My guess would be it would be a very small market, and you may have to use a CDl driver. A lot of companies do built auger boxes for trucks, but they are all about half the size you're talking about. I'm not sure but I think the liability would be different to for something that is intended for installment on a high speed truck. Plus all the width limitations. If you can only go 8 1_2' wide, you would have to build it pretty tall to get the capacity you are looking at would'nt youIJ All the corn in this area is fresh corn, but we all use dump boxes behind tractors. One reason is the stalks seem to like fuel lines and air lines on the trucks. Another reason is the inevitable wet spot that once the truck is stuck will be a bear trying to make up all that lost time. If you build one or have one built, let us know where we can view pictures of it please. Maybe on farmphoto or redpowermagazineIJ
