Since it was your GPS giving that reading, it's probably fairly accurate. Since that governed speed isn't a legal mandate, it probably doesn't have to be exact. Also the speed might vary a bit because of drive gear ratios, tire size, and other subtle factors in the truck. It's a shame to some degree that Dodge does something like this.
