.
17.1.1 CHASSIS
Check coolant level and add anti-freeze, if required,
to protect against lowest expected temperature.
Change engine oil to the recommended viscosity to
aid cold weather starting. See the manufacturer's
manual for further recommendations.
17.1.2 LP GAS
When travelling in winter, propane is recommended
as it will vaporize in extreme cold (above -42 C).
Butane is not recommended due to its high vapori-
zation temperature (0
°C). Use of butane in cold
temperatures may block the system and cause
components to malfunction. Add approximately .25
liters of methyl alcohol to your LP gas container to
prevent freeze-up.
