I've seen some at the big box home stores that looked like they would work. But I've been using part of the cardboard box the smoker came in for the first month. When it gets too nasty, I'll throw it way and move on to the next thing. Maybe cardboard again. But it would be nice to have something. I roll my smoker to a different location for smoking than storage, so looking for something that would clean up a easy and would be easy to put away when not in use.
