There is a whole book bumper minimum width, height, angle, it can only be so low, so high, the basic problem is that bumper will not allow proper contact with another vehicle, will cause serious injuries to others that vehicle comes in contact with. Its not so much if its legal or not its the damage that truck will cause to other vehicles, such as causing the other vehicle to submerge under it. This is the dreams attorneys look for that will cause injuries to be able to sue, the builder of the bumper, the owner of the truck and so forth. I am just saying, I like the bumper, can not afford the following lawsuit. Its not so much the person in the truck cares, its the person that gets hit that will get the 5 million settlement because no matter who is at fault in the accident, those injuries were avoidable with the stock bumper and therefore the injured party gets a big fat check..
