And those KW's aren't that old, I think those are like 2003-2004 but trucks don't really follow the same design as cars. The manufacturers keep the same shit around forever if it works and don't try to be on the cutting edge when the stuff has to be trusted to run a million miles.
It is bullshit that we don't have a newer fleet though. You should see the 20 year old Internationals I drive around. But the new trucks are all brand new Internationals which are complete garbage and somehow more unreliable than the 20 year old trucks.
