Pro Tip: Consider installing a water filter after flushing to further improve water quality.
3. Sanitize the Water System
After flushing, it’s important to sanitize your freshwater tank and lines to eliminate any bacteria that may have accumulated over the winter.
- Prepare a sanitizing solution. Mix 1/4 cup of household bleach for every 15 gallons of water capacity in your freshwater tank.
- Pour the solution into the freshwater tank.
- Fill the tank completely with water.
- Turn on the water pump and open all faucets and fixtures, running them until you smell bleach.
- Let the solution sit in the system for at least 4 hours, but preferably overnight.
- Drain the tank and lines.
- Flush the system with fresh water until the bleach smell is gone.
4. Check and Charge the Batteries
Your RV batteries are crucial for powering essential systems.
- Inspect the batteries for corrosion or damage.
- Clean the terminals with a wire brush and baking soda solution.
- Check the water level in lead-acid batteries and add distilled water if needed.
- Charge the batteries to full capacity.
Consider using a battery maintainer to keep your batteries charged throughout the RV season.
5. Inspect and Test Appliances
Before your first trip, ensure all your appliances are functioning correctly.
- Refrigerator: Clean the interior and check for proper cooling.
- Water Heater: Inspect for leaks and test the heating element.
- Stove and Oven: Clean the burners and oven and check for proper ignition.
- Furnace: Check for proper operation and inspect the venting system.
- Air Conditioner: Clean the filters and test the cooling performance.
Remember: Propane appliances should be inspected for leaks by a qualified technician.
6. Check Tires and Brakes
Tire and brake safety are paramount.
- Check the tire pressure and inflate to the recommended PSI.
- Inspect the tires for wear and tear.
- Check the brake lights and turn signals.
- Inspect the brake lines for leaks.
Consider a professional brake inspection before your first long trip.
7. Check Exterior Lights and Electrical Connections
Ensure all exterior lights are working properly.
- Check all running lights, brake lights, and turn signals.
- Inspect the electrical connections for corrosion or damage.
- Test the shore power connection.
Faulty lighting can create a dangerous situation on the road.
8. Inspect and Lubricate Moving Parts
Lubrication is key to preventing wear and tear on moving parts.
- Lubricate door hinges, locks, and latches.
- Lubricate the stabilizer jacks and tongue jack.
- Inspect the awning and lubricate the moving parts.
9. Restock Supplies
Make sure you have all the necessary supplies for your first trip.
- First aid kit
- Toilet paper and paper towels
- Cleaning supplies
- Freshwater hose and sewer hose
- Leveling blocks and wheel chocks
10. Final Inspection and Test Run
Before hitting the road, perform a final inspection of your camper trailer.
- Check all doors and windows to ensure they are properly sealed.
- Test all appliances one last time.
- Take a short test run to ensure everything is functioning correctly.
Frequently Asked Questions (FAQs)
Here are some frequently asked questions about dewinterizing your camper trailer:
1. Can I just skip the sanitizing step?
No, you shouldn’t skip sanitizing. Even if you thoroughly flushed the system, bacteria can still accumulate in the freshwater tank and lines during the winter months. Sanitizing eliminates these bacteria and ensures your drinking water is safe. Skipping sanitization puts your health at risk.
2. How do I dispose of RV antifreeze?
RV antifreeze (propylene glycol) is generally considered non-toxic and can be disposed of down most drains. However, always check with your local regulations for specific guidelines. Never dispose of automotive antifreeze (ethylene glycol) in this manner, as it is highly toxic.
3. How much bleach should I use to sanitize my water system?
The recommended ratio is 1/4 cup of household bleach per 15 gallons of water in your freshwater tank. Using too much bleach can damage your system, while using too little may not effectively sanitize it.
4. What if my water pump won’t prime?
This is a common problem. Make sure the water tank has water, and check for any air leaks in the suction line. Sometimes, you may need to manually prime the pump by pouring water into the intake line.
5. My water smells like antifreeze after flushing. What should I do?
Continue flushing the system with fresh water. It may take several flushes to completely remove the antifreeze smell. Consider using a water filter to help remove any lingering tastes or odors.
6. How often should I sanitize my water system?
It’s recommended to sanitize your water system at least twice a year: once when dewinterizing in the spring and again after a period of heavy use, such as after a long camping trip or before putting the RV into storage. Regular sanitization is essential for maintaining water quality.
7. What if I find evidence of rodents?
If you find evidence of rodents, such as droppings or chewed wires, thoroughly clean the affected areas and inspect for any damage. Set traps to catch any remaining rodents and seal any entry points to prevent future infestations. Rodent infestations can cause significant damage to your RV.
8. Can I use vinegar instead of bleach to sanitize my water system?
While vinegar is a natural alternative, it’s not as effective as bleach at killing bacteria. If you prefer to use vinegar, use a 50/50 solution of vinegar and water and allow it to sit in the system for at least 24 hours before flushing. Vinegar is a milder option but may not provide the same level of disinfection.
9. How do I know if my tires need to be replaced?
Inspect your tires for signs of wear and tear, such as cracks, bulges, or uneven tread wear. Use a tread depth gauge to measure the tread depth. If the tread depth is below the legal limit, or if the tires are more than five years old, they should be replaced. Tire failure can be extremely dangerous.
10. What if my propane tank is empty?
Have your propane tank refilled by a qualified professional. Never attempt to refill a propane tank yourself. Make sure to check for leaks after the tank is refilled.
11. How do I check for propane leaks?
Apply a soapy water solution to all propane connections. If bubbles form, there is a leak. Tighten the connections or replace the fittings as needed. Propane leaks can be extremely dangerous and should be addressed immediately.
12. What tools will I need to dewinterize my camper trailer?
Common tools include: a socket set, screwdriver set, pliers, adjustable wrench, hose clamps, a water pressure regulator, RV antifreeze, a water filter, and a water hose. Having the right tools will make the dewinterization process much easier.
By following these steps and addressing any potential issues, you can ensure your camper trailer is ready for a season of safe and enjoyable adventures. Remember to prioritize safety and consult with a qualified technician if you have any doubts or concerns. Happy camping!
