I was thinking a GMC Astro slab cab with the double breasted yamaha (318 detroit).One of the nicest looking cab-overs ever
The GMC Astro was a twin sister to the Titan 90. Had a wrap around dash that curved around and down the center on the cab. So some of the controls and gauges were beside me and in easy reach with right hand. Lots of aluminum, frame and cab all aluminum! Tractor weighed in at 15K and aluminum 8500 gal trailer weighed 10K, giving a 25K tare weight. 8500 x 6.1 + 25,000 =76,850, so there was some room to have some diesel in some of the compartments(5). Only problem was the axle spacing was short of Washington State bridge laws. I hauled out of a Texaco Terminal in Port Angeles, Wa. My uncle started the company in 1933, then my father and the book keeper bought it. Dad drove a single screw Crackerbox GMC in the end with 318. I worked there as a kid, and my dad sold his 51% to the book keeper in early 1976, that August I went to work for him and drove the tanker for 3 years. It is harder work than some might believe. We carried a lot on case goods in two driver side compartments. These compartments would also hold 55 gal drums of oil. Dump hoses were 4" and heavy and stiff! Between driving truck and riding a dirt bike on week-ends I was in pretty good shape.
The Chevrolet Titan 90 (and similar GMC Astro 95) were heavy-duty Class 8 cabover trucks made by General Motors between 1968 and 1988. When introduced, they replaced the GMC F-Series "Crackerbox" & featured an all-aluminum tilt-cab. Diesel engine choices included Caterpillar, Cummins and Detroit Diesel powerplants.
In 1980, both trucks were redesigned with a bigger grille, which was optional on the SS or Special Series Titan models and Astro 95 in 1978-79.
1980 was the last year for Chevrolet Semi Trucks or Big Rigs (Class 8 Heavy Duty Trucks).
The Titan 90 was introduced in 1969. In 1980 (the last year for The Titan), it was just Titan.
The GMC Astro 95 was introduced in 1968 as a 1969 model and made until 1987. In 1980, the name was just GMC Astro.
The GMC version was more common than the Chevrolet version.
The GMC Astro single-axle City Tractor with two 28 foot trailers was used in the film Beverly Hills Cop in the cigarette chase scene
