Greetings guys, I'm new to the site and to GM in general. I just picked up this clean 85 Bonus Cab dually 3500, and though it has a few problems which I'll post about in a different thread, there's one thing I'm a little confused about. What exactly is a "Bonus Cab?" I've read that it's basically a Crew Cab with the back seat deleted and converted into lockable storage, however this truck has a bench seat in the back. It's hard to find much of anything on trucks with these "Bonus Cab" badges, although I have heard they were popular with customization businesses. I've got no paperwork to go on except a title. Any idea how many of these Bonus Cabs were made? Where should I go to find information like that?
