Here are 2 pics of the last fab project I did. I bear hunt during the summer and ealy fall months and I couldn't find a dog box that was big enough(I have 11 fullsize hounds and 6 pups at the moment) or a design I liked. So out came the TIG torch, lol. Its all diamond plate aluminum with every seam TIG welded. Just for a general size, it takes up all the room of a short box on a toyota and complete covers the rear window as far as height. I have a seperate flatbed that I put on the truck in my avatar during season for this box. I know it doesn't have much to do with "off-roading" per say, but you should see the stuff we go through here to get to our dogs, lol.
