COLD TEMPERATURE STORAGE
SPRING STARTUP
After storing the motorhome for an extended period of
time, run the water pump to pressurize the water system
and check for leaks. Visually inspect the water system
for 15 minutes to ensure there are no leaks.
Clean all your appliances and have the LP Gas line
purged by a qualified service center. Ensure everything
in the motorhome is working correctly. Refer to the
chassis manual in the Motorhome Information Kit for
any chassis maintenance recommendations.
COLD TEMPERATURE OPERATION
The plumbing system in this motorhome is not designed
for cold weather use. Temperatures at or below freezing
will cause damage to the plumbing system.
CHASSIS
Check engine coolant level and add antifreeze,
if required, to protect against lowest expected
temperature. Change engine oil to the recommended
viscosity to aid cold weather starting. Refer to the
chassis manual in the Motorhome Information Kit for
further recommendations.
LP GAS
Use propane for winter traveling because it will
vaporize in extremely cold temperatures -40 °F (-40
°C). Butane is not recommended due to its high
vaporization temperature 32 °F (0 °C). Using butane
in cold temperatures may block the system and cause
components to malfunction.
WASTE SYSTEM
Prevent winter freeze-up by adding regular non-toxic RV
antifreeze into the toilet and kitchen drains to protect the
holding tanks from freezing. Be sure to add a sufficient
amount of non-toxic RV antifreeze to protect the total
volume of the holding tanks.
ᘐ WARNING
Do NOT use alcohol-based antifreeze or other
petroleum products.
