Well the information is out there that most major fleets use F-Superdutys. In our part of the world you can just stand outside the coffee shop and see it. Maybe because of the extreme weather and really poor road conditions up there, the use of F-SDs is more pronounced.
My specific knowledge of the issues with the HD series Cummins powered trucks comes directly form the gen mngr at dealership I recently retired from. He spent 12 years as service mngr at that brand. He was quite aware of the numerous front suspension/steering/electrical issues that occurred regularly at fairly low mileages.
