Winter's coming and I wanted no issues with snow, ice and temp changes raining down on my investment. Made with poplar, a hard wood that takes paint well and I just happened to have a couple thousand board feet of it, so it was an easy decision. Cedar shingled roof and it has removable shelves if you wish to use it for storage. It will hold everything the KK came with and all my other grates and things that my other Kamados have and it wheels around quite easily. I had no need for a door but, I suppose you could hang a rod for a curtain or I was thinking of a small detachable shed roof you could hang on with brackets. So there it is, nothing fancy but, an alternative to a cover and another way to protect your KK.
