Keep your travel trailer protected season after season with the Classic Accessories PolyPRO3 Model 5 cover. Engineered for trailers from 27 to 30 feet with a maximum height of 118 inches, this cover combines a breathable, water-repellent fabric system with a secure 8-point rope tie-down and integrated air venting -- so your rig stays clean, dry, and ready to roll when storage season ends.
The PolyPRO3 is Classic Accessories' mid-tier travel trailer cover line, balancing durability and breathability. The top panel uses a three-layer PolyPRO 3 fabric -- a heavier, more weather-resistant laminate -- while the sides use quick-drying PolyPRO 1 material that allows moisture vapor to escape. This combination prevents the trapped condensation that can lead to mildew, delamination, and interior damage during long storage periods.
Adjustable front and rear tension panels let you dial in fit across different trailer body shapes, while elasticized hem corners keep the cover snug at the roofline and sides. The result looks and behaves more like a fitted cover than a generic tarp, without the installation headache of hard-shell enclosures.
Vents on the cover reduce wind lofting and allow interior moisture to escape, preventing mildew and condensation buildup under the cover.
Four integrated rope attachment points on each side (8 total) let you secure the cover firmly against wind without damaging the trailer's exterior.
Front and rear tension panels plus elasticized hem corners provide a custom-tailored fit across a range of trailer body profiles within the 27-30 ft size class.
The included toss bag lets you throw the cover over the trailer and feed it underneath without crawling on the ground -- a real time-saver for solo installation.
Classic Accessories uses a dual-fabric approach on the PolyPRO3 series. The roof panel -- the area taking the most punishment from UV rays, rain, and snow load -- uses the heavier three-ply PolyPRO 3 laminate. The sidewall panels use the lighter, faster-drying PolyPRO 1 material. Both fabrics are treated to repel water and resist UV degradation.
The PolyPRO3 is intentionally breathable rather than fully waterproof. A 100% waterproof cover traps humidity and accelerates condensation damage. The PolyPRO3's venting and quick-dry fabric let moisture vapor escape while still repelling rain and blocking UV -- the correct approach for long-term RV storage in most climates.
Strategically placed zippered access panels let you reach hookups, doors, or battery compartments without removing the entire cover. This is particularly useful for trickle-charger connections or quick checks during the off-season without the hassle of a full uncover-and-recover cycle.
Model 5 is sized for travel trailers 27 ft to 30 ft in length with a maximum height of 118 inches (approximately 9 ft 10 in). Measure your trailer's length bumper-to-bumper and height from the ground to the tallest fixed point (typically an AC shroud or vent cover) before ordering. If your trailer exceeds 118 inches in height, a taller-profile cover will be required.
Classic Accessories offers the PolyPRO3 in multiple size models to fit different trailer lengths. Model 5 (01-0374) covers 27-30 ft trailers. If your trailer is shorter or longer, verify the correct model number before ordering to ensure the cover's adjustability range will provide a proper fit.
