If I’m being honest, winter camping has brought my wife and I some of the fondest and most stressful memories in RV life. Winter camping in an RV can be magical — snow-dusted forests, cozy nights by the heater, and the tranquility of off-season travel. But when your RV starts to feel like an icebox, the dream can quickly turn into a chilly nightmare. No one is enjoying anything if their RV is freezing.

Whether you’re braving subzero temperatures or facing an unexpected cold snap, this guide will help you tackle freezing conditions and keep your RV warm, functional, and comfortable.

 

Why Is My RV So Cold?

RVs are not always built with harsh winter conditions in mind. Thin walls, minimal insulation, and draft-prone windows make it easy for the cold to seep in. Add to that any gaps or cracks in seals, and your RV can feel more like a refrigerator than a cozy home. But don’t worry — there are plenty of solutions to keep the cold at bay.

 

Step 1: Inspect your RV for drafts and leaks.

Cold air creeping in through cracks and seals is one of the main culprits when it feels like your RV is freezing. Start by inspecting these critical areas.

• Windows and Doors. Look for drafts and gaps around frames. Use weather stripping or non-sag to create a tight seal. If you want to know what sealants to use in different situations, you check out this RV sealant article. 
• Roof and Vents. Examine your roof seams and vents for cracks or deteriorating sealant. Self-leveling sealants are a go-to solution for patching these areas. 
• Slide-Outs. Check the seals around your slide-outs for damage or wear. Flexible sealants can quickly fill in any gaps and flex with movement.

Pro Tip: Use a flashlight or incense stick to detect drafts. Shine the light or waft the smoke near seals. If you see light or the smoke moves, you’ve found your culprit.

 

Step 2: Add insulation where it matters most.

Insulating your RV is crucial to fighting those freezing temperatures. Here are some quick upgrades to help trap the heat.

• Windows: Cover windows with reflective insulation like Reflectix to prevent heat loss. For added coziness, hang thermal curtains or shades.
• Underbelly. If your RV will be parked for an extended period of time and has an exposed underbelly, add foam board insulation or skirting to block cold air from circulating underneath.
• Vents and Skylights. Foam vent cushions can help seal off these areas, which are often significant sources of heat loss.
• Floors. Use small area rugs or mats to insulate floors and create another layer between your feet and the cold floor.

Pro Tip: Even something as simple as a draft stopper or “door snake” under your entry door can make a big difference.

 

Step 3: Heat your RV efficiently.

The key to staying warm isn’t just generating heat — it’s keeping it from escaping. Here are the best ways to heat your RV.

• Furnace. Your built-in furnace and is your first lines of defense, but furnaces can drain propane quickly. Make sure they are well-maintained and use propane sparingly, because in some cases it is your only heating and cooking source.
• Heat Pump. Some rigs have a heat-pump combo with their A/C unit, and if you have a good generator or are connected to shore power, they can be a great source of warmth.
• Portable Heaters. Electric space heaters are a great backup for maintaining warmth in small areas. Look for energy-efficient models with safety features like tip-over protection. Know that they draw a lot of power, so if you are off grid, then always monitor your battery levels.
• Heated Accessories. Heated mattress pads or blankets can make your sleeping area toasty without overworking your furnace. A regular heating pad that you find at a pharmacy is also a cheap but effective option for warming up under the covers at a lower electric draw.

Pro Tip: Use a combination of heating sources to distribute warmth evenly while conserving energy. Know that propane and electricity can drain quickly if you are off-grid and using these methods. So, setting the temperature for a bearable level like 60 and wearing layers helps to conserve resources. 

 

Step 4: Protect your water system from freezing

Frozen pipes and tanks are a winter camper’s worst nightmare. Here’s how to keep your water system functional.

• Heated Hoses. Invest in a heated water hose to keep your fresh water flowing. Plug it in before temperatures drop.
• Tank Heaters. Install heating pads on your freshwater, gray, and black tanks. These will prevent freezing even in frigid conditions.
• Insulate Exposed Pipes: Wrap exposed pipes in foam insulation or heat tape to keep them from freezing.

Pro Tip: If it’s particularly cold, leave a faucet dripping slightly to keep water moving through the system and prevent freezing.

