This fully removable tool box has everything... a generator, compressor, and welder... all in one. The controls are all behind the driver side front cabinet secure and out of the weather. Also, you don't have to climb up into the bed to connect hoses, power, or built in jumper cables. This unit is made for work anywhere. If you're a framer, you can leave this unit on site by off loading via the built in jack recepticles, with all your tools, nailers, and supplies securely in the 1000 pound capacity drawer. Everything you need on site, then you can take the truck to the lake do some fishing... without carrying all your tools with you everywhere you go. Just one of the many jobs this tool box was made to handle.
