Check Window and Door Seals

As the leaves begin to change colors and the temperature starts to drop, you know it’s time to get your RV ready for the cooler months ahead. One critical yet often overlooked area of concern is the condition of the window and door seals. These seals are your first line of defense against inclement weather, be it rain, wind, or even snow. Worn-out or damaged seals can lead to leaks, drafts, and even mold—issues that no one wants to tackle in the middle of a trip.

Fortunately, checking and repairing your window and door seals is a straightforward process. By dedicating a little time and effort now, you can save yourself from bigger, more expensive problems down the road. You’ll not only keep your RV cozy and dry but also improve its energy efficiency.

Our goal is to keep water out! Water and RVs do not mix. The seals around the doors and windows is an important barrier to protect our RV.

Step-by-Step Guide to Checking Window and Door Seals

• Step 1: Start with a Visual Inspection – Look for any visible cracks, gaps, or wear in the seals.
• Step 2: Use the Hand Test – On a windy day, place your hand near the edges of closed windows and doors to feel for drafts.
• Step 3: Check for Water Leaks – Spray water on the seals and observe if any water seeps through.
• Step 4: Assess the Rubber – Feel the rubber seals. If they are hard or cracked, they likely need to be replaced.

We have camped in the rain several times, which helps us see in real time if we have any leaks. On one trip we had water pouring through the skylight into the shower and the rest of the bathroom. Needless to say, that was a long weekend! Still being in the camper and seeing what was happening saved us thousands of dollars in damage!

If you find that your seals are lacking in any way, don’t fret. Most hardware stores carry sealant products specifically designed for RVs. Always opt for quality products to ensure a long-lasting seal and consult your RV’s manual for any specific recommendations or guidelines.

Pro Tip: Stick with RV-specific sealants! Dicor makes good sealant products. I used silicon and now every spec of dirt sticks to it. That was a bad choice. Next time we will use Dicor 351 available from Amazon.

Your RV is your home away from home, and taking the time to perform these checks will go a long way in ensuring it stays in top shape. After all, preventative maintenance is always better—and cheaper—than dealing with problems as they arise.

Clean and Lubricate Slide-Outs

When we began searching for our first RV camper I was initially against slide-outs. Talk about a decision I would have regretted. The extra space provided by the slide-outs in our fifth wheel is unbelievable!

However, slide-outs collect dirt, debris, and even small critters if not properly maintained. Especially during the fall, leaves, twigs, and other debris can become trapped, causing the slide-outs to operate less smoothly or, worse, become damaged. Cleaning and lubricating the slide-outs are essential steps in your fall RV maintenance routine.

5 Tips for Properly Cleaning Slide Outs

• Start with a Brush: Use a soft-bristled brush to remove loose dirt, leaves, and other debris from the slide-out’s exterior and the surrounding area.
• Use the Right Cleaner: Opt for a cleaner specifically designed for RV exteriors or slide-outs. Make sure to read the instructions carefully. We use WD40 Slide Out Lube to keep our slide rails lubricated (check the price on Amazon).
• Spot Clean Stains: Use a microfiber cloth and a gentle cleaning solution to target any stubborn stains or spots.
• Don’t Forget the Seals: While you’re cleaning, pay special attention to the rubber seals. Clean them with a rubber seal conditioner to keep them in good shape. We use WD40 Rubber Conditioner to keep the rubber on our slide-outs in good order!
• Dry Thoroughly: Before retracting the slide-outs, make sure to dry all areas completely to prevent mold and mildew.

Pro Tip: Consult your RV’s manual for any brand-specific recommendations or restrictions. 

A well-maintained slide-out not only ensures a trouble-free trip but also preserves the value of your RV for years to come.

Inspect the Roof and Apply Sealant as Necessary

Your RV’s roof is one of its most critical components, acting as the first barrier against the elements. However, the roof is often the most neglected part of an RV, primarily because it’s out of sight and out of mind. As you prepare your RV for the fall season, allocating time for a thorough roof inspection is crucial. 

A compromised roof can lead to issues such as water damage, which is both expensive to repair and detrimental to the overall health of your RV.

Before you even set foot on your RV roof for an inspection, it’s essential to prioritize safety.

RV roofs can be slippery and hazardous, especially in wet conditions.

4 Tips to Stay Safe on the RV Roof

• Wear Proper Footwear: Choose shoes with excellent grip to prevent slips or falls.
• Use a Sturdy Ladder: Always use a stable ladder for climbing onto the roof and make sure it’s properly anchored.
• Verify your RV Roof Can Support Your Weight: RV Roof’s have weight limits and some cannot be walked on at all. Do your homework before climbing on the roof!!
• Work with a Buddy: Having someone spot you from the ground or assist you on the roof can make the process safer and more efficient.