 

Step 5: Plan for power and propane.

I touched on this before, but keeping your RV warm in freezing temperatures often means relying on power and propane. Here’s how to stay prepared.

• Stock Up. Always carry extra propane tanks if possible and/or fill up often to prevent running out.
• Monitor Usage. Track your propane and power levels closely so you never run out of heat or battery power.
• Portable Power. A good solar/battery setup or portable generators can help ensure you’re never left without power for heaters, electric blankets, et cetera.

 

Step 6: Stay comfortable inside.

Finally, don’t forget about creature comforts to make your RV feel like home, even when the weather outside is frightful.

• Layer Up. Wear several layers of clothing to stay warm without overworking your heating system.
• Hot Drinks or soup. For us, nothing beats a cup of hot coffee in the morning, but hot cocoa or tea on a cold night goes a long way in the winter—keep a thermos handy to enjoy throughout the day. Personally, I’m a big soup guy too, so any tasty soup for lunch or dinner helps warm me from the inside.
• Extra blankets. Adding extra blankets and throws around the rig always helps, and it’s a great way to get cozy for movie night. Whether it feels like your RV is freezing, or not, it’s a good idea to keep these on-hand if you’re a four-season RVer.
• Curtains. In some RVs, adding something as simple as curtain to separate a cold room from one that you are trying to warm can save on resources and keep the temperature where you are more comfortable.

 

Warmly Embrace the Winter RV Adventure

Yes, winter camping in an RV has its challenges. But with proper preparation, it’s an experience like no other. From snowmobiling Yellowstone to skiing and snowboarding just steps from our home on wheels, we have had some amazing winter RV experiences. That’s why recommend trying it — at least once. And if you follow these tips on how to insulate your rig, prep your heating sources, seal up drafts, and keep your resources in check, you will be able stay cozy and enjoy the magic of winter landscapes. Embrace the adventure, and remember: A well-prepped RV is a happy RV, even when the temperatures dip below freezing!

When winter camping calls, your RV’s ability to stay warm and weatherproof becomes the cornerstone of comfort. Whether you’re navigating snow-covered forests or enjoying a quiet lakeside retreat, the unsung hero of your camper’s winter readiness is its RV sealant.

Making sure your RV is buttoned up effectively protects against cold drafts, moisture, and potential long-term damage. (And sealing up your RV can involved more than just RV sealant.) But to get the results you want, you need to know the basics. So, in this article, we’ll focus specifically on the different types of RV sealant, when and where to use them, and some top product recommendations to make your winter RV adventures cozy and trouble-free. 

 

Why RV Sealants Matter in Winter

As almost all RV owner know (or will soon find out), winter conditions can be brutal on an RV. Ice, snow, and fluctuating temperatures challenge even the most well-maintained rigs. Gaps in seals can allow freezing air or water to creep in, leading to drafty interiors, moisture damage, or even structural issues. This is where RV sealants come to the rescue, acting as a barrier to keep your RV protected and insulated. They help keep the weather out and the comfort inside of your home on wheels.

 

Types of RV Sealants and Their Uses

The world of RV sealants can feel overwhelming, but understanding the key types and their applications will help you choose the right product for each job.

 

1. Self-Leveling Sealants

Best for: Horizontal surfaces like your RV roof. Self-leveling sealants are designed to spread evenly as it cures, creating a smooth, watertight seal on flat areas.

Top Pick: Dicor 501LSW Self-Leveling Lap Sealant

• Why It’s Great: This sealant is a go-to for sealing seams and vents on rubber or TPO roofs. It’s UV-stabilized and resists cracking, which is essential during winter freezes and thaws.
• Pro Tip: Apply on a clear, dry day to allow proper curing before exposing it to snow or rain.

 

2. Non-Sag Sealants

Best for: Vertical surfaces like sidewalls, windows, and doors. Non-sag sealants are formulated to stay in place without dripping or sagging, even on inclined surfaces.

Top Pick: Geocel ProFlex RV Flexible Sealant

• Why It’s Great: Known for its flexibility, ProFlex works well on fiberglass and aluminum and withstands temperature extremes.
• Pro Tip: Use masking tape around your application area for a cleaner finish, especially if working on visible sections like windows.

