There's not much in here that screams "work truck," is there? The heavy-duty GM pickups are just as well-appointed inside as their light-duty brothers. We like that GM's trucks are fully instrumented and offer high-end options like navigation systems. We don't like having to hunt around on the instrument panel for things like 4WD engagement. In one truck we drove, the heater and A/C control was blocked by the transmission lever when it was in Drive. Ergonomically, these trucks still need some help.
