The SIG boxes are here http://www.sigmfg.com/IndexCatalog0903.html

Our box that always comes out of the truck is a discontinued Goldberg Mini Tote. No plans available but the design is simple enough a person could make something similar by looking at the picture. It holds fuel, pump, starter, battery, glow driver and a small screwdriver.

We have a plastic tool box, about 18 inches long, for props. A battery and field charger are in this box. It only comes out if we break a prop or need the charger.

We have huge Plano tackle box that has lots of compartments and drawers for tools and parts. It is very heavy so We always hope it stays in the truck.
