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 chassis.
Check engine coolant level and add antifreeze, if
required, to protect against the lowest expected
temperature.
Change engine oil to the recommended viscosity to
aid cold weather starting.
Refer to the chassis manual in the Motorhome
Information Bag for further recommendations.
LP Gas
Use propane for winter traveling because it will
vaporize in extremely cold temperatures.
Butane is not recommended due to its high
vaporization temperature. 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 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.
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 propane line
purged by an authorized dealer.
Ensure everything in the motorhome is working
correctly.
Refer to the chassis manual in the Motorhome
Information Bag for any chassis maintenance
recommendations.
WARNING
Do NOT use alcohol-based antifreeze or other
petroleum products.
