I heard through the industry that there was a few lawsuits that happened in the early 2000s that weekend truck users would overload utility trailers and the front end of the truck was raised so the visibility wasn’t as good, so the OE’s added rake to the rear end so that 3 percent of the time you have a trailer on it is level. The accidents where probably due to overloading but let lawyers get ahold of a case. Manufactures have to protect themselves by doing everything they can to prove that they did so when the lawyers take them to court the can say they tried. That is the legend in the Transportation Business.
