We have all been there, sitting under a tattered, leaking awning while trying to enjoy a weekend at the campsite. A worn-out canopy doesn’t just look bad; it fails to protect your rig’s interior from the sun and rain.
Learning how to change rv awning fabric is a rite of passage for any serious DIYer or off-road enthusiast who takes their gear seriously. This project might seem intimidating due to the high-tension springs involved, but with the right approach, you can handle it safely.
In this guide, we will walk you through the entire process, from choosing the right material to safely winding the torsion springs. You will gain the confidence to refresh your RV’s look and functionality without paying a shop hundreds of dollars in labor.
Essential Tools and Materials for the Job
Before you climb a ladder, you need to gather the right gear to ensure the job goes smoothly. Having your tools organized prevents frustration and helps you maintain focus on the safety-critical steps of the installation.
Most modern RV awnings use a torsion spring system housed inside a metal roller tube. You will need tools that can grip and hold these springs under pressure, as well as basic hand tools for the hardware.
- Two sturdy ladders: You will need a partner for this job, and both of you need a stable platform to work from.
- Locking pliers (Vice-Grips): These are essential for holding the torsion rod while you remove the end caps.
- Cordless drill and a pop rivet gun: Many awnings are secured with rivets that must be drilled out and replaced.
- Silicone spray lubricant: This makes sliding the new fabric into the metal rail much easier.
- Flathead and Phillips screwdrivers: For removing the various screws on the arm assemblies.
- Permanent marker and masking tape: Use these to mark the position of the old fabric and the direction of the spring wind.
Choosing the Right Replacement Fabric
When selecting your new material, you generally have two choices: vinyl or acrylic. Vinyl is the most common choice for off-roaders because it is waterproof and very easy to clean after a muddy trip.
Acrylic is a woven fabric that breathes better, making it cooler underneath in extreme heat. However, it is not 100% waterproof and can be more expensive than standard vinyl replacements.
Ensure you measure your old fabric or the center-to-center distance of the awning arms before ordering. Getting the size right is the most important step in the entire preparation phase.
Safety First: Managing Torsion Spring Tension
The most dangerous part of learning how to change rv awning fabric is dealing with the springs. These springs are under a massive amount of tension to help the awning retract quickly and tightly.
If you release the tension haphazardly, the awning arm or the winding tool can spin out of control. This can cause serious injury to your hands or face, or damage the side of your RV.
Always work with a partner who can help stabilize the roller tube while you manage the tension. Never attempt to “eyeball” the spring count; always count the exact number of rotations as you unwind them.
Locking the Springs Before Disassembly
Before you remove the roller tube from the arms, you must lock the springs in place. Most technicians use a cotter pin or a heavy-duty nail inserted through the hole in the end cap.
If your model doesn’t have a locking hole, you will use your locking pliers to hold the torsion rod firmly. Do not let go of the pliers until the tension is fully released or the spring is securely pinned.
Take a moment to mark which way the spring is wound with your marker. This ensures that when you reassemble everything, you wind it in the correct direction to retract the fabric.
Step-by-Step Instructions on How to Change RV Awning Fabric
Once you have secured the springs and gathered your tools, it is time to get to work. Start by extending the awning about a foot and then locking the arms so they cannot move unexpectedly.
Remove the screws or rivets that secure the fabric to the awning rail on the side of the RV. These are usually located at the very ends of the rail to prevent the fabric from sliding during travel.
Next, you will need to disconnect the roller tube from the awning arms. This usually involves removing a bolt at the top of each arm while your partner supports the weight of the tube.
- Unwind the springs: Use your locking pliers to grip the torsion rod, remove the pin, and slowly count the turns as you unwind. Write this number down!
- Slide the old fabric out: With the tension gone, slide the old fabric out of the roller tube grooves and the RV’s wall rail.
- Clean the channels: Use a stiff brush and some soapy water to clean the polycord channels in the roller tube. Dirt and debris here will make sliding the new fabric in nearly impossible.
- Prep the new fabric: Lay the new fabric out on a clean tarp. Spray the polycord (the plastic bead at the edge) with silicone lubricant to help it glide.
- Install the new material: With one person on each ladder, slide the new fabric into the roller tube first, then guide it into the rail on the RV wall.
Aligning the Fabric Perfectly
Alignment is critical for a smooth roll-up. Once the fabric is in the rail, center it perfectly between the two awning arms using your previous marks as a guide.
