Yeah, the TRX costs as much as a 3500 Limited Longhorn (ask me how I know) but isn't nearly as capable, unless your definition of "capable" is solely how fast it moves in a straight line on any terrain.
You should come hang out with the guys from Dodge Truck Extreme (DTX) if you want to see what these trucks can do with the upper level Carli or Thuren suspension in the desert. Even the Raptor guys get jealous.
