I LOVE the design of this cook box. The bottom of the box slides completely out for easy cleaning which is a great feature. I didn't realize it was a 2 piece lower box. I don't think the drip pan ever got dirty. When I picked it up yesterday the pan had aluminum foil wrapped around it. I also love the fact that all the wood sections lift right off and can go in the garage, out of the weather, until you're ready to use the grill...another great design
