Why RV Fenders Are Vital for Long-Term Storage

When your RV sits stationary for months, the wheel wells become a prime target for moisture accumulation and unwanted wildlife. Without a sturdy fender skirt, road salt, debris, and water spray from nearby traffic can penetrate the exposed framing of your rig. Over time, this leads to hidden corrosion and structural decay that remains invisible until it’s far too late.

Beyond weather protection, fender skirts serve as a physical barrier against rodents and insects looking for a warm place to nest. A well-fitted fender seals off the gap between the tire and the body, effectively keeping pests out of your insulation and wiring. Think of them as the first line of defense for your mobile home’s integrity.

Preparing Your Wheel Wells for Fender Installation

Before slapping on new fenders, you must clear out the old debris and inspect the underlying frame for existing damage. Use a stiff brush to remove dirt and rust, then treat any exposed metal with a rust-inhibitor spray. Installing new plastic over a rotting frame is a recipe for disaster, so ensure the substrate is solid before you begin.

Check the condition of the existing sealant around the wheel well opening as well. If the old caulk is cracked or peeling, scrape it away entirely to ensure a clean, flush surface for the new fender. Taking these extra steps ensures your new fenders aren’t just covering up problems, but actively preventing them.

Icon Technologies ABS Plastic Fender Skirts

Icon Technologies is the industry standard for a reason, primarily because they focus on high-grade ABS plastic that resists UV degradation. If you own a popular RV model, they likely have a pre-molded shape that fits your rig perfectly without any cutting. This is the go-to choice for owners who want a "factory-fresh" look with minimal installation headaches.

Their plastic is thick enough to withstand minor impacts from road debris while remaining flexible enough to handle temperature fluctuations. If you value reliability and want a product that mimics the original build quality of your RV, Icon is your best bet. You’re paying for peace of mind, and for most, that’s worth every penny.

RecPro Universal RV Fender Skirts for Durability

RecPro’s universal options are a godsend for those with older or discontinued RV models where exact replacements are impossible to find. They are built for ruggedness, designed to handle the wear and tear of long-term storage in diverse climates. Because they are universal, you will need to do some light trimming, but the trade-off is a much more robust material.

If you aren’t afraid of a little DIY work, these skirts offer superior value for the money. They are ideal for the budget-conscious traveler who prioritizes function over form. If you need a heavy-duty solution that will last for years, RecPro is the brand that delivers the most value.

JR Products Fender Skirts: The Custom Fit Option

JR Products excels at providing specific, direct-fit replacements that feel like they were installed at the factory. They maintain an extensive catalog of shapes, making them the first place to look if you want to avoid the hassle of custom trimming. Their attention to mounting hole alignment is particularly impressive, saving you from drilling new holes in your RV’s sidewall.

If you’re looking for a seamless, stress-free installation, JR Products is the gold standard. They cater to the owner who wants the job done once and done right. While they might be slightly more expensive than universal alternatives, the time you save on installation makes them a smart investment.

Heng’s Industries RV Fender Skirt Replacements

Heng’s Industries has carved out a niche by producing durable, impact-resistant fender skirts that are widely available through most major RV retailers. They focus on longevity, utilizing materials that don’t become brittle after a few seasons of sun exposure. Their designs are straightforward, functional, and designed to fit a wide range of standard travel trailers.

Lippert Components OEM Style Fender Skirts

As one of the largest suppliers in the RV industry, Lippert Components offers fender skirts that are likely identical to what came on your rig from the dealership. Because they supply the original equipment, the fit and finish are usually spot-on. You aren’t guessing if the curves will line up—you are getting the intended design.

These are the best choice for owners who want to maintain the resale value of their RV by keeping it as close to original as possible. While they might be harder to source for very old rigs, they are the king of modern replacements. If you own a newer RV, stick with Lippert to ensure a perfect, stress-free fit.

AP Products Heavy-Duty Fender Flare Solutions

AP Products leans into the "heavy-duty" side of the market, offering fender solutions that are slightly thicker and more rigid than standard ABS options. These are perfect for RVs that see regular travel in harsh environments or off-road conditions where extra protection is required. Their mounting systems are also notably secure, ensuring the fender stays put even under high wind loads.

If you live in an area with extreme weather or you frequently take your rig on gravel roads, AP Products is the superior choice. They provide a level of structural reinforcement that lighter plastic skirts simply can’t match. You’ll appreciate the extra thickness every time you inspect your wheel wells after a long storage period.

Measuring Your RV for Correct Fender Fitment

Don’t rely on your RV’s year, make, and model alone; manufacturers often changed parts mid-production. Always measure the height, width, and arc of the wheel well opening manually before placing an order. Use a flexible measuring tape to capture the curve accurately, and note the placement of existing screw holes.

• Height: Measure from the bottom edge to the highest point of the arch.
• Width: Measure the span across the base of the opening.
• Projection: Note how far the fender needs to stick out from the body.

Taking these measurements ensures you won’t be dealing with the hassle of returns. A few minutes with a tape measure now prevents hours of frustration later.

Sealing and Securing Your New Storage Fenders

Once you’ve aligned your new fenders, use a high-quality, exterior-grade butyl tape or RV-specific sealant to create a watertight gasket. Never rely on screws alone to keep moisture out; the sealant is what actually protects your wall framing from rot. Apply a continuous bead around the perimeter for the best results.

When tightening your screws, be careful not to overtighten, as this can crack the plastic or strip the mounting holes. Use stainless steel screws with rubber washers to prevent corrosion and ensure a snug, vibration-resistant fit. Properly sealed fenders will keep your rig safe, dry, and pest-free for years of storage.

Protecting your RV’s wheel wells is a small investment that pays massive dividends in the longevity of your rig. By choosing the right material and ensuring a proper, sealed fit, you’re effectively insulating your investment against the elements. Take the time to measure correctly, seal thoroughly, and choose the fender that fits your specific needs to keep your home on wheels ready for the next adventure.
