 I don't know how they did that. The only thing I can think of is with all the new trucks, they wanted everything to be more sleeker, and the only way to do it was get the exhaust out of the equation. I don't know why they couldn't have built bearings around the exhausts, because I have seen that before in the past. I don't know. I do agree with him that companies don't put enough emphasis on drivers, and they need to for driver safety.