 

3. Butyl Tape

Best for: Underneath fixtures like vents, skylights, and window frames. Butyl tap is pliable, adhesive tape that conforms to irregular surfaces for an excellent initial seal.

Top Pick: 3M Butyl Tape

• Why It’s Great: Ideal for creating a strong base seal before applying a lap or non-sag sealant over it.
• Pro Tip: Always remove old butyl tape before reapplying to ensure a secure fit.

 

4. Silicone-Based Sealants

Best for: Non-porous surfaces, such as glass or metal. Silicone-based sealants provide excellent water resistance and flexibility, but not suitable for areas exposed to high UV light or on rubber roofs.

Top Pick: Permatex Clear RTV Silicone Adhesive Sealant

• Why It’s Great: This sealant is a reliable option for quick fixes on windows or mirrors.
• Pro Tip: Use sparingly, as silicone can be challenging to remove and is incompatible with some RV surfaces.

 

5. Specialty Sealants for Extreme Conditions

Best for: Areas exposed to heavy wear or harsh weather. These specialty sealants are formulated to handle extreme cold, water immersion, or high movement.

Top Pick: Sikaflex-221 Multi-Purpose Sealant

• Why It’s Great: Known for its durability, it adheres to multiple surfaces, making it versatile for tough jobs.
• Pro Tip: Allow extra curing time in colder temperatures for maximum adhesion.

 

6. Flexible Sealants for All-Weather Versatility

Best for: Sealing joints and cracks that require flexibility and durability. These sealants are weatherproof, paintable, and adaptable to movement. All of which make this kind of RV sealant ideal for RV surfaces prone to shifting or flexing.

Top Pick: Flex Caulk Waterproof and Weatherproof Sealant

• Why It’s Great: Flex Caulk stands out as an all-purpose, heavy-duty sealant perfect for RV use. Its flexible, weatherproof formula makes it an excellent choice for sealing around windows, vents, trim, or any area exposed to movement or environmental stress. The built-in trigger applicator simplifies application, ensuring a precise and clean finish without needing extra tools. Once cured, Flex Caulk dries to a paintable surface, blending seamlessly with your RV’s exterior for a polished, professional look.
• Pro Tip: Plan your application based on weather conditions, as colder or humid environments may slightly extend curing time. For larger projects, keep a damp cloth handy to smooth out edges and achieve an even seal.

 

My Personal Must Haves

With space being a premium in an RV, if I could only have two on the road, it would Dicor Lap Sealant and Flex Caulk. Both are easy to apply and super reliable. We recently used Dicor for our full solar and electrical upgrade when installing new solar panels. Its self-leveling properties and durability made the process seamless and gave us peace of mind for long-term weatherproofing. You can check out the full installation in this video on our Instagram. 

We also use Flex Caulk around the RV in a pinch because it works well and comes with a squeeze handle. So, it is quick and easy to use on the go. There is no caulk gun needed.

 

When and Where to Apply Sealants

Proper application is just as critical as choosing the right sealant. Here’s a breakdown of common areas that benefit from RV sealant maintenance.

Roof Seams and Vents. Check for cracks or peeling sealant, especially around vents, skylights, and air conditioning units. Use self-leveling sealant for the best results.

Windows and Doors. Inspect for gaps where cold air or moisture could seep in. Non-sag sealants or butyl tape work well here.

Underbelly and Storage Compartments. Look for potential openings where road debris or water might infiltrate.

Slide-Out Seals. Ensure the rubber seals are in good condition and supplement with a compatible sealant for gaps.

 

Additional Tips for Winterizing with RV Sealant

Preparation Is Key. Clean all surfaces thoroughly before applying sealant to ensure proper adhesion.

Temperature Matters. Most sealants cure best above 50 degrees Fahrenheit. So, plan applications during milder winter days or indoors.

Inspect Regularly. A quick monthly check of your seals can save you from expensive repairs down the line.

