The ADCO 34872 Tyvek Designer Series Plus Wind cover will fit 20'1" to 24' toy haulers. This cover has a white triple layered Tyvek top panel and gray triple layered polypropylene sides. It is especially resistant to wind and UV exposure, and can be used in every type of climate. The slip seam strap system tightly holds the cover to the toy hauler, minimizing any impact made by the wind. Air circulation is provided by built-in vents in the side panels, which keep moisture from collecting inside. Comes with storage bag and 4 travel tire guards. When measuring your toy hauler's length, remember to include the bumpers and ladder, but not the hitch. Backed by 3 Year Limited Manufacturer's Warranty. Dimensions: 24.5'L x 120"H x 106"W
