Icon 01402 Tandem Fender Skirt: Best Durable ABS

High-impact ABS plastic is the gold standard for travelers who frequent gravel roads or rough highway corridors. The Icon 01402 Tandem Fender Skirt utilizes this resilient material to absorb impacts that would easily crack or shatter cheaper factory replacements. A textured finish helps disguise minor scuffs and road rash, keeping the rig looking sharp even after thousands of miles.

This specific model features a structured, vacuum-formed design that resists UV degradation and extreme temperature swings. Travelers moving between desert heat and freezing mountain passes will appreciate how the plastic remains pliable rather than turning brittle. It measures 64.25 inches by 11.25 inches, making it a highly compatible choice for many dual-axle travel trailers.

If your tandem-axle trailer experiences heavy highway use and you want a skirt that will not warp under the blistering sun, this is your best option. It is not the cheapest guard on the market, but the structural integrity easily justifies the investment. Choose this model if you want a set-and-forget protective barrier that outperforms flimsy stock skirts.

RecPro Tandem Axle Fender Skirts: Best Tough Plastic

RecPro has earned a reputation for producing rugged, consumer-focused RV components, and these tandem axle fender skirts are no exception. Manufactured from incredibly tough, proprietary plastic, they are engineered to flex slightly under stress instead of snapping. This elasticity is crucial when navigating tight campsites where stray branches or high curbs present constant hazards.

The sleek, aerodynamic profiling not only looks modern but also helps channel air efficiently around the wheels. Many alternative models suffer from wind buffet at high speeds, which can loosen mounting screws over time. RecPro addresses this by reinforcing the mounting flange, distributing the physical stress of travel more evenly across the vehicle’s sidewall.

These skirts are ideal for those who prioritize structural flexibility and sleek aesthetics on a dual-axle setup. If you frequently tow your trailer through tight spaces or high-wind environments, these skirts offer the perfect balance of give and take. Skip this option if you have a single-axle setup, but buy them immediately if you need reliable, heavy-duty tandem protection.

Protecting an RV from road spray and gravel does not have to drain your travel fund. The JR Products 01155 Fender Boot offers a highly practical, cost-effective solution for budget-conscious RVers. This compact guard focuses on shielding the critical vulnerable spots directly behind the tires where rocks are most likely to strike.

Made from a durable polymer blend, it provides basic impact resistance and reliable UV protection without the premium price tag. Its compact footprint means installation is straightforward and requires minimal drilling or modification to the existing wheel well. It is an excellent choice for smaller trailers or vintage rigs where finding exact-fit full-length skirts is difficult.

For owners of class B motorhomes, camper vans, or tow vehicles that navigate harsh winter roads, this is the definitive protective upgrade. It provides a level of rugged, wraparound protection that standard flat guards simply cannot match. If your travel style includes muddy paths and winter highways, this heavy-duty flare belongs on your vehicle.

Husky Liners Custom Mud Guards: Best Heavy Duty

Some travel routes demand heavy-duty armor rather than simple plastic trim. Husky Liners Custom Mud Guards are built specifically for those punishing conditions where rocks, mud, and road grime are constant threats. Molded from a proprietary thermoplastic material, these guards are virtually indestructible and can survive impacts that would shatter standard skirts.

What sets these guards apart is their custom-molded design, which hugs the specific contours of your vehicle’s fenders for maximum coverage. This precise fit prevents debris from sneaking past the guard and damaging the delicate undercarriage or plumbing lines. The textured finish and minimalist styling ensure they blend seamlessly into the vehicle profile while working tirelessly behind the scenes.

If you frequently tow your camper down unpaved logging roads, washboard gravel, or through heavy construction zones, these are non-negotiable. They offer the absolute best defense against high-velocity stone chips and thick, sticky mud. Do not hesitate to invest in these if your adventures take you far off the beaten path.

Its clean, classic lines look right at home on a wide variety of trailer brands and models. By matching original styling, it preserves the aesthetic integrity of your trailer while providing modern material durability.

This fender is the ultimate choice for owners looking to replace cracked, yellowed, or missing factory guards without modifying their wheel wells. It offers an easy, reliable fit that makes your trailer look brand new again with very little effort. If hassle-free compatibility and authentic styling are your main priorities, this is the perfect match.

How to Measure Your RV Wheel Well for a Perfect Fit

Buying fender guards without taking precise measurements is a recipe for frustration and return shipping fees. RV manufacturers frequently change wheel well dimensions, even within the same model year, meaning online compatibility charts are not always foolproof. To get a perfect fit, you must measure the overall length, height, and width of the wheel opening yourself.

