The Mack truck
Post 28- is the same cab as most of those above, with a more modern nose.
They did change the cab IIRC late 90's or early 00's and IIRC are still using it.
No more offsets, either.
There is a Mack/Volvo service center about 3 miles from my house.
I see small fleets of cab and chassis, tractors, cement mixers and dump trucks there all the time, most brand spankin' new.
