Last weekend we got our last snow of the season (I hope) and I noticed several pickups on the interstate, with plows mounted. The one had a v-shaped plow so aside from potential cooling issues, that seemed OK, but there were several I saw with straight plows, canted to one side, while driving 75 MPH or more. What would that do aerodynamically? Would the truck want to pull to one side or the other? I would imagine the additional weight might make it handle a little funny anyway, but the off-center plow surely wouldn't help anything.
