As the owner of Cozy Turtle RV Rentals, I’ve seen firsthand how a little preparation goes a long way. People often think Myrtle Beach is immune to harsh winter weather, but that’s a risky assumption. Cold air sneaks in faster than you expect, and even a few nights of dipping temperatures can cause expensive plumbing issues and significant heat loss if your rig isn’t prepped correctly. Winterization of your RV might sound complicated, but I promise it doesn’t have to be.
With a few smart steps, you can protect your plumbing system, prevent leaks, and avoid a lot of winter headaches. It’s one of the most important maintenance tasks you can perform for your investment. And if you’d rather not handle it yourself, my team and I are happy to take care of the entire process for you.
Understanding How Cold Air Impacts Your RV
Cold air is persistent—it will find its way into any small crack, gap, or unsealed opening in your RV. The real trouble starts when the warm, moist air inside your rig meets the cold air seeping in from outside. This temperature difference creates condensation, which can lead to mold, mildew, and wood rot over time. It also forces your furnace to work harder, leading to energy loss and higher utility bills.
Keep an eye out for telltale signs of air intrusion. Do you notice water leakage around windows or doors? Can you feel warm air escaping when you stand near a slide-out? Is there frost forming on the inside of your windows or near plumbing fixtures? These are all indicators that cold air is getting in. The best time to prepare is in the fall, before the temperatures take a serious dip. I recommend inspecting areas people often forget, like attic vents, storm doors, and the seals around your gutters.
Cold Temperatures and Your Plumbing System
The single biggest risk to your RV during cold weather is your plumbing. Water expands when it freezes, and that expansion can wreak havoc on your entire system. I’ve seen it all: frozen pipes that crack, plastic plumbing fixtures that burst, and water connections that pop right off. The resulting water damage, often hidden behind walls and in cabinets, can be incredibly expensive and time-consuming to repair.
This is why a proper winterization service is so critical. When we winterize an RV, we follow a precise process to protect it. We start by completely draining all the fresh water from the system and then use compressed air to blow out any remaining droplets from the lines. Next, we add a special, non-toxic RV-safe antifreeze to the plumbing. We also make sure to protect the hot water tank by draining it and bypassing it so antifreeze doesn’t enter it. Finally, we check the furnace to ensure it’s functioning correctly for those chilly nights. Skipping these steps can cost you serious money down the road.
Preparing for Cold Climates When You Travel
Many of our renters are first-timers or seasonal travelers heading south for the winter. If you’re a snowbird, you might pass through colder regions on your way to warmer destinations. Even a late-fall camping trip can expose your RV to freezing temperatures. A few preparations can make your journey much safer and more comfortable.
First, insulate your windows to prevent warm air from escaping. You can use reflective foil insulation or heavy curtains. Next, get on the roof and check for missing shingles, gaps in the sealant, and debris like pine needles or leaves that can trap moisture. Snow and ice are heavy, and they can put a lot of stress on your roof, vents, and solar panels.
Also, pay close attention to your propane tank levels, as your furnace will be running more often. Understand how your electricity use might increase and set your furnace to a reasonable temperature to conserve energy while preventing pipes from freezing. For extended stays in the cold, consider using RV skirting and tank heaters to protect the underbelly and cover any exposed equipment.
Keep Warm Air Inside and Stop Heat Loss
Keeping your RV cozy is all about stopping heat from escaping. Simple upgrades can make a huge difference in saving energy and maintaining a comfortable temperature. Adding weatherstripping around doors and windows is an easy and effective fix. Cleaning your gutters prevents ice dams from forming, which can cause water to back up and seep into your roof.
Take the time to seal any openings around vents, plumbing lines, or electrical hookups. Use your thermostat wisely—set it to a consistent, moderate temperature instead of constantly adjusting it. On larger rigs, check your chimney and vent areas to ensure they are properly sealed. By managing airflow, you can ensure the warm air your furnace produces stays right where you need it. Also, be aware of early warning signs like drafts, a musty smell that could indicate mildew, or any unusual noises from your furnace.
Step-by-Step RV Winterization Process I Perform
When you trust Cozy Turtle with your RV, we treat it like our own. Our winterization process is thorough because we know how important it is to get it right. Here’s a look at what I do for every vehicle:
- Full exterior and roof inspection: I start with a complete visual check of the RV’s body and roof, looking for any signs of wear, damage, or potential vulnerabilities.
- Checking gutters and debris: I clear all gutters of leaves, pine needles, and other debris that could cause blockages and water damage.
- Draining the water system: I drain the fresh water tank, grey tank, black tank, and all water lines to remove every last drop of water.
- Protecting tanks: I make sure all holding tanks are properly emptied and prepared for the cold.
- Treating plumbing with RV antifreeze: I carefully pump RV-safe antifreeze through the entire plumbing system, including faucets, toilets, and showerheads.
- Inspecting furnace and ventilation: I check the furnace, propane tank, and all ventilation systems to ensure they are clean and in good working order.
- Covering components: I make sure all exterior components, like A/C units and vents, are covered and protected from the elements.
- Final check for leaks and drafts: Before I finish, I do one last walkthrough to look for any leaks, cracks, drafts, or openings that need to be sealed.
Common Issues That Happen When RVs Aren’t Winterized
I can’t stress this enough: neglecting winterization can lead to a long list of costly problems. The most common and destructive issue is pipes that freeze, crack, or burst. This leads directly to water leakage, which in turn causes mold and structural damage.
You’ll also experience significant heat loss, forcing you to use more electricity or propane to stay warm. The constant exposure to cold can also damage exterior vents and seals, making them brittle and prone to breaking. All of these issues lead to expensive repairs that could have been easily prevented with a little bit of preparation before the temperatures start dropping in October.
When to Schedule RV Winterization in Myrtle Beach
The ideal time to winterize your RV is in the late fall, just as the temperatures begin to consistently dip into the 40s at night. You should also schedule a service before you put your RV into long-term storage or if you plan to park it at a seasonal lot for the winter. If your travel plans involve heading north or through colder states, winterizing beforehand is a must.
Even here in Myrtle Beach, we get enough temperature swings to cause freezing. An unprotected RV is a gamble, and it only takes one cold snap to cause irreversible damage. It’s always better to be safe than sorry.
How to Store Your RV During the Winter
Proper storage is just as important as winterization. Before you park your RV for the season, give it a thorough cleaning inside and out. Remove all food, linens, and any other materials that might attract pests. Go through and check all attic vents, windows, openings, and doors to make sure they are securely closed and sealed.
If possible, cover your rig to protect it from outdoor debris, sun exposure, and moisture. If your RV will remain hooked up to power, it’s a good idea to run the furnace periodically to keep the interior dry. Finally, inspect it regularly for any signs of leaks, pest intrusion, or other damage. For easy and professional winterization before storage, you can use our simple Myrtle Beach winterization request form to get on the schedule.
