Extend the RV Season

• 1). Make sure your Tango has a factory-installed heated, insulated and enclosed underbelly. Contact an authorized Tango dealer and order it if you don't have one. Install the underbelly or have the dealer do it.
  
  
• 2). Install weather stripping on doors, windows and access panels. Purchase weatherstripping kits for each door and window. Buy window weatherstripping kits for each access panel. Clean the surface to which you'll apply stripping. Measure the opening and cut the stripping. Apply window weatherstripping between the sash and frame. Apply a door sweep on the bottom of each door and weatherstripping along each side. Apply strips along each side of any access panels. Consult the illustration contained in the kit of where and how to apply the stripping. Make sure the surfaces to which you apply stripping are dry and the outside temperature is above 20 degrees Fahrenheit (minus seven degrees Centigrade).
  
  
• 3). Check your owner's manual for the furnace location, as well as the filter size specific to your model of Tango trailer. Change the furnace filter.
  
  
• 4). Check under the Tango Trailer. Contact a Tango dealer or RV service department to check that there are no exposed tanks, pipes and elbows without heaters. Choose and install a heating system that suits your family's RVing style. Most heating systems use ducted heat, which requires a detailed RV retrofit. Ducted heat is effective to 20 degrees Fahrenheit (minus seven degrees Centigrade) and requires the furnace to run continuously. An independent heating system that requires minimal retrofitting and makes the RV a four-season vehicle is preferable in northern climates.
  
  

Get Ready for Storage

• 1). Turn off the water heater. Attach a hose to the drain valve. Open the valve and allow the water to drain into a large bucket. Join the two water lines joined to the heater to act as a temporary water bypass.
  
  
• 2). Drain the fresh and gray water tanks. Turn on all hot and cold taps, allowing them to drain. Remember to drain the shower. Make sure no water is left in the toilet.
  
  
• 3). Add RV antifreeze to the fresh water tank. Shut each tap when antifreeze begins to drain from it. Don't forget the shower and toilet as well. Close the gray water valve. Pour some antifreeze down the shower and sink drains. Pour antifreeze into the toilet and flush. Add more antifreeze to the toilet bowl.
  
  
• 4). Remove batteries from smoke detectors, clocks and other appliances. Unplug all appliances and electronics, including alarm clocks.
  
  
• 5). Remove all food from the cabinets and refrigerator to prevent mice, insects and vermin from wintering inside your RV. Spray an insecticide approved for indoor use for added protection, preferably one that lasts three to six months. Place an open box of baking soda inside your refrigerator to prevent a musty smell developing while it's shut down.
