I am thinking about getting a used Ford F250 or F350. I am not sure if I should buy those truck with plow on it already or not. If an used truck have a plow on it, it mean that it had been worn, but sell for less money. A truck that never plowed should last longer. What do you suggest me to buy, an used F250 & F350 truck with used plow on it or a truck without plow on it and buy a new plow for it?