RV sealants may not be the flashiest part of RV maintenance, but they’re undoubtedly among the most important. With the right RV sealant and application, you can ensure your RV stays warm, dry, and comfortable all winter long. Whether you’re boondocking in snowy mountains or parked at your favorite winter campground, a well-sealed RV is the key to worry-free adventures. Don’t overlook this essential step. Your RV (and your wallet) will thank you!

Like my spirit animal, the bear, when the days grow shorter and the air gets cooler, we RV owners know when it’s time to prepare for winter hibernation. But proper RV storage isn’t just about parking your rig and calling it a season. Rather, it means ensuring that when spring rolls around, your RV is ready to hit the road — without surprises. Trust me, as someone who’s learned a few lessons the hard way, I can tell you that prep is essential when storing your RV for the winter.

So, if you want to do it the right way (you do), here are the steps you need to take. It involves a little bit of cleaning, a grasp of RV winterization, and a few common-sense pointers. But together, all of it will help keep your RV safe, sound, and ready for adventure once the frost melts.

 

1. Thoroughly clean your RV — inside and out.

Cleaning your home, whether on wheels or sticks and bricks, is never fun. That said, it’s way easier to do it early than late. Early, in this case, means when you’re storing your RV for the winter. Your future spring-self will thank you.

• Exterior Cleaning. Start by giving your RV a good scrub to remove road grime, dirt, and lingering bugs. Apply a coat of wax to protect the exterior from harsh winter weather. Consider a good coat of wax. It not only shields against moisture but also makes spring cleaning much easier.
• Interior Cleaning. Empty your fridge and pantry of all food. Vacuum the floors. And wipe down every surface. Mold, mildew, and pests are your winter enemies, and a clean RV helps keep them away. Don’t forget often-overlooked areas like storage compartments, under seats, and in the bathroom. You don’t want that road fry that fell under the seat a couple months back to be the reason you come back to ants or mice.

 

Pro Tip: To prevent any unpleasant surprises, leave your refrigerator and freezer doors slightly open. A small box of baking soda can work wonders for absorbing odors during storage. But remember to properly clean, dry, and turn off your fridge beforehand.

 

2. Winterize your plumbing system.

Failing to winterize properly can lead to costly repairs, as I learned the hard way. One year, I didn’t drain and blow out the lines properly, and when I dewinterized, the outdoor shower connector had cracked. The result? Water shot everywhere. And our departure was delayed by a full day as I scrambled to clean up, make a run to the hardware store, and repair the issue. It’s the perfect example of learning from my mistakes.

• Drain and Flush. Start by draining all water from your freshwater, gray, and black tanks. Use your RV’s water pump to remove any lingering water and then flush the system with nontoxic RV antifreeze to protect your pipes from freezing. You should also look for a low-point drain to help you with the process of clearing out your lines.
• Water Heater. Turn off and drain the water heater completely. If your RV has a bypass kit, use it to save antifreeze during the process.
• Protect Every Faucet. Pour a small amount of antifreeze into your sinks, shower drains, and toilet to protect the P-traps and seals.

 

Pro Tip: Use a checklist to ensure no faucet or drain is overlooked. Trust me, one missed step can lead to a mini disaster come spring.

 

3. Inspect and protect your RV exterior.

Your RV’s exterior takes the brunt of the meanest season’s harshest conditions. So, give it some TLC before storing your RV for the winter.

• Check Seals and Roof. Carefully inspect all seals, seams, and the roof for cracks or damage. Apply a weatherproof sealant if needed, to prevent any weak spots from getting worse.
• Tires. Inflate your tires to the manufacturer’s recommended pressure and cover them to protect against UV rays and cold weather. If possible, use leveling blocks or lift the RV slightly to reduce stress on the tires.
• RV Cover. Invest in a breathable, high-quality RV cover to shield your rig from snow, ice, and debris. Ensure the cover is snug to avoid moisture buildup underneath.

 

Pro Tip: Park on a level surface and use wheel chocks to prevent movement during storage. If you’re parking on dirt or gravel, placing plywood or some leveling blocks under the tires can help prevent sinking.

 

4. Handle your power system with care.

Your RV’s power system needs special attention to ensure it’s ready to roar back to life in spring. 

