The ADCO 34871 Tyvek Designer Series Plus Wind cover will fit toy haulers up to 20'. This cover has a white Tyvek top panel and gray polypropylene sides. Both the top and side panels feature triple-layer protection. This cover is especially resistant to wind and UV exposure and works in every type of climate. The slip seam strap system tightly holds the cover to the toy hauler, reducing the impact made by the wind. Circulation is provided by the side panel's built-in vents, which keep moisture from collecting inside. Storage bag and 4 travel tire guards included. When measuring your toy hauler's length, do not include the hitch, but still include the bumpers and ladder. Comes with 3 Year Limited Manufacturer's Warranty. Dimensions: 20.5'L x 120"H x 106"W
