Design and Build Quality
The Classic Accessories PolyPro 3 Deluxe cover has been carefully designed to balance toughness and breathability. It features a triple-layer polypropylene top that provides substantial protection from UV rays, rain, snow, and dirt. This thicker top panel shields the most exposed areas of your trailer—the roof and upper sidewalls—from sun bleaching, cracking, and moisture damage.
The single-ply polypropylene side panels are lightweight and breathable, helping reduce condensation build-up underneath the cover. This improves airflow while still offering protection from dirt, bird droppings, and tree sap.
All corners of the cover are reinforced with double-stitched seams, which adds strength where it’s most needed. The adjustable tension panels in the front and rear make it easy to tighten the cover to fit your trailer’s contours, minimizing fabric flapping or sagging.
The included ladder cap is a thoughtful addition—it helps reduce friction between sharp ladder edges and the fabric, preventing premature wear. The cover’s overall construction feels durable, weather-ready, and carefully engineered.

Weather Resistance and Performance
The PolyPro 3 Deluxe excels in all-season protection. It is designed to handle rain, snow, wind, and UV exposure, making it ideal for RV owners who store their trailers outdoors year-round.
☀️ UV Protection
The triple-ply top offers substantial UV-blocking performance. It prevents your roof and upper walls from fading or cracking due to prolonged sun exposure, especially useful in high-sun climates.
🌧️ Water Resistance
The cover’s water-repellent top layer resists heavy rainfall, keeping the trailer dry while the breathable sides allow moisture and trapped humidity to escape. This combination helps avoid mold, mildew, and water-related damage inside and out.
❄️ Snow and Cold Weather
The PolyPro 3 can withstand moderate snow loads, provided snow is not allowed to accumulate excessively. Its sturdy design resists tearing and maintains integrity in freezing temperatures.
💨 Wind
With its adjustable straps, tension panels, and integrated vents, this cover performs well in windy conditions. The vents relieve air pressure by allowing circulation, reducing strain on seams and preventing the cover from billowing or tearing.
Installation and User Experience
Despite its large size, installing the PolyPro 3 Deluxe cover is straightforward. The process typically takes two people and around 20–30 minutes the first time. Subsequent installations can be quicker once you’re familiar with the steps.
Here’s what makes setup easier:
- Toss bag included for passing straps under the RV
- Elasticized corners help the cover hug the trailer’s body
- Straps and buckles cinch down the cover for a snug, secure fit
- Zippered access panels allow you to open doors or check compartments without removing the entire cover
When not in use, the cover folds compactly into the included stuff sack for storage. The bag itself is large enough to accommodate the cover easily without excessive wrestling.
