This skirt is perfect for those who are nervous about cracking a rigid replacement during a self-installation project. It is also highly recommended for travelers who frequent freezing northern climates where standard plastics turn brittle. Avoid this model if the RV requires an incredibly rigid, structural panel to cover up loose insulation, as this skirt is designed to bend rather than support heavy weight.

Icon 12210 Polar White Skirt: Best Sleek Look

The truth is, utility does not have to look industrial or dated. The Icon 12210 Polar White Skirt is designed for RV owners who refuse to compromise on their rig’s curb appeal. Featuring a brilliant, clean polar white finish and a streamlined silhouette, this skirt instantly modernizes the profile of any compatible fifth-wheel or travel trailer.

At 65 inches in length, this tandem skirt features a smooth, glossy surface that is incredibly easy to clean and polish. The high-quality finish resists yellowing from sun exposure, ensuring the RV looks sharp even after years of direct exposure to intense UV rays. Its aerodynamic curves not only look premium but also help channel airflow smoothly around the spinning tires to minimize drag.

This is the absolute best option for owners of modern, white fifth-wheels who want to maintain a sleek, clean, high-end appearance. If pride in having the sharpest-looking rig in the campground is a priority, this skirt will deliver that visual polish. Do not purchase this if the RV has a cream, grey, or custom-painted lower trim, as the bright polar white will clash dramatically with the existing color scheme.

How to Measure Your RV for the Perfect Fit

Buying a fender skirt based on the RV’s model name alone is a recipe for returns and frustration. Manufacturers frequently change dimensions mid-year or use different trim packages on the same model. To avoid this headache, you must take precise physical measurements of your existing skirt or the empty wheel well before browsing online catalogs.

Start by securing a flexible tape measure and a notepad, then measure the following key dimensions:

• Overall Length: Measure from the absolute farthest left edge to the farthest right edge of the skirt.
• Overall Height: Measure from the lowest dangling point to the highest peak of the fender.
• Wheel Well Width: Measure the interior opening where the tires sit to ensure proper clearance.
• Screw Hole Centers: Note the distance between mounting holes if you hope to reuse the factory mounting locations.

Always check for asymmetrical designs, as some skirts taper significantly on one side to accommodate slide-outs or steps. If the original skirt is missing entirely, trace the outline of the wheel well opening onto a large piece of cardboard. This template can be used to compare dimensions against online schematic drawings to guarantee a flush fit against your trailer’s siding.

Keep in mind that minor discrepancies of less than a quarter-inch can often be absorbed by the flexibility of ABS plastic. However, trying to force a skirt that is an inch too short will create tension that leads to immediate failure. Invest the time up front to measure twice, and you will save hours of frustration during the installation phase.

Step-by-Step Guide to Installing Fender Skirts

Installing a new fender skirt is a straightforward DIY task, but rushing the process can ruin your brand-new plastic. Start by removing the old skirt and thoroughly cleaning the mounting area with rubbing alcohol to remove old sealant, road grime, and adhesive. Inspect the underlying wall structure for water damage or loose screws that must be repaired before attaching the new skirt.

Follow these steps to ensure a secure, rattle-free installation:

• Dry Fit: Tape the new skirt into place using painter’s tape to verify alignment and tire clearance.
• Pre-Drill Holes: Use a drill bit slightly smaller than your mounting screws to pre-drill the plastic, preventing splitting.
• Apply Sealant: Put a small dab of butyl tape or exterior RV sealant behind each screw hole to prevent water intrusion.
• Secure Gradually: Drive the screws in slowly, starting from the center and working your way outward to prevent warping.

Never over-tighten the mounting screws, as ABS plastic requires a small amount of wiggle room to expand and contract in hot weather. If you clamp the screws down too tightly, the plastic will buckle or crack around the screw heads during your first hot summer day. Secure them until they are snug, then back them off a quarter-turn for the perfect hold.

For trailers with thin fiberglass or aluminum siding, consider adding a backer strip behind the wall. A thin strip of aluminum or wood behind the mounting surface gives the screws something substantial to bite into. This prevents the screws from stripping out of the thin siding when subjected to heavy highway crosswinds.

Tips to Keep Flexible ABS Plastic from Cracking

UV radiation and highway vibrations are the twin silent killers of flexible ABS fender skirts. Over time, sunlight breaks down the chemical bonds in the plastic, turning it brittle and highly susceptible to cracking from minor impacts. Combining regular preventative maintenance with smart road habits is the only way to maximize the lifespan of your investment.

To extend the life of your skirts, incorporate these simple care strategies into your RV maintenance routine:

• Apply UV Blockers: Treat your skirts twice a year with a high-quality UV-protectant spray designed specifically for automotive plastics.
• Use Rubber Washers: Place small rubber washers between the screw heads and the plastic to absorb road vibrations and distribute pressure.
• Mind the Temperature: Avoid washing or flexing your fender skirts in freezing temperatures when the plastic is at its most brittle.

When parking your RV for extended storage, try to position the rig so the tires and fenders are shielded from direct afternoon sun. If shade is unavailable, consider using affordable wheel and fender covers. These simple shields block destructive ultraviolet rays, keeping your flexible ABS pliable and crack-free for years to come.

Why Flexible Fender Skirts Beat Rigid Options

Many RV owners assume that a completely rigid fender skirt is superior because it feels stronger to the touch. This is a common misconception that often leads to shattered plastic on the highway. Rigidity breeds brittleness; when a stiff skirt is hit by a rock thrown from a tire, it has no way to absorb the energy and immediately cracks or shatters.

RVs are essentially rolling earthquakes, subjected to constant twisting, flexing, and shaking as they travel down the highway. A flexible ABS skirt can bend and twist in unison with the trailer’s sidewalls without stress-fracturing. This dynamic adaptability prevents the mounting holes from slowly wallowing out and stripping over time, keeping your skirt firmly attached.

Temperature fluctuations also favor flexible options, as they accommodate the thermal expansion and contraction of your RV’s aluminum or fiberglass siding. Choosing a flexible skirt ensures your rig remains aerodynamic, protected, and visually appealing through every climate. Ultimately, flexibility translates directly to longevity on the open road.

Finding the perfect balance between style, durability, and flexibility is the key to choosing the right RV fender skirt. By taking accurate measurements and opting for high-quality ABS materials, you can safeguard your trailer from road hazards while keeping it looking its best. Invest in the right fit today, and enjoy peace of mind on all your upcoming journeys.
