The Top 5 Best Options for Skirting for Trailers (Plus the 3 we’d NEVER recommend!)

If you’ll be living in an RV during the cold winter months, you’ve probably started to think about options for skirting. Skirting for trailers is crucial to block out cold air and keep your camper warm during the winter.

So how do you skirt an RV? We’ll share the most popular options, what to avoid, and how much you’ll need to budget. Let’s get started by first explaining why this extra step and added cost of RV skirting is worth it.

Why is skirting for trailers important?

Standard skirting from

While trailers are meant to live outside, it doesn’t mean they are immune to the harsh conditions of winter. Skirting your RV can protect valuable systems and is necessary for anyone living in an RV through the cold season.

The first benefit of skirting is that it will reduce draftiness in your RV. Skirting will prevent cold winds from blowing under your RV and trap warmer air inside. If your RV floors feel cold, skirting can help prevent heat loss and keep you from needing to run your heater.

The second benefit of skirting is protecting your water-related systems. If you’re living in an RV and will need to use hoses and tanks, skirting can keep the undercarriage of your RV warmer and protect these systems from freezing.

But the biggest benefit to skirting for trailers is that it can save you on the cost of electricity and propane needed to warm up your RV on a cold winter night. While some skirting options are expensive, you can balance out these costs by saving on your heating bills.

Skirting Options for RVs

There are many different materials we see recommended for skirting your trailer, but not all skirts are created equal! There are a few we recommend avoiding.

What Not to Use

1. Hay bales or Straw

Hay bales or straw are commonly recommended as the cheapest way to skirt a trailer. However, these options will attract unwanted rodents. Additionally, it’s a major fire hazard. Wet hay can literally “spontaneously combust!” We do not recommend considering this path.

2. Bricks or Cinderblocks

Stacking bricks or cinderblocks is another common recommendation for trailer skirting. However, unless you have masonry skills, it’s difficult to seal bricks properly to fully cut off airflow. Any gaps or holes left visible in the blocks or bricks will attract mice.

Plus, bricks or cinderblocks are a more permanent option and would make moving a trailer or accessing the undercarriage of an RV very difficult.

3. Particle board or Plywood

Plywood is an attractive option for RV skirting that is also very affordable. It’s most commonly used for people who live in trailers and never intend to travel.

However, if you’re in an area with lots of rain or snow, moisture will slowly deteriorate the wood. Moisture in an RV can cause serious damage, so a moisture-wicking material will be a better option.

Best Trailer Skirting Options

1. Foam Board Skirting

Foam board skirting is one of the least expensive options for RV skirting and is also highly effective. On a budget, this is the option we recommend.

Foam board can be purchased at your local hardware store (or at Home Depot or Lowes) and it’s inexpensive. Take your measurements for the parts of your trailer you want to skirt before heading off for supplies. The biggest thing to remember as you measure is if you’d like any parts of your undercarriage to be accessible. Pipe or tank access might mean cutting custom sections to allow for maintenance and use.

To get an idea of what this project entails, check out our tutorial video:

This will be a DIY project and will make the better part of a weekend to install, so it’s best to plan on completing this project before the end of October when below-freezing temperatures will make it difficult to adhere the tape.

For a full list of materials needed, costs involved, and how to complete this project on your own, check out our full tutorial on how to create your own foam board skirting (for about $100) here.

The biggest con to foam board skirting is the environmental impact. Foam board cannot be easily recycled and if you transport your RV, it can be difficult or impossible to pack up and reinstall at your next location.

But if you’re planning to keep your trailer in one place, foam board is durable to last multiple seasons and can even help keep your RV cooler in the summer.

2. Vinyl Skirting

There are multiple approaches to vinyl skirting: professionally installed kits, self-installed custom kits, and a DIY option. All will effectively seal off your RV and keep your RV warmer, but each has its pros and cons.

Professional Custom Vinyl Skirting

For professionally created and installed RV skirting, you’ll want to look at companies like,,, or Because these companies install the skirting themselves, you’ll need to be located near them, willing to travel, or find a local skirting company. Just Google search “custom RV skirting near me” to find options.

Insulated skirting from

These professionally installed kits typically start around $1,500, making it one of the most expensive skirting options.

Being professionally created and installed also means your skirt will be easier to remove and reuse year after year and there’s less of a risk of damage to your RV during installation. The high cost may be worth it if you regularly move your trailer or even just move it seasonally. With the custom option, you can also guarantee access to which part of the trailer you may need to use throughout the winter.

These high-end skirts will be the most attractive, so you shouldn’t hear any pushback from RV parks about your RV skirting. Some parks can be peculiar about approving or allowing only certain types of skirts!

It may be expensive, but it can save you hours of labor and hold up for years to come, which may justify the cost.