Start by measuring the absolute longest point of the opening from left to right, known as the overall length. Next, measure from the lowest point of the skirt to the highest peak of the arch to determine the overall height. Finally, measure the depth of the wheel well and the spacing between dual axles to ensure the guard’s contours line up perfectly with your tires.

Keep these key measurement points in mind before making your purchase:

• Overall length: Measure from the outer flange tip to tip.
• Overall height: Measure from the bottom edge to the topmost curve.
• Width of the mounting flange: Ensure there is enough surface area on the RV sidewall to secure the mounting screws.
• Axle spacing: Verify the distance between center hubs on tandem setups matches the guard’s wheel arch spacing.

Take these measurements twice to ensure absolute accuracy, and always check the placement of any pre-drilled holes on the new guard. If your existing screw holes do not line up, you may need to drill new ones in the guard or the RV body. Taking the time to measure correctly upfront saves hours of installation headaches later.

Step-by-Step Guide to Installing Your Fender Guards

Installing new fender guards is a highly satisfying DIY project that requires only basic hand tools and a bit of patience. Before beginning, gather a drill, self-tapping screws, silicone sealant, painter’s tape, and a level. Having a helper to hold the guard in place during the initial fitting will make the entire process significantly easier.

Begin by thoroughly cleaning the mounting surface on your RV to remove all road grime, old adhesive, and dirt. Hold the new fender guard up to the wheel well and secure it temporarily with painter’s tape to check the alignment. Use your level to ensure the guard sits straight, and mark the screw placement holes with a pencil.

Apply a small bead of high-quality exterior silicone sealant along the mounting flange where it meets the RV sidewall. This sealant acts as a crucial water barrier, preventing moisture from seeping behind the guard and causing wood rot or delamination. Carefully drive your self-tapping screws into the pre-marked holes, starting from the center and working your way outward.

Avoid overtightening the screws, as too much pressure can crack the plastic or strip the holes in the fiberglass sidewall. Once all screws are secure, wipe away any excess sealant that squeezed out from the edges. Allow the sealant to cure fully for 24 hours before taking your RV out on the road.

ABS Plastic vs. Fiberglass: Choosing the Best Material

Choosing between ABS plastic and fiberglass fender guards is one of the most important decisions you will face. Both materials offer distinct advantages, but they perform very differently under real-world travel conditions. Understanding these differences helps you select the material that matches your specific travel style and budget.

ABS plastic is highly popular because it is lightweight, affordable, and incredibly flexible. It can take direct hits from road debris and bend without snapping, making it ideal for rough terrain. However, lower-grade ABS can degrade and fade under constant UV exposure if it is not treated with UV inhibitors.

Fiberglass guards offer superior structural rigidity and a premium, high-gloss finish that can be painted to match your RV perfectly. They do not fade in the sun and maintain their shape beautifully over years of service. The tradeoff is that fiberglass is brittle; a direct impact from a heavy rock or blown tire can shatter it completely, and replacements are typically more expensive.

Ultimately, ABS plastic is the practical winner for off-roaders and high-mileage travelers who prioritize impact resistance and cost. Fiberglass is best suited for luxury coaches and park models where aesthetic appeal and long-term structural stability outweigh the risk of impact damage. Evaluate your typical travel destinations to make the right choice.

Maintenance Tips to Extend the Life of Your Fender

Even the most durable fender guards require routine maintenance to survive the harsh realities of the open road. Constant exposure to road salt, UV rays, and physical vibration will slowly wear down any material over time. Developing a quick inspection routine can help you catch minor issues before they turn into costly failures.

Wash your fender guards regularly with mild soap and water, avoiding harsh chemical cleaners that can strip away UV coatings. After cleaning, apply a high-quality UV protectant spray specifically designed for plastics or fiberglass to prevent fading and brittleness. This simple step acts as a sunscreen for your guards, significantly extending their lifespan.

Check the mounting screws and hardware after every long road trip to ensure nothing has vibrated loose. If you notice a loose screw, tighten it immediately, and replace any rusted hardware with stainless steel screws to prevent rust stains on your RV. Keep an eye out for tiny hairline cracks near the mounting holes, as these can spread quickly if left unaddressed.

If you do discover a small crack, you can stop it from spreading by drilling a tiny hole at the absolute end of the crack, a technique known as stop-drilling. Seal the crack with a flexible epoxy or plastic weld adhesive to restore structural integrity. Taking these proactive steps ensures your fender guards will continue protecting your rig for years to come.

Safeguarding your rig with the right fender guards is a small investment that yields massive returns in peace of mind and vehicle preservation. Choose the material and fit that matches your journey, install them with care, and keep exploring the open road with confidence.
