The ADCO 34873 Tyvek Designer Series Plus Wind cover will fit 24'1" to 28' toy haulers. This white and gray cover has a triple-layered Tyvek top panel and triple layered polypropylene sides. It is designed resistant to wind and UV exposure and can be used in any type of climate. The slip seam strap system tightly holds the cover to the toy hauler, reducing any impact made by the wind. Air circulation is supplied by built-in vents in the side panels, to keep moisture from collecting inside.
