  • Removing fuel from an uncovered tank can freeze in sub-zero temperatures
  • Plan on replacing or draining all fluids in the engine before storing for winter

Step 1: Empty the black water tank

This first step is mandatory when it comes to winterizing an RV, and it will make RV springtime travel much more pleasant. Basically, you need to flush the tank with fresh water by opening the septic pump and allowing it to flush clean. If there is any problem with the system, that’s likely where the issue lies.

This is also a good time to clean out any clogs so that it is easier and faster when you need to use it again come to Spring.

Step 3: Flush the fresh water system

Before you travel or even just turn on the freshwater supply, it’s important to drain and flush all the pipes and tanks. Inspect hoses for cracks or damage, and make sure they’re not pinched or clogged. One way of doing this is by turning on the sink faucet and running it until you see no rust stains in the basin. Then inspect all water tanks, including toilets and black-water tanks, opening taps around them until they are empty.

Step 4: Change Air Filters

It may not seem like a big deal, but they are important as they help control contaminants such as dust and pollen from entering the system. And that saves you from potential allergy symptoms later on down the road.

Step 5: Check tires/air pressure

Next, ensure there are no leaks in the system, including all connections to water systems. Check plumbing connections and faucets throughout the camper for leaks.

Step 7: Clean exterior

To RV spring maintenance a camper, start by checking all the tires and ensuring they are in good shape. Next, wash the outside of the RV with a gentle cleaning agent. Once it’s clean, use a degreaser to clean up any dirty spots on the body before washing again. Last but not least, make sure all exterior lights work before heading inside for final prep work.

Step 8: Clean interior/gadgets

  • 2. Clean roof vents with a brush-type or vacuum cleaner attachment. You may need to clean the screens at this time too.
  • Apply a coat of RV roof sealant around each vent opening and reapply as needed until sealant no longer becomes tacky when applied (usually 3-4 coats).
  • Make sure you have fresh RV antifreeze in your tanks before turning them back on after storing them over winter.
  • Use RV antifreeze during winter to prevent water freezing in the lines and tanks, leading to problems such as black water disposal issues.
  • Store unused RV antifreeze in its original container out of sunlight, where it will not freeze during cold winter (exterior basement storage is recommended).
  • The last step is removing any snow and ice from RV tires and wheels, so they are ready for action!
  • Dewinterizing an RV takes some time, but this 9-step checklist should help make things easier.