To learn more about this option and get a quote, we recommend starting with The Skirting Co.

Self-Installed Custom Vinyl Skirting Kits

For this option, look at companies like EZ Snap Skirting or The Skirting Co. These companies will ship you the supplies you need to install the skirting on your RV.

This is a great way to avoid the stress, hassle, and risk of having to figure out everything on your own, and a good middle-of-the-road price point. These skirting experts know the process and will support you to make sure you end up with a successfully insulated RV.

However, you’ll still need to shoulder installing the skirting yourself which can take a significant amount of time. Plus these kits will still cost you around $1,000 to start.

These two companies have two different approaches to consider as well. EZ Snap Skirting will send you the materials, but much of the measuring and cutting is still left up to you.

With a business like The Skirting Co. which only installs within a 250-mile radius of their shop in Indiana, you can order the same professional kit but install it yourself no matter where you’re located. Everything is already measured and cut for you, making the process simpler even though you’ll do much of the work yourself.

DIY Vinyl Skirting for Trailers

DIY vinyl skirting can be very affordable and costs only a couple hundred dollars for a large RV.

How We Made DIY RV Skirting from Billboard Vinyl hung with grommets and adhesive hooks for around $200

For DIY vinyl skirting, you can find old billboards and recycle them into your RV skirting. Check out this article for a full tutorial on how RVer Ashley Mann turned an old Cracker Barrel billboard into skirting for her home.

When discussing the best way to skirt her RV, Ashley shared that while this DIY approach was affordable, it was also challenging.

“It’s a lot of work—not just physical work, but mental work—figuring out exactly what sizes and shapes of vinyl to order to fit around all of the slide-outs and areas of different heights. It’s easy to make mistakes when measuring and cutting that can end up being costly if you have to order more material and pay shipping charges again…don’t ask me how I know!”

Ashley shared that she created DIY vinyl skirting for her RV twice and paid around $500 total. In addition to the long hours it took to create her own skirting, the vinyl did not make it through the season and needed to be redone year after year. This is another pro for professional skirting, which can be of better quality and durability.

There are pros and cons to each type of skirting for trailers. If you opt for the DIY vinyl skirting, this tutorial will help you gather all of the tools and supplies you’ll need.

3. Insulated Tarps

Similar to DIY vinyl skirting, insulated tarps would be highly effective at trapping heat and keeping your camper warm.

  • Reinforced: Tent footprint is equipped with 10 rust proof grommets. Double layer corner tech and heavy duty security stiching to ensure strength and superior quality.

However, insulated tarps are more expensive than vinyl, which can handle cold temperatures well on its own. Vinyl is a good option for below-freezing temperatures, but if you’re frequently encountering temperatures below 0º Fahrenheit, you may want additional insulation or even a heater.

4. Reflectix

Ever popular for keeping the sun out of camper windows, Reflectix is an option for RV skirting. The reflective material will reflect heat back into the undercarriage of your RV and block wind.

But Reflectix also tears easily and can be more easily punctured than foam board or vinyl. Reflectix also may not be allowed in RV parks because of how reflective it is. (Check with the front office before installing any type of RV skirting to make sure the property manager will allow your chosen type of skirting before you purchase everything!)

You would need quite a few panels of Reflectix to completely enclose a large trailer, so this can be a more costly option as well.

5. Inflatable Skirting (for Travelers!)

This last option is best for travelers. None of the above listed skirting options are conducive to someone who is actively traveling in an RV. In fact for many years, there were no travel skirting options.

But a recent player in the game came up with an inflatable trailer skirt called AirSkirts. These inflatable skirts are made of heavy-duty, puncture-resistant vinyl that takes the shape of your trailer as it’s inflated. You inflate the skirting with electrical pumps and the product will conform around the space under your RV, protecting pipes and trapping heat.

Because of this process, the skirt is held in place from the pressure of the RV. This means no tools are needed and you won’t be drilling or adhering anything into the frame of your RV. Breaking out the power tools or even heavy-duty adhesives can be stressful and lead to damage (especially if you go the DIY route). Avoiding that hassle and potential damage easily makes AirSkirts the least invasive skirting option.

AirSkirts can be the most expensive option on this list. However, if your RV needs to travel regularly throughout the winter, this is the best and only realistic option for skirting.

You can find an AirSkirt to fit your particular brand and type of RV on their website here.

The Best Skirting for Trailers

Based on cost alone, foam board skirting is the clear winner. However, the measuring, cutting, and installation labor can take days of work.

To save yourself time and hassle, choosing an AirSkirt or a professionally installed vinyl skirt can make sure no damage hurts your RV.

And if you’re traveling, there’s only one reliable option: an AirSkirt.
