• 【UPGRADED FABRIC】300D oxford for top and 150D oxford for sides. Maximum tension up to 400 lbs (300D) and 180 lbs (150D). 100% waterproof, up to 2,000 mm water-resistant due to the PU coating. Much better than 7 layers non-woven fabric (maximum tension: 70 lbs, water-resistent: 500 mm). Our oxford fabric is also added with anti-uv component to reduce aging and degradation caused by sunlight. It lasts at least twice as long as non-woven covers. 【WINDPROOF】 The position of the middle tension panels on the side effectively increases the stress area. 2 additional webbing straps are included to fix the cover more tightly to against blowing away and tearing by heavy wind. Meanwhile, the 10 air vents on the top can effectively reduce wind stress and quickly let moist escape. 【ACCESSIBILITY DESIGN】 Totally 3 rollable zipper panels on the passager side allow accessing to the trailer anytime, easy to view and check interior situation. 4 reflective strips in front and rear for safety avoid collision during night. 【FULL CONTENT】 Class A RV Cover ×1, Tire Cover ×4, Webbing Strap ×2, Gutter Spout Cover ×6, Adhesive Repair Patch ×1, Storage Bag ×1.
