When outside temperatures begin to change so does the way you should care for the RV.  Snow, ice, rain and fog require specific preventive maintenance steps to guard against winter related damage.

Fill the windshield washer reservoir with fluid rated for winter use.

Closing the front privacy drapes and running the interior heat can trap cold air on the inside front windshield and cause a build up of condensation.  Do not allow moisture to accumulate and drip down into the dash area.  Open the curtains during the daytime hours and use a clean cloth or paper towels to wipe the window and dash area dry.

Freezing temperatures and wet weather may create sticky outside locks.  Lubricate each lock cylinder on the entry door and cargo doors with WD-40, spray silicone or dry graphite.

If outdoor conditions are dry, slightly open the overhead roof vent to allow a fresh air circulation inside the RV.  Certain model fans are equipped with a rain sensor, which is a small strip located at the top of the fan.  The sensor is designed to turn off the fan and close the dome when it comes in contact with water.  Occasionally wipe the sensor clean with a soft dry cloth to remove dust and grime build up that may interfere with continued operation.

Regular replacement of the roof seals and maintaining the gaskets under the roof A/C will help guard against water intrusion while traveling in rainy weather.   Make note of the vehicle height, including all components such as satellite dome and air conditioner shroud.  Refer to this information when encountering bridge and tunnel clearance signs, which also may be even lower due to packed snow or ice.

In the event a rainstorm occurs while the awning is out, roll up the awning to guard against wind damage.  At the soonest opportunity, extend the awning after the rain has stopped to allow the awning to dry.

If you suspect temperatures are going to drop below freezing and plan to travel the following morning, retract the slide rooms and awnings before going to bed to avoid delaying departure until temperatures warm enough to thaw the fabric.

Disconnect and stow the water and sewer hoses to guard against freezing weather that may cause the hoses to crack.

Heading to warmer climates may require passing through cold temperature regions.  In this instance it is often easiest to leave the water system winterized and minimize usage until reaching above freezing temperatures.  Pack drinking water in jugs.  Protect the black and gray holding tanks from freeze damage with RV approved antifreeze.

Always keep the fuel and propane tanks as close to full as possible.  Foul weather can cause traffic delays, or a shortage of the necessary fuel supplies for operating the furnace and generator.  Keep food supplies well stocked and always have ample amounts of drinking water on board.

During the trip keep close track of weather conditions by tuning into local weather broadcasts and calling ahead for road report information.  It is often better to detour around a storm rather than confront dangerous travel conditions head on.  Carry chains properly fit to the RV tires.  Take it easy and drive slowly.  Don’t assume all campgrounds are open year round.  Consult a current campground directory and call ahead to confirm availability.
