I am sort of fond of old F-liners. My Dad worked at the factory in Portland in the 60's. A friend's Dad had a 48 F-liner with so many miles on it that Cummins ran an add on how old the engine was and still running. I don't really want to get into the Mercedes F-liners since they are quasi-foreign now. Even though Paccar is certainly a multi-national company they are primarily US. Of course I could find an oddball like a Pacific or something. If you haven't been to Hanks page then you are in for a treat if you like old trucks.
