Why RV Skirting is a Winter Camping Essential
The magic of RV skirting lies in a simple principle: creating a pocket of trapped, or "dead," air. This unmoving air underneath your rig acts as a buffer between the cold ground and your RV’s floor. Think of it like a double-pane window for your entire underbelly; the air gap is the insulation.
This trapped air provides two critical benefits. First, it prevents your holding tanks, water lines, and sewer connections from freezing solid, a catastrophic and expensive failure. Second, it stops the cold from seeping up through the floor, which is often one of the least insulated parts of an RV. Your furnace won’t have to work nearly as hard to maintain a comfortable temperature inside.
The result is more than just warmth. You’ll use significantly less propane or electricity, saving you real money over a long winter. It also stabilizes the interior temperature, eliminating those cold spots on the floor and making your living space far more comfortable and consistent.
RV Skirting Direct: Custom-Fit Vinyl Protection
When you want a perfect, professional fit without any of the guesswork, a custom-made vinyl skirt is the gold standard. Companies like RV Skirting Direct specialize in creating skirts tailored precisely to your rig’s make, model, and year. They account for every slide-out, stair, and hitch, ensuring a tight, draft-free seal.
The material is typically a heavy-duty, marine-grade vinyl that’s built to withstand brutal sun, wind, and snow for years. Installation involves a track system or high-quality snaps attached to the RV, allowing for a taut, clean look. This isn’t a flimsy tarp; it’s a purpose-built, insulated wall for your RV’s underbelly.
The tradeoff for this perfect fit is cost and lead time. This is a premium solution, and you’re paying for the custom labor and high-quality materials. But for a full-timer who plans to stay put for an entire season, the investment pays for itself in energy savings and peace of mind.
AirSkirts: The Easiest Inflatable Skirt Setup
For the RVer who moves frequently, the idea of installing and removing dozens of snaps or panels is a non-starter. This is where AirSkirts completely changes the game. Their system uses durable, inflatable tubes that you simply place under the edge of your rig and inflate with the included pump.
The genius of this system is its simplicity and lack of permanent modification. There is no drilling, no snaps, and no adhesive. The inflated tubes create a surprisingly effective seal by pressing firmly against the ground and the RV’s chassis. Setup and breakdown take minutes, not hours, making it a practical solution for weekend trips or for those who change locations every few weeks.
While incredibly convenient, the R-value of trapped air in a tube may be slightly less than a thick insulated vinyl or foam board. The initial cost is also significant, comparable to some custom vinyl options. However, if your top priorities are speed, portability, and protecting your RV’s resale value by avoiding modifications, AirSkirts is in a class of its own.
EZ Snap Skirting: Top Choice for DIY Installation
Protect your RV with this easy-to-install skirting kit. The no-drill fastener system and durable, non-fray Diamond Weave fabric provide all-weather protection and a custom fit for travel trailers up to 35 feet.
EZ Snap bridges the gap between a fully custom job and a from-scratch DIY project. It’s designed for the RVer who is comfortable with a tape measure and a utility knife and wants a professional look for a fraction of the cost. You order the skirting material and the proprietary fasteners, then cut and assemble it yourself.
The DEWALT Atomic Compact 30 ft. Tape Measure offers a 13 ft. max reach for straighter, stronger measurements. Its 20% more compact grip enhances ergonomics and control, while the integrated finger brake provides superior blade management.
The key innovation is the fastening system. Instead of traditional snaps that require drilling into your RV’s fiberglass, EZ Snap uses screw-in studs with a 3M VHB adhesive backing. This creates an incredibly strong bond without permanent holes, which is a huge plus for many owners. The process involves sticking the fastener bases to the RV, cutting the vinyl to size, and snapping it all into place.
This approach offers tremendous value, but it demands patience and precision. Measure twice, cut once is the rule here, as a mistake means wasted material. For those willing to put in the work, the result is a custom-fit, high-quality skirt that looks and performs like a professionally installed product.
RecPro Vinyl Skirting: A Durable, All-Weather Kit
Protect your mobile home with this 10-pack of white vinyl skirting panels. Each panel measures 16" W x 35" L, providing durable and weather-resistant protection for your home's foundation.
