I just wanted to post something to break the tension. I grew up on a 23 and 25 series Freightliner. This was a Roadway version. CF had many set back axles like these as well. Iam not sure if the Big R s had a Detroit or not but at PIE we had Cats with a 9 speed. I dont think ABF had a long nose Freightliner back then. Anyway just a thought drivers of 6 ft Francis antennas and radio boxes.
