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.
The furnace has been ducted to provide heat to the below floor water tanks and plumbing to help prevent freezing. 12-volt heat pads are also installed with the fresh and black/gray water tanks. These pads are individually switched, located at the bottom of the roadside cabinet beside the refrigerator, which allows the saving of battery power in freezing temperatures. RV antifreeze may be used to protect the black/gray tank. 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 the tanks have been emptied.
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 parked trailer.
When parked in sub-freezing temperatures, make sure to keep a full supply of LPG and plug into a 120-volt power source whenever possible.
NOTE: Drain and winterize the trailer if the water systems are not being used during winter traveling.