When you’re safely on the roof, look for any signs of damage such as cracks, holes, or worn areas. Pay particular attention to the seams, as these are often the first places where leaks occur. If you find any issues, consider applying a sealant to patch up minor problems. For more significant damage, it may be wise to seek professional repair services. 

Always consult your RV’s manual for specific guidelines on the type of sealant that is safe and effective for your roof material. Most RV manufacturers recommend inspecting the RV roof every 90 days. Regular roof inspections and timely repairs are integral to maintaining your RV’s longevity. 

By being proactive in your fall maintenance routine, you can prevent minor issues from turning into significant problems, ensuring that your travels are trouble-free, and your RV stays in excellent condition for many seasons to come.

Wash the Exterior

Maintaining a clean exterior for your RV is about more than just aesthetics; it’s a vital part of long-term care. Dirt, grime, and road salt can build up over time, leading to corrosion and damaging the exterior paint. In the fall, your RV may also have residue from tree sap, bird droppings, or insects, all of which can be corrosive if left untreated. 

Washing the exterior of your RV not only keeps it looking its best but also allows you to closely inspect the exterior for any signs of wear and tear or damage.

We like to wash our Fifth Wheel every couple of months. After our Christmas / New Year’s trip, I will wash our camper to help get the salt and road grime off it before we store it until spring.

Wash Your RV The Easy Way!

• Rinse First: Start by rinsing off loose dirt and debris with a hose, starting from the roof and working your way down to prevent redepositing dirt.
• Prepare Cleaning Solution: Use a specialized RV or automotive soap. Mix it in a bucket according to the manufacturer’s instructions. I like to use the Chemical Guys Foaming Soap. Check out the latest prices on Amazon.
• I use my power washer to apply soap with a soap cannon. It makes me feel like a kid again! And it makes the job faster. Some RV owners claim this is too much pressure. The soap cannon is very low pressure.
• Use a Soft Brush or Sponge: Dip a soft brush or sponge into the cleaning solution and gently scrub the RV’s exterior in sections.
• Pay Attention to Stubborn Areas: For areas with stubborn stains or residues like tree sap, you may need a specialized cleaner.
• Rinse Again: After scrubbing, thoroughly rinse off the soap using a hose, starting from the top and working your way down.
• Optional Dry Off: Use a soft, absorbent towel or a chamois to dry off the RV, which helps to prevent water spots. I don’t do this on the RV. It’s a giant pain in the neck and in my view wasted time! But, I don’t get paid to detail RVs so do what works for you!
• Optional: Apply Wax: If desired, apply a layer of RV-specific wax to protect the exterior and give it a nice shine. We really like Meguiar’s Hybrid Ceramic Spray Wax. It’s easy to apply and so far seems to be keeping the black streaks from appearing on our fifth wheel! Check out the latest prices on Amazon for Meguiar’s Hybrid Ceramic Spray Wax.

Other Considerations

It’s best to choose a cloudy day for this activity to prevent the soap from drying too quickly on the RV’s surface, which can leave unsightly residues. While this task might seem daunting due to the RV’s size, breaking it down into sections can make the job more manageable. 

This simple act of maintenance can go a long way in preserving your vehicle’s lifespan and appearance.

Inspect the Tires for Damage and Wear

After experiencing several tire blowouts, I am particularly sensitive when it comes to tire maintenance. Tires are among the most crucial components of your RV, as they bear the entire weight of your vehicle and its contents. 

Proper tire maintenance is essential for ensuring a safe and smooth driving experience. 

With fall coming around, this is the ideal time to conduct a thorough inspection of your RV tires. It’s crucial to look for signs of wear or damage that could compromise your safety on the road.

Pro Tip: RV owners should perform a visual check before every RV trip along with checking the air pressure in each tire.

One of the first things you should do is visually inspect each tire for obvious signs of deterioration or damage. This preliminary check can help you identify whether you need to seek professional help for a more thorough examination and possible tire replacement.

Examples of Visible Damage to Look For:

• Sidewall Bulges: These could indicate a weak spot on the tire and are prone to blowouts.
• Deep Cuts or Gashes: Such defects can compromise the structural integrity of the tire.
• Tread Separation: If you notice that the tread seems to be peeling away from the rest of the tire, get it inspected immediately.
• Irregular Wear Patterns: Uneven wear could be a sign of alignment issues or problems with tire balance.
• Foreign Objects: Sometimes, objects like nails or screws can become embedded in the tire. While the tire may not immediately deflate, driving on it can exacerbate the problem.

