I've got one as well made out of an '83 3/4 ton. Very useful for hauling rock, wood, sand, OSB, sheetrock.....anything. I've had people give me a hard time about it being ugly, but it gets a lot of use and borrowed a lot at well. I'm going to make another out of my '86 2wd as well and sell it.
In Wisconsin, if it only has one axle, you don't need to register it.
Also, I cut mine right behind the front cab mounts, notched the frame right in front of the box, bent them inward, and bought one of these from Grainger. http://www.grainger.com/Grainger/wwg/productIndex.shtml
And then went back and welding everything up good and solid.

make sure to cut it right behind the front doors leaving one set so you can enter from the sides on the front.
I coulda swore there was a topper on the bed though.
