I'm after a wooden (plywood?) grub box for keeping my pans, dry goods, spices and bits in when out camping with the family - sadly when we live right now means I can't get the router table out and make one up. So, does anyone know where I can get one from? Looking for something around 500m x 400mm x 400mm with internal dividers and a drop in deep tray. Not after anything too fancy - just practical and non plastic.
