I am looking to buy a new or slighlty used Ford F-450 with a dump bed. This will be the first larger vehicle I will be buying, we have been using 3/4 ton trucks. A lot of the F-450's that I have been finding are 4x2, and the few 4x4's I find are signifigantly more $$$. I live in Maryland and have some plowing contracts, would a 4x2 be okay to plow with. I know its a heavy truck, but is heavy enough for plowing with only 2 wheel drive? Does anybody out there do this?