• Remove Batteries. If possible, remove your RV’s batteries and store them in a cool, dry place. Use a battery maintainer to keep them charged and ready.
• If You Can’t Remove Batteries. Disconnect the battery terminals to prevent phantom power draw. Check the batteries periodically to ensure they maintain a charge and aren’t exposed to freezing temperatures.
• Unplug Everything. Disconnect all appliances, electronics, and propane tanks. This not only prevents potential damage but also reduces the risk of fire.

 

Pro Tip: For rigs equipped with solar panels, covering them up when storing your RV for the winter is good practice as well. It’s a quick way to shield them from the elements.

 

5. Keep those pesky pests out.

Nobody likes unwelcome guests, especially rodents and insects that can wreak havoc during storage.

• Seal Entry Points. Inspect your RV for any small gaps, vents, or cracks. Use foam sealant or wire mesh to block these entry points.
• Repellents and Traps. Place peppermint oil-soaked cotton balls, dryer sheets, or safe repellents inside your RV to deter rodents. Set traps in areas where pests might be tempted to nest.
• Food-Free Zone. Remove all food and even crumbs to ensure pests aren’t attracted to your rig.

 

Pro Tip: Regularly check your RV during storage for signs of pests. The earlier you catch an issue, the easier it will be to address.

 

6. Store your RV smartly.

The right storage location can make all the difference in protecting your RV.

• Indoor Storage. Whenever possible, store your RV in a climate-controlled facility to shield it from extreme weather. This will also minimize so much of the prep work, because it won’t be in the elements.
• Outdoor Storage. Choose a secure location away from overhanging trees or potential hazards. A good RV cover is essential in this case.
• Parking Prep. Ensure your RV is on a level surface. For added protection, consider using skirting to block cold air from circulating under the RV.

 

Pro Tip: Visit your RV periodically during the winter to check for any issues, such as leaks or pest damage.

 

Bonus tip: Get a jump on your spring checklist.

As you prepare your RV for winter, create a checklist for spring maintenance. Include tasks like recharging batteries, flushing the water system, inspecting seals, and cleaning both the interior and exterior. Having a plan ready will make your transition back to the road seamless.

 

Please learn from my mistakes.

Winter RV storage can seem daunting, but with a little effort, you can avoid costly repairs and ensure your rig is ready to roll when the snow melts. If there’s one thing I’ve learned, it’s that proper winterization is worth every minute. Trust me, a few hours of preparation now will save you from a lot of frustration later. So, grab your checklist, follow these tips, and give your RV the care it deserves this winter. 

If you’ve spent any time RVing, you’ve probably discovered that not all parts of the adventure are scenic sunsets and s’mores by the campfire. One unavoidable task that every RVer has to face is emptying the black tank. And necessity of that task pushes forward the uncomfortable question: Who is going to empty the black tank? In my marriage, like many other RV families we’ve met on the road, this fun assignment is taken over by one person. And that person is me. I have offered to be the bearer of black news in my marriage, and it gives me a few points every time. Happy poopsy-free wife, happy life.

While it may not be the highlight of your trip, mastering this job is essential to keeping your home on wheels running smoothly. (And trust us, it’s a whole lot easier with the right preparation and tools.) With a little know-how, you’ll soon have this process down to a science, leaving more time for the parts of RV life you love.

Ready to dive in? Let’s get started!

 

Step 1: Gather the Right Tools (They Make All the Difference)

When it comes to emptying your black tank, preparation is key. Having the right tools on hand not only makes the process more efficient but also keeps things clean and—most importantly—minimizes unpleasant surprises. Here’s a checklist of what you’ll need:

• Sewer Hose and Fittings. A durable, flexible sewer hose, often affectionately called the “stinky slinky,” ensures a secure connection between your RV and the dump station.
• Disposable Gloves. These are non-negotiable. Protect your hands with a thick, disposable pair for each dump session.
• Clear Hose Extension.While it’s not the prettiest part of the process, a clear extension lets you see when the tank is completely flushed.
• Sewer Hose Support. Use a support to create a smooth slope for the hose, helping gravity do the work and preventing any unpleasant backups.

 

Pro Tip: Store all sewer-related tools in a separate, labeled bin. This ensures they stay away from other camping gear, preventing contamination and making cleanup quick and easy.

