Not as cool as Code54's steel box but thought I'd give it s try. All I have at home is a circular saw and a drill. Total cost was around 110. I could have cut it down to 80 or so but I decided to use 2 quarts of liner to make sure it was nice and thick and go with aluminum hinges. Box is made out of 3/4 inch plywood, aluminum hinges, tailgate is cedar just b/c I wanted a solid piece of wood and I had cedar laying around, then lined it all with herculiner.
