trucks

I'm not sure of what the years are but, from my research on Youtube, the truck Millard Mitchell drove was a Mack AB with chain drive from the 20s or 30s. The ones that Richard Conte and Joseph Peveny drove were Studebaker US6s from the war years.

If you're ever trying to figure out what make and model a vehicle in a movie is, the Internet Movie Cars Database is a fantastic resource: http://www.imcdb.org/