 

Step 2: Position Your RV for Success (Double-Checking Matters)

Whether you’re at a dump station or a full-hookup campsite, how you position your RV makes a difference. You’ll want to park close enough that your sewer hose can reach the dump port comfortably without stretching. Take a few extra moments to ensure the ground is level and that the sewer connection is secure.

When setting up, always double-check that you’ve attached the hose to the correct outlet. It sounds obvious, but on some rigs, the gray and black tank handles look identical.  And you don’t want any mishaps — trust us on this one!

Pro Tip: Always empty the black tank first before opening the gray tank valve. This way, the gray water helps flush out the hose, leaving it cleaner and reducing odors.

 

Step 3: Hook Up and Empty the Black Tank (Slow and Steady Wins the Race)

Now comes the main event. Start by putting on your gloves and connecting your sewer hose to the RV’s black tank outlet. Secure the other end at the dump station, and make sure everything is locked tight to avoid leaks. Slowly open the black tank valve—don’t rush it. Let the contents drain completely, and give it a few extra moments to ensure everything flows out.

If your RV has a built-in black tank flush, connect a dedicated hose to the flush inlet. Running fresh water through the tank helps clear out any stubborn waste or toilet paper that might linger. No built-in flush? No problem—a portable rinse wand or backflow connector like this will do the trick just fine.

Pro Tip: Make sure that your black tank valve is closed and add a little extra water from your RV toilet foot-flush – I tend to add just a few seconds – so that what is inevitably left over in the tank doesn’t completely dry and get worse.

 

Step 4: Flush the Gray Tank and Wrap It Up (You’ve Done the Dirty Work)

Once the black tank is empty and closed, it’s time to open the gray tank valve. The soapy water from your sinks and shower will flush out any residue in the sewer hose, leaving it cleaner and fresher. This step also makes disconnecting the hose far less messy.

After the tanks are empty, give your sewer hose a quick rinse — many dump stations have a non-potable water spigot for this purpose. Once everything is clean, disconnect the hose, cap the outlets, and store everything neatly in your designated bin.

Pro Tip: Perform one final dump and rinse at the end of each trip if possible. This ensures your tanks stay clean during storage and prevents buildup that could lead to clogs or odors later on.

 

Step 5: Use Tank Treatments to Keep Things Fresh (Say Goodbye to Odors)

To keep your black tank smelling fresh and functioning properly, it’s a good idea to use an RV-specific tank treatment. These treatments help break down waste and prevent odors from becoming an issue, especially during warmer months. Drop-in pods are a popular option because they’re easy to use—just toss one into the toilet, and you’re good to go.

If you’re staying at a full-hookup campsite, resist the urge to leave the black tank valve open all the time. Keeping the valve closed allows the tank to fill, which helps waste break down more effectively and prevents unpleasant buildup known as the “pyramid of doom.”

Pro Tip: Always keep your drinking water hose and black tank rinse hose separate — cross-contamination is the last thing you want on an RV trip!

 

Avoiding Common Mistakes (Because We’ve All Been There)

1. Forgetting Gloves. Even if you think you’re quick, wear them. You’ll thank yourself later.
2. Skipping the Tank Rinse. It only takes a few extra minutes and will save you headaches in the long run.
3. Leaving the Black Tank Valve Open at All Times. This can lead to waste buildup, causing clogs and foul odors.
4. Not Checking Connections. A loose fitting can turn into a big mess fast—double-check everything before opening valves.

 

Wrap-Up: Embrace the Process and Enjoy the Journey

Emptying the black tank may not be the highlight of your RV trip, but it’s a necessary part of the lifestyle. Once you’ve mastered the process, it becomes just another routine task, like setting up camp or cooking dinner outdoors. Plus, knowing you have clean tanks means less stress and more time to focus on the adventures that lie ahead. With the right tools, a little patience, and some practice, you’ll be able to handle this job with confidence. And, who knows? You might even become the go-to tank expert in your campground! (If that’s something you actually like).

Happy RVing, and may your tanks always flow smoothly! Also, if you’d like a little video tutorial walking you through the process step by step, watch this.
