Buying Guide: Key Considerations For 18–20 Ft RV Trailer Covers
- Size compatibility: Measure your RV’s length, height, and any protrusions (solar panels, AC units) to ensure a proper fit within the 18–20 ft range.
- Fabric layers: More layers generally improve tear resistance and weather protection. Look for 7–9 layers with reinforced roof areas for heavier snow or wind.
- Wind resistance: Check for integrated windproof straps, bottom tensioners, and buckle systems. Models with multiple anchoring straps perform better in storms.
- UV and waterproof performance: Prefer covers with UV stabilizers and waterproof coatings to prevent sun damage and water penetration over time.
- Included accessories: A complete kit (tire covers, gutter covers, tongue jack cover, repair patches, storage bag) saves setup time and ensures full protection.
- Ventilation: Strategically placed vents prevent moisture buildup inside the cover, reducing mold risk during prolonged storage.
- Installation ease: Some models include step-by-step setup guides or video tutorials; consider ones that minimize handling and folding during installation.
- Maintenance: Look for fabrics that are easy to clean and resist staining from tree sap, bird droppings, and debris common in your storage area.
Frequently Asked Questions
- What size is best for my 18 ft trailer? Best to choose a cover labeled 18–20 ft if your trailer is 18 ft or slightly longer with attachments; ensure height clearance is also accommodated.
- Are 9-layer covers worth the extra cost? Generally yes for harsh climates, as they offer better tear resistance and weather protection, but assess your local weather patterns and storage needs.
- Do these covers need ventilation? Yes, proper ventilation reduces interior humidity and helps prevent mold and mildew during storage or long periods outdoors.
- What maintenance is required after winter? Remove any accumulated snow, dry thoroughly, and inspect straps and seams for wear before the next storage season.
- Can I install a cover myself, or do I need a helper? Most models are designed for DIY setup; however, additional hands can speed installation, especially for larger trailers.
- Will a cover protect against ladder and A/C unit damage? Look for models with reinforced corner patches and dedicated A/C/tower protection, as some corners are more vulnerable to punctures.
