Well, at least when your considering extra storage for wood or charcoal. I wanted something water proof or at least close to it so I built this box incorporating a ship lap top construction sealed with Gorilla glue at the seams for a weather tight seal. Handles had to applied just to move it, it was beastly heavy. The sides were seasoned pine boards tightly fitted and held with decking screws on to a sturdy frame. The whole box 6'x2'x2.5' sits a few inches above the ground to prevent decay with some 6x6 posts, remnants from the pavillion I built. Nothing fancy, fully functioal and could if needed possibly double as a casket for two. It does need some art work but that'll come later. Just an idea.
