Freightliner Frame manufacturer seems to have evolved and put the battery in its given location and probably builds some of the boxes on to the chassis for even the house batteries is my guess. But either Winni or Freightliner or both are getting a little better at addressing the design and build quality of their products and that is a good thing. Over all though the industry was very much like snake oil sales as in Caveatemptor its improving but rather slowly. Unified warranty process is a must and necessary single point of contact process, can you imagine having to deal with the airbag manufacturer individually for your car or truck? Super majority of rigs are not really driven that much in a year and so the mechanical warranties should actually be longer than automobile warranties given the nature of HP and torque and driving characteristics, adjusting the maintenance schedule as well.Remember how long we waited for the industry to move from wood framing walls n body to metal! too slow to embrace new improved product design and innovations. Fuel cells when?
