Free Guide to Replacing Your RV Awning

Understanding RV Awning Basics and When Replacement Is Needed

An RV awning is a retractable or permanent fabric canopy that extends from the side of your motorhome or travel trailer. It provides shade, reduces interior heat buildup, and creates an outdoor living space. Most RV awnings use a motorized mechanism that rolls the fabric in and out along aluminum arms and a rail system mounted to the RV's exterior wall.

RV awnings typically last between 5 and 15 years, depending on climate, usage frequency, and maintenance. The fabric itself degrades from UV exposure, water damage, mildew, and general wear. Signs that your awning needs replacement include visible tears or holes in the fabric, metal arms that no longer retract smoothly, rust on the aluminum frame, fabric that no longer repels water, or a motor that makes grinding sounds without extending or retracting.

The most common type is the motorized roll-out awning, which uses a motor and switch to extend and retract. Standalone awnings are less common on modern RVs but may be found on older models or used as additions. Manual crank awnings require hand-cranking to extend and retract. Understanding which type you have is the first step in replacement because different styles have different installation requirements and costs.

Geographic location matters significantly. Awnings in sunny climates like Arizona or Florida deteriorate faster than those in areas with moderate sun exposure. High-wind regions cause more mechanical stress on the arms and motor. RVs stored outdoors year-round experience faster degradation than those stored in covered facilities. If your RV spends winters in snow or ice, water can pool on the fabric and cause damage if the awning is deployed in freezing temperatures.

Takeaway: Before shopping for a replacement, document your current awning's condition with photos, measure the length of your RV's wall where the awning is mounted, note whether your awning is motorized or manual, and keep your RV's model and year information handy.

Measuring Your RV and Choosing the Right Awning Size

Accurate measurements are essential for ordering a replacement awning that fits properly. The two critical measurements are the mounting length and the projection distance. The mounting length is how far the awning rail extends along your RV's wall—this determines the width of fabric you need. The projection distance is how far the awning extends outward from your RV when fully deployed—this typically ranges from 8 to 18 feet depending on the model.

To measure the mounting length, locate the brackets where your current awning attaches to the RV. If you still have the existing awning, measure from the center of the front bracket to the center of the back bracket. If the awning is already removed, measure the length of the rail that remains mounted on the RV's exterior. Take measurements at several points along the rail because RV walls are sometimes not perfectly straight. Most awnings come in standard lengths: 12, 14, 16, 18, 20, and 22 feet. Your measurement should match or be very close to one of these standard sizes.

The projection distance is less critical for replacement because most replacement awnings come with adjustable arms. However, knowing your current projection helps you understand what to expect. Longer projections provide more shade but increase wind resistance and mechanical stress. Most RV awnings project 8 to 12 feet when fully extended. If you're in a windy area, you may want a model rated for higher wind speeds even if it means slightly less projection.

Check your RV's manual or contact the manufacturer to confirm specifications. Many RV manufacturers list awning dimensions in their technical documentation. If you cannot find your specifications, contact RV dealers that specialize in your RV brand—they have access to factory specifications and can cross-reference your RV's model year and floor plan. Bringing your RV's VIN (Vehicle Identification Number) to a dealer helps them identify the exact awning configuration that came from the factory.

Takeaway: Write down your exact mounting length measurement and take a photo of your RV's side wall showing the awning location. These measurements are needed before contacting suppliers or ordering parts.

Comparing Replacement Awning Options and Brands

The RV awning market includes several established manufacturers, each with different price points, quality levels, and features. Dometic (formerly Carefree) and Lippert Components are the two largest manufacturers, supplying awnings to RV factories and aftermarket retailers. Both offer motorized and manual options across various price ranges. Dometic's products typically range from budget-friendly to premium, while Lippert also serves multiple market segments.

When comparing awnings, consider the fabric type and material. Traditional acrylic fabric is durable and resists mildew but may fade over time with UV exposure. Solution-dyed fabrics maintain color better. Some awnings use vinyl instead of acrylic, which resists water better but may be less breathable. The fabric thickness is measured in ounces per square yard—heavier fabrics (16 oz or more) last longer than lighter ones. Darker colors absorb more heat but hide dirt better; lighter colors reflect more heat but show stains more easily.

The roller tube—the mechanism that holds and extends the fabric—comes in different styles. Aluminum roller tubes are standard and affordable. Some premium models use stainless steel components for corrosion resistance, which matters if your RV is near saltwater or in humid climates. The motor quality varies significantly. Basic motors may be sufficient for casual users, but frequent users or people in windy climates benefit from stronger motors with better torque and faster retraction speeds.

Aftermarket awnings generally cost between $800 and $2,500 depending on size, quality, and motorization. Budget options start around $600 to $1,000 and work for light recreational use. Mid-range options ($1,000 to $1,800) offer better durability and features. Premium options ($1,800 and up) include reinforced frames, quieter motors, weather-resistant fabrics, and longer warranties. Online retailers, RV supply stores, and camping dealerships all stock awnings. Prices vary significantly between retailers for the same product, so comparing quotes is worthwhile.

Takeaway: List the features most important to you (motorized vs. manual, color preference, durability priorities) and use that to narrow down brand and model options within your budget range.

Tools, Materials, and Safety Preparation for Installation

Replacing an RV awning is a mechanical project that requires specific tools and careful preparation. Most DIY installations can be completed with standard hand tools and some specialized items. You will need a power drill with screwdriver and drill bits, an adjustable wrench set, Allen wrenches (hex keys) in various sizes, a tape measure, a level, a socket set, a step ladder or extension ladder, a caulking gun, and a helper—awning replacement should never be attempted alone because the components are awkward to handle.

Additional materials include marine-grade silicone sealant or RV caulk (to seal the mounting brackets), a wire brush or steel wool for cleaning corrosion from existing brackets, and replacement hardware if the new awning comes with different bracket designs. Many awning kits include brackets, fasteners, and a motor if motorized, but you should verify the contents before starting work. Have a flashlight or work light because mounting brackets may be in shaded areas under the RV overhang.

Safety preparation is critical. RV awning work involves working at height, handling heavy components, and working near the RV's electrical system if the awning is motorized. Before starting, inform anyone else nearby that you will be working above the area below the RV. Keep children and pets away from the work area. Wear work gloves, closed-toe shoes, and safety glasses. If removing an old motorized awning, disconnect the battery or locate the circuit breaker that controls the awning motor to prevent accidental activation.

Inspect the mounting surface on your RV's exterior wall before installation. Look for cracks, water damage, rust, or soft spots in aluminum. If you find water damage or soft spots, the underlying structure may need repair before the new awning is installed. Check that the area is clean and free of old caulk, dirt, or corrosion. The mounting surface must be solid because the awning brackets transfer the entire weight and wind stress to this point. If the wall is damaged, contact an RV repair specialist before proceeding.
