Yep.
Some more info: A bunch of the AMT kits were upgraded with CB radios & other accoutrements, so some of them changed years. For example, the original GMC Astro/Chevy Titan kits represented '69-'73 trucks, with: cab-mounted mirrors, square fuel tanks, slanted grab handles, low-mounted blinkers, & battery box steps. The upgraded kits resemble '74-'79 trucks, with: door-mounted mirrors, optional round fuel tanks, S-shaped grab handles that extend over the doors, high-mounted blinkers, & metal tube steps. They are also available with CB radios & roof-mounted dragfoilers. The current GMC Astro kit is the same, but curiously, there's no Chevy Titan to accompany it.
Also, didn't AMT release a BJ & the Bear Kenworth K-100 kit as well?
One other note: AMT was planning a Ford C-Series garbage truck, and though the box design was completed, the truck was unreleased.
