Bunk size is also a huge factor comparing the Kenworth to this unit. Much taller than this Peterbilt, but this unit is equipped with full lockers, a 15 L ISX Cummins and an 18 speed automatic, opposed to the Kenworth's 13 L Paccar engine and 12 speed automatic.
I haven't driven a 579 yet. I eventually want to buy my own truck but I dont know if I should get a Peterbilt 579 or a Freightliner Cascadia. Im definitely getting a manual transmission as automatic is horrible.
Are you sure that transmission isn't an 18 speed auto shift transmission. Eaton numbers it's gears as LL (Low Low) L (Low) then 1-16 for eighteen speed transmissions and the same save for 1-11 for thirteen speed transmissions. I'm curious what is the best fuel economy you are getting with that drivetrain setup.
You'd be correct Hudson! The fuel mileage on this truck isn't a great example because it spends most of its time hauling 80,000lb loads, 120,000lbs gross in the hills of northern Ontario, However it's averaged a little over 6MPG doing this.
It all depends what concept of truck you get, Cascadias, Western Star 4700's, Kenworth T680, Mack Granite, International Prostar's all have much wider cabin's then this model.
Trucker_Trav6132 But no American truck has such a big cabin and are not as tall as European trucks I saw American trucks in Croatia are not that big trucks And are not strong as a European of 730 or 750 factory hp
Our trucks are 13 feet 6 inches tall, and the cabin is a couple inches of that height, however no american trucks come factory with a HP rating of 700, the biggest factory HP is 600 I believe.
