My cookers sit outside & I use grill cover to protect from the rain & sun.
In the Mississippi sun 2-3 years is all you get from a cover.
Bought a " Classic Accessories " cover as a Amazon lighting deal for $22. To cover my gasser.
To my surprise it's made from a thin polyester material just like tent material
Looks & fits fine, even has a stuff bag for storage , just hoping it will survive the sun!
