You literally just described a pickup truck, the highest selling car/truck in America. They're used as busses, all kinds of repair trucks, they can go in railroad tracks, etc. Point is, a truck that plows snow and a truck that is a trash truck are mostly the same thing. You take a diesel cab truck chassis, and add either a plow or a trash compactor to it. It's also easy to add both. It's not as if the trash trucks in cities that don't use them to plow are some highly specialized thing. They're the same trucks as new york has, just no plow. A plow bolts on.
