There were a few years in the late '70s where you could order two tanks, and in some cases they came with the in-cab and under bed tank. I've also seen the two under bed tanks in those years as well, so I'm not sure why the two options existed after the normal in-cab tanks were phased out...
Not many 1/2 tons came with 440, I have one myself (76 W100 shortbox AdventurerSport 4x4 with auto and fact. A/C)
