There are pros and cons. Snow plows beat on a the vehicle - which is why plows are the last thing a truck does before you quit using it. Highway departments will use a dump truck mounted plow because the frame of the dump truck can take the beating (that they can put salt on the dump truck is a very useful side effect). Tractors are designed to pull plows through dirt which also beats on them, and so tractors can stand up to snow plows better than a truck. However tractors are slower and so cannot work for on road work. PTO and hydraulics are useful as well.
Not OP, but here in park city UT, we average ~21 feet of snow a season and got an epic 51 feet last season!
I normally see dump salting trucks with plows that plow/salt the roads during snow falls and then we have cat bulldozers that later come pick up the snow and move it into dump trucks to be hauled away.
