This is a pic of a !973 White Road Boss, this is what we were driving when I started at Roadway in 1975. They were powered by a 318 V8 Detroit with a 10 speed Roadranger. Manual steering and some of Roadways first equipment to have radial tires. They had them turning about 2350 RPM and had a road speed of about 73 MPH. These old Autocar cabs are my favorite cab of all time. Unlike the poorly designed cabs of today they had big enough glass for visibility without the fishbowl feel of the cabs today. Seats were Bostrom hydraulic with seperate adjustments for height and firmness, much better than an air ride seat in my opinion. They had a defroster that was so powerful it would melt the ice on the hood. Never had ice buildup on the windshield....ever.