If you notice any of these signs, it’s best to consult a tire professional for a comprehensive evaluation. They can confirm whether the tire can be repaired or if it needs to be replaced. Ignoring these warning signs could lead to more severe issues, such as blowouts or accidents, particularly when driving at high speeds or in challenging conditions.

Maintaining your tires in top condition is essential not only for your RV’s performance but also for the safety of everyone on board. Always remember to also check your tire pressure regularly and adjust as needed according to your RV’s manual. 

With proper tire maintenance, you can hit the road with peace of mind, knowing that you’ve taken steps to ensure a safer and more enjoyable journey.

Remove ALL Food and Perishable Items

We remove food items after EVERY trip. While it may be overkill, we want to minimize the risk of rodents entering our camper. Mice can do tremendous damage to a camper!  

As the camping season winds down and the chill of autumn sets in, it’s crucial to remove all food and perishable items from your RV. 

Leaving food in the RV during the off-season can attract pests and lead to unpleasant odors, not to mention the potential for food spoilage. Even canned goods can freeze and burst in cold temperatures, creating a mess that you’ll need to clean up later. 

Taking the time to remove food items can save you a lot of trouble and make your RV ready for the next adventure.

Checklist of Items to Remove

• Fresh fruits and vegetables
• Meat, dairy, and eggs
• Canned goods
• Opened condiments like ketchup, mustard, and mayonnaise
• Snacks like chips, cookies, and candy bars
• Spices and herbs
• Beverages, including water bottles
• Any open or unsealed dry goods like flour, rice, or pasta

While it’s essential to remove all food items, some RV owners opt to keep a small stock of non-perishables stored in airtight containers. In our view, you are just creating work for yourself later and sending an invitation to all the pests in the storage yard to visit your RV! 

If you choose to do this, there are a few tips to keep in mind for off-season food storage.

3 Tips for Off-Season Food Storage

• Use Airtight Containers: Store any dry, non-perishable items in airtight containers to keep them fresh and protect against pests.
• Choose a Cool, Dry Place: Temperature fluctuations can affect food quality. Store your containers in a cool, dry place inside your RV.
• Label and Date Everything: Use labels to indicate what’s inside each container and when it was stored. This way, you’ll know what you have and how long it has been stored when the next season rolls around.

Leaving food in your RV during the off-season can result in a host of problems that you’ll have to deal with later. It can attract rodents and insects, lead to bad smells, and even cause damage to the interior of your RV. As part of your fall maintenance routine, make it a habit to clean out your food storage areas completely. This simple act can go a long way in preserving the quality and longevity of your RV.

By following these guidelines, you can ensure that your RV is ready and waiting for your next big adventure, without any unpleasant surprises. It’s one less thing to worry about as you dream about the open road and plan your trips for the coming year.

Clean the Interior (Sweep, Vacuum, Mop, Wipe Everything, etc.)

The interior of our camper endures a fair amount of wear and tear, especially during active camping trips. While cleaning the RV is always a staple in our post-trip routine, maintaining a pristine interior can still be a challenge. Anyone who has taken their camper to the beach can attest that some sand always seems to linger, no matter how thorough the cleanup.

Over time, dirt and grime builds up in crevices, causing wear and tear. Plus, bacteria and mold can grow in neglected, damp areas. Especially after a season of fun and travel, your RV’s interior will benefit greatly from a deep cleaning.

Checklist of Items to Clean

• Floors: Sweep, vacuum, and mop
• Carpets: Vacuum
• Kitchen Area: Wipe down all surfaces, clean appliances, and sanitize the sink
• Bathroom: Scrub the toilet, sink, and shower, and wipe down all other surfaces
• Windows: Clean the inside and outside
• Upholstery: Vacuum and spot clean if necessary
• Sleeping Areas: Wash all bedding and wipe down mattresses and bunk frames
• Cabinets and Drawers: Empty, wipe down, and consider lining with shelf paper
• Ceiling: Check for cobwebs or mold and clean accordingly
• Vents: Dust and clean all air vents

To tackle this extensive list efficiently, consider breaking the task into smaller, manageable sections. You can even make it a family affair, assigning tasks to different family members. 

Armed with the right cleaning supplies—such as multi-surface cleaners, disinfectants, a good vacuum, and plenty of microfiber cloths—you’ll have your RV’s interior looking as good as new in no time.

Remember that some areas require special attention or cleaning products. For instance, leather upholstery may require a specific cleaner or certain surfaces may need to be treated with a protective spray. 

Always refer to your RV’s manual or consult with the manufacturer for specific cleaning guidelines. A clean and fresh interior will not only make your next trip more enjoyable but also help maintain the overall value of your RV.

