Tools and Equipment Needed for Installation
Before beginning the installation or replacement process, it is essential to gather the necessary tools. According to user experiences and technical guides, the following equipment is typically required:
- Two people: The installation is a two-person job due to the size and tension involved.
- Two sturdy ladders: These are needed to access the height of the topper installation.
- Locking oil filter wrench: This tool is used to manage the tension in the roller mechanism during fabric replacement.
- Lubricant (silicone-based or Boeshield T-9): Used to maintain smooth operation of moving parts.
- Drill with a 1/4 inch bit: For any minor modifications or adjustments.
- Metal file: For smoothing edges or surfaces as needed.
- Phillips screwdriver and Allen wrench: For removing and reattaching screws and components.
It is worth noting that most of these tools are likely already in an RV owner's toolkit. The only item that may need to be purchased or borrowed is the locking oil filter wrench, which is essential for managing the tension in the spring-loaded roller during fabric replacement.
Step-by-Step Installation and Replacement Process
Replacing a Dometic SlideTopper involves several steps, each of which must be performed carefully to ensure proper alignment and tension. Below is a detailed breakdown of the process, based on verified technical guides and user reports.
Step 1: Preparation and Removal of the Old Cover
- Remove the Slide Cover: Start by removing the cover from the slide. This typically involves loosening or removing screws from both ends of the slide cover. The top screw can often be loosened slightly, while the bottom screw must be completely removed.
- Access the Roller Mechanism: Once the cover is removed, locate the spring-tensioned roller at the center of the topper assembly. This mechanism is responsible for retracting and extending the fabric.
- Unroll the Fabric: Carefully unroll the fabric by grasping the roller and pulling the fabric out. There will be some tension due to the spring mechanism, but it should not be excessive.
- Clamp the Roller Tension: To prevent the spring from releasing tension during the replacement process, use the locking oil filter wrench to clamp the roller in place. This is typically done at the end of the roller closest to the middle of the RV. Clamping the tension allows the fabric to be removed without the risk of the spring mechanism becoming uncontrolled.
Step 2: Removing the Old Fabric and Preparing for the New
- Widen the Channel: Use a metal file or other appropriate tool to slightly widen the channel on the roller. This makes it easier to remove the old fabric without damaging the roller.
- Remove the Old Fabric: With the tension clamped in place, carefully remove the old fabric from the roller. This is typically done by pulling the fabric out from one end of the roller.
- Prepare the New Fabric: Before inserting the new fabric, ensure it is cut or measured to the correct dimensions. Users are advised to subtract 1.5 inches from the measurement for back slides and 3–4 inches for front slides to allow for proper tension and alignment.
Step 3: Installing the New Fabric
- Insert the New Fabric: With the tension still clamped, insert the new fabric into the roller. Ensure that it is fed evenly and without twists.
- Secure the Fabric in Place: Once the fabric is fully inserted, hold the roller firmly with your hands and slowly release the tension by removing the locking wrench. The spring mechanism will begin to roll the fabric onto the roller, tightening it in place.
- Check Alignment and Operation: Before completing the installation, test the alignment and operation of the topper by extending and retracting the slide. This ensures that the fabric is properly aligned and that the mechanism functions smoothly.
Step 4: Reassembling the Slide Cover
- Reattach the Slide Cover: Once the fabric is properly installed and tensioned, reattach the slide cover by following the reverse of the steps used during removal. Ensure that all screws are tightened securely.
- Reattach the Screws Holding the Fabric in Place: The fabric is typically secured to the roof channel with two small screws. These should be reattached to ensure that the fabric remains in place during operation.
- Lubricate Moving Parts: Apply lubricant (silicone-based or Boeshield T-9) to any moving parts, such as the roller mechanism or hinges. This helps to ensure smooth operation and reduce wear over time.
Tips and Best Practices for Successful Installation
Several tips and tricks can help ensure a smooth and successful installation process:
- Retain Spring Tension: One of the most important aspects of the installation is retaining the spring tension in the roller. By clamping the tension in place before removing the old fabric, you avoid the risk of the spring becoming uncontrolled or damaged.
- Work in a Controlled Environment: It is best to perform the installation in a dry, clean environment to avoid dirt or debris getting into the mechanism.
- Use Two People: As mentioned earlier, this is a two-person job. Having a second person helps with holding the fabric in place, managing the tension, and ensuring that the installation is done efficiently.
- Test the Mechanism After Installation: Before finalizing the installation, test the slide to ensure that the topper extends and retracts smoothly and that the fabric remains taut and properly aligned.
Common Issues and Troubleshooting
Despite following the correct procedures, some users may encounter issues during or after installation. A few common problems include:
- Loose or Sagging Fabric: If the fabric appears loose after installation, it may indicate that the spring tension was not properly managed. In such cases, the installation process should be repeated, paying close attention to the tensioning steps.
- Misalignment: If the fabric does not align properly with the slide or the roof channel, it may be due to incorrect measurements or improper feeding of the fabric into the roller. Rechecking the measurements and ensuring that the fabric is fed evenly can help resolve this issue.
- Stiff Mechanism: If the roller or hinge mechanism feels stiff or unresponsive, applying lubricant to the moving parts can improve performance. If the problem persists, the mechanism may require more extensive inspection or replacement.
User Experiences and Feedback
Several users have shared their experiences with Dometic SlideTopper replacement. One user, after replacing their toppers with a new set of Carefree SOK III covers, reported significant improvements in durability and performance. The new fabric was described as “much thicker and sturdier” than the previous material, and the anti-billow device worked effectively in preventing wind-related damage.
Another user shared a detailed account of the installation process and highlighted the importance of using a locking oil filter wrench to manage the spring tension. According to the user, retaining the spring tension during the fabric replacement process saved a considerable amount of time and effort compared to releasing the tension and then attempting to reapply it later.
Conclusion
Replacing a Dometic SlideTopper is a manageable task for DIY enthusiasts and experienced RV owners. With the right tools, careful planning, and attention to detail, the process can be completed efficiently and effectively. The key steps involve preparing the installation area, removing the old fabric, installing the new material, and ensuring proper tension and alignment.
