#4. Washing
Completely wash the exterior of the RV, cleaning debris from the slides and the seams. This step will help prevent leaks and tears. A clean rig will make detecting issues easier to spot.
Fully extend the awning and wash it; let it dry completely and then roll back up for the season. Place a slip-on awning cover as a final step of weather protection.
#5. Check for Needed Repairs
Next thing to know when learning how to winterize an RV? You need to inspect the seams and seals and repair any torn or cracked areas. Look over all exterior areas for any type of damage. If the problem is not something fixable on your own, schedule a repair with a reputable company.
#6. All About the Water
When winterizing a camper, all the water from the rig’s system will need to be emptied. Hot water heater and holding tanks, waterlines and toilet; all lines need to be flushed to prevent freezing. Replacing the water should be potable antifreeze. Pump this product into the water system, filling it completely full. Doing so will prevent cracking, freezing and other damage caused from cold temperatures.
Another tip is to remember to turn off the faucets and close off the valves; remember to recap the drains, too.
Clean the sewer hose and store it within the RV.
