I've got another one for you on Dodge Trucks of the 1960's and 1970's:

In addition, I'm going to throw you all some footnotes:
1)Dodge Medium-Duty D-Series Trucks existed until 1978.
2)Four-Wheel-Drive Dodge D-Series Trucks were W-Series Trucks.
3)Medium-Duty D-Series Trucks for school buses were called S-Series Trucks.
4)Besides "Power Wagons" being added as a special package, there were also models created specifically for tow trucks and snow plows. The snow plow package was originally called "Sno-Fiter," then "Sno-Commander."