If the fabric is off-center, it will telescope or bunch up at one end when you try to retract it. This puts uneven stress on the motor or springs and can lead to premature tearing.
Once centered, re-install the set screws into the awning rail on the RV wall. This locks the fabric in place so it cannot shift while you are driving down the highway or off-road trails.
Re-tensioning the Springs and Final Assembly
Now that the fabric is installed, you must put the tension back into the springs. Refer to the notes you made earlier regarding the number of turns and the direction of the wind.
Typically, an 8-foot awning requires about 8 to 10 turns, while larger 20-foot awnings might require 15 or more. Consult your specific manufacturer’s manual for the exact “turn count” for your model.
While your partner holds the roller tube, use your locking pliers to wind the spring. Be extremely careful during this step, as the resistance increases with every turn.
Testing the Operation
After the springs are tensioned and the arms are reattached, it is time for the moment of truth. Slowly unlock the arms and allow the awning to retract under its own power.
Watch the fabric as it rolls onto the tube. It should be smooth, tight, and free of wrinkles. If it looks loose, you may need to add one or two more turns of tension to the springs.
Cycle the awning in and out several times. This helps the fabric “settle” into its natural position and ensures that the polycord is fully seated in the tracks.
Maintenance Tips to Extend Your New Awning’s Life
Now that you know how to change rv awning fabric, you want to make sure this new one lasts as long as possible. The sun is the biggest enemy of vinyl and acrylic materials.
Apply a UV protectant spray once or twice a year. This keeps the vinyl supple and prevents the “cracking” that leads to leaks and tears over time.
Never roll up your awning when it is soaking wet if you can avoid it. If you must roll it up during a rainstorm, make sure to deploy it and let it air dry as soon as the sun comes out to prevent mold growth.
Dealing with Wind and Rain
Off-roaders often face unpredictable weather. If the wind starts gusting over 20 mph, it is time to pull the awning in. Even a brand-new fabric can be ripped from the rail by a strong updraft.
When it rains, always tilt one side of the awning lower than the other. This creates a “water shed” that prevents heavy puddles from forming in the center of the fabric, which can stretch it out permanently.
Check the mounting hardware on the RV wall regularly. Vibrations from washboard roads can loosen the bolts that hold the arms, which can lead to the entire assembly pulling away from the rig.
Common Pitfalls and Troubleshooting
One common mistake is forgetting to lubricate the rail. Without silicone spray, the fabric can snag on the metal, causing a small tear before you even get the awning installed.
Another issue is “spring fatigue.” If your RV is older, the internal springs might have lost their bounce. If you wind them to the recommended count and the awning still sags, it might be time to replace the torsion assemblies entirely.
If the fabric is wrinkling near the RV wall, double-check that the rail is straight. Sometimes the metal rail can get slightly bent or pulled away from the wall, which creates uneven tension across the fabric.
Frequently Asked Questions About Changing RV Awning Fabric
Can I change the fabric by myself?
It is highly discouraged. Because the roller tube is long and heavy, and the springs are under tension, you need at least two people to handle the components safely and align the fabric correctly.
How long does it take to change the fabric?
For a first-timer, expect the process to take about 2 to 3 hours. Once you are familiar with how to change rv awning fabric, a seasoned DIYer can usually finish the job in about 60 to 90 minutes.
Do I need to replace the springs when I replace the fabric?
Not necessarily. Unless the awning was struggling to retract or the springs are visibly rusted or broken, you can usually reuse the existing torsion hardware with the new fabric.
What is the best way to clean the new fabric?
Use a mixture of water and a mild dish soap. Avoid harsh chemicals or bleach, as these can strip the UV coating and weaken the fibers of the material over time.
Should I use a manual or electric replacement fabric?
The fabric itself is often the same, but the way it attaches to the roller tube can differ. Always ensure the replacement kit is compatible with your specific awning brand and model (e.g., Dometic, Carefree, or Lippert).
Summary and Final Thoughts
Replacing your RV awning fabric is a rewarding project that significantly improves your outdoor living space. By following these steps, you ensure a safe installation that will stand up to the elements for years to come.
Remember to prioritize safety when handling the torsion springs and always use a helper for the heavy lifting. Taking your time to align the fabric and set the proper tension will result in a professional-grade finish that you can be proud of.
Now that your rig is looking sharp and staying cool, it is time to hit the road. Stay safe and stay comfortable!