RecPro is a trusted name in the RV parts world, and their vinyl skirting kits are a solid, reliable choice. Unlike a fully custom service, RecPro provides a standardized kit with long rolls of heavy-duty, cold-crack-rated vinyl and the necessary hardware. It’s a workhorse solution that prioritizes durability over a bespoke fit.
These kits typically come with either a J-rail channel system or standard twist-lock fasteners and snaps that you install yourself. This requires drilling and a bit more installation know-how than an adhesive-based system like EZ Snap. The material is tough and designed to handle harsh winter conditions without becoming brittle.
Think of this as the middle-ground option. It’s more robust and professional than a basic tarp or hay bale solution, but more affordable than a fully custom or inflatable skirt. It’s a great fit for the RVer who is stationary for the season and wants a durable, no-nonsense skirt they can install themselves.
Owens Corning Foamular: The Rigid Foam DIY Method
Create with confidence using this 12-pack of pink XPS foam boards. Each 15" x 7.5" x 1/2" sheet offers a durable, crumble-resistant surface perfect for sculpting, model making, and floral arrangements.
For the ultimate in insulation value on a budget, nothing beats the rigid foam board method. Using 1.5-inch or 2-inch thick sheets of XPS foam (like Owens Corning Foamular or similar brands) provides an R-value of R-7.5 to R-10, far exceeding most fabric skirts. This is the go-to for stationary RVers in extremely cold climates where performance is the only thing that matters.
The process is straightforward: measure the sections under your RV and cut the foam boards to fit snugly. The pieces are wedged between the ground and the RV frame, and the seams are sealed with high-quality foil tape to create a continuous, airtight barrier. It’s simple, effective, and incredibly cost-efficient.
The downsides are obvious. The foam boards are bulky to transport and store, making this a poor choice for anyone who moves often. It can also be damaged by high winds if not properly secured, and the bright pink or blue aesthetic isn’t for everyone. But if your goal is maximum heat retention for minimum cost, this DIY method is unbeatable.
Skirt-All Panels: A Robust, Long-Term Solution
If you’re setting up an RV or park model for long-term or even permanent living, you might want something that feels less temporary. Skirt-All and similar panel-based systems offer a residential-style solution. These are interlocking, insulated panels made from durable plastics or composites that create a hard, protective wall around the base of your rig.
Installation is more involved than any other method, often requiring a level ground surface and sometimes a simple frame. Once installed, however, these panels are incredibly robust. They offer excellent insulation, stand up to wind and weather with ease, and provide a clean, finished look that elevates the appearance of a stationary RV. Many systems also include vented panels to prevent moisture buildup.
This is the most expensive and least portable option on the list. It’s an investment in turning your RV site into a more permanent homestead. For full-timers who own their lot or have a multi-year lease, these panel systems provide unmatched durability, security, and long-term performance.
Maximizing Heat Retention with Proper Installation
The best skirting material in the world won’t do its job if it’s installed poorly. The entire goal is to stop air movement, so a tight seal at both the top (against the RV) and the bottom (against the ground) is non-negotiable. Even small gaps can create a draft that negates the insulating effect of the trapped air.
For any type of fabric or vinyl skirt, make sure the bottom edge has enough extra material to lie flat on the ground. Use sandbags, rocks, or even packed snow to hold it down firmly and seal any gaps caused by uneven terrain. For rigid foam or panel systems, use foil tape to seal every seam between panels meticulously. Don’t forget to create a sealed, insulated access panel for your sewer and water connections.
For an extra layer of protection in deep-freeze conditions, consider placing a small, thermostatically controlled heat source inside the skirted area. A simple 60-watt utility bulb or a small, oil-filled radiator set to its lowest setting can be enough to keep the temperature under your rig just above freezing. This turns your entire underbelly into a small, conditioned space, providing the ultimate defense for your tanks and pipes.
Choosing the right RV skirt is about matching the solution to your lifestyle—your budget, how often you move, and how much work you’re willing to do. It’s not just an accessory; it’s a critical system that makes four-season RV living comfortable, safe, and affordable. By blocking the wind and trapping a layer of air, you transform your rig from a vehicle into a well-insulated, year-round home.