Replace Air Filters

We barely remember to change the air filter in our house and the thermostat beeps at us to change it! Air filters are an often overlooked component of RV maintenance, yet they play a crucial role in keeping your living space free from dust, allergens, and odors. Air filters also help ensure that your HVAC system runs efficiently. 

In most RVs, you’ll find air filters located in a few key areas: behind return air grilles for the central air system, inside roof-mounted air conditioners, and sometimes integrated into specialty appliances like range hoods or dehumidifiers.

5 Signs That Air Filters Need Replacement:

• Decreased Airflow: If you notice that the air coming from your vents isn’t as strong as usual, a clogged filter could be the culprit.
• Unusual Odors: A musty or stale smell can indicate a dirty filter.
• Increased Dust: If you find yourself having to dust more frequently, it might be time to change your filters.
• HVAC System Noises: Strange noises from your HVAC system can sometimes mean a blocked or dirty filter.
• Visible Dirt and Grime: If the filter looks dirty to the eye, it’s a clear sign that it’s time for a replacement.

Step-by-Step Guide on Replacing Air Filters

• Identify the Filter Location: Refer to your RV manual to locate all the air filters within your unit.
• Turn Off the HVAC System: Always switch off the system for safety before replacing the filter.
• Remove the Old Filter: Open the access panel and carefully slide out the old filter.
• Check the Filter Size: Ensure that your new filter matches the dimensions of the old one.
• Insert New Filter: Slide the new filter into place, making sure to align it as indicated by the arrows or other markers for airflow direction.
• Secure and Seal: Close and secure any latches or screws for the access panel.
• Turn the System Back On: Once the new filter is securely in place, turn your HVAC system back on and check for proper airflow.

Replacing air filters is a straightforward task that can have a significant impact on the air quality inside your RV. Make it a routine part of your seasonal maintenance, especially in the fall when you’re preparing your vehicle for storage. Your respiratory system, as well as your RV’s mechanical systems, will thank you for it.

Check Smoke Alarm, Carbon Monoxide Detectors, Fire Extinguishers (Replace as Necessary)

Safety should always be a top priority when it comes to RV maintenance, and fall is an excellent time to check all your safety devices. 

Start with your smoke alarm and carbon monoxide detectors. These lifesaving devices are often battery-operated and should be checked regularly to ensure they’re functioning correctly. Similarly, fire extinguishers should be inspected for integrity and expiration dates.

Pro Tip: Test your smoke alarm and carbon monoxide detectors at the start of every trip!

Step-by-Step Guide on Checking Safety Devices:

• Smoke Alarms and Carbon Monoxide Detectors: Press the test button on each device. You should hear a loud, clear siren. If the sound is weak or nonexistent, replace the batteries and test again.
• Fire Extinguisher: Check the pressure gauge to make sure it’s in the green zone. Also, inspect for visible damage like corrosion or leakage.

If any of your safety devices fail these basic tests or are nearing their expiration dates, replace them immediately. Also, make sure to keep spare batteries in easily accessible locations in case you need to replace them while on a trip.

While it’s easy to focus on the more visible aspects of RV maintenance, neglecting safety devices can have severe consequences. Make it a routine to perform these checks as part of your fall maintenance or even more frequently. It’s a small investment of time and money that could prove invaluable in an emergency.

Prevent Rodent Infestation

As the temperatures drop in the fall, rodents start looking for warm places to nest, and an unused RV can seem like an ideal home for them. 

A rodent infestation can lead to severe damage to your RV’s wiring, insulation, and interior. Plus, they can carry diseases, making them a health hazard as well. Therefore, taking preventive measures against rodent infestation is crucial.

Step-by-Step Guide on Preventing Rodent Infestation:

• Inspect for Entry Points: Examine your RV’s exterior for cracks, holes, or other potential entry points for rodents. Seal any openings you find. We use steel wool to fill all the holes. Pests are unwilling to chew through the steel wool. Check out the latest prices on Amazon.
• Remove Food Sources: Ensure that all food and perishable items are removed from the RV.
• Set Traps: Place humane traps or bait stations in areas where rodents are likely to enter or nest, such as near food storage areas and in dark corners.
• Use Repellents: Consider using natural rodent repellents like peppermint oil or commercial solutions designed for RVs. We use Grandpa Gus Mouse Repellant and the Ultrasonic PestContro to help reduce the chances of any pest invading our fifth wheel!

By taking these preventative measures, you substantially reduce the risk of facing a rodent infestation in your RV. Combine this with regular inspections, especially during the off-season, to ensure that your vehicle remains rodent-free.

Both these sections on safety devices and rodent prevention may seem like small tasks in the grand scheme of RV maintenance, but their importance can’t be overstated. Taking the time to attend to these details will contribute to a safer and more enjoyable RVing experience.
