Choose the chassis, then get an 8 foot flatbed. Put Weatherguard High Side Boxes (or any preferable brand) up on top of the flatbed from the cabguard of the flatbed to the back of the flatbed. I don't remember how long they are, but get 2 going end to end so that basically 2 of the boxes are going to be about 7 feet long, taking up most of the side of the flatbed. Do this on both sides of the truck, so that you have a total of 4 boxes on top of the bed. Then put a narrow tool chest up front behind the cabguard between the high side boxes, probablyg going to be about 4 feet wide or so. Then, put 2 underbody boxes in front of the rear wheels on both sides. That'll give you a total of 7 boxes and about as much storage you can get out of a short chassis. If you went with a 12' flatbed, you could get an additional underbody boxes behind the rear wheels for a total of 9 boxes. When I start working full time, I'm going to get a 1 1/2 ton truck with at least a 10 foot flatbed and use this same setup. This is the best way to get the most versatility and save yourself from getting a huge truck.
