When we went on our month driving trip I had no idea DH brought a tool box. It came in handy because we ate outside at our lodge and the big guy could hear my voice but not see me. He was pushing on the accordion type material that is on either side of a window air conditioner. He almost sent the whole thing flying 2 stories. DH looked up and noticed. We brought him down with us and after dinner he fixed it with his tools. I was surprised he brought them.
