AIRSTREAM LAND YACHT GAS 
WINTER TRAVELING (Cont.) 
 
Some states do not allow LPG to be turned on while moving. While traveling in these states you must 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, the wind chill factor when driving 50 MPH will cause the 
interior of the motorhome to cool much faster than when it is parked.  
 
1.You must have a plentiful supply of propane gas. 
 
2. If your stay is longer than overnight, you should endeavor to have 120-volt electricity available. The 
batteries, fully charged, will not last more than about 15 hours in freezing weather. Of course, you can run 
your generator to recharge the batteries, or even use the generator continually. Since the generator starts off 
the same battery as the engine, it is recommended to start the generator prior to shutting off the engine. This 
will prevent running the engine battery down should there be a difficulty in starting the generator in the 
cold temperatures.  
 
3. Minimize use of electricity if 120-volt power source is not available.  
 
4. Leave cabinet doors, bed doors and wardrobe doors slightly open at flight to allow circulation of air in 
and around all furniture components 
 
5. Use propylene glycol type antifreeze in waste and drain water tanks to prevent freezing. Quantity of 
antifreeze needed will vary with ambient temperature and the amount of liquids in tank.  
 
6. For extended stays in cold weather, insulate the water line outside the motorhome. You should remember 
that low temperatures in combination with high winds cause an equivalent chill temperature much below 
what your thermometer is reading. For instance, with an outside temperature of zero degrees, and the wind 
velocity of 10 miles per hour, the equivalent chill temperature is minus 20° F. The exterior water faucet has 
an in-line valve inside the motorhome. In below freezing temperatures, shut off the valve inside and open 
the exterior brass valve so it will drain. See the valve section in this book for locations.
