When plowing with a dually, it is crucial to have a plow that is wide enough to clear a path for the rear wheels to follow. If the plow is too narrow, the outside wheels will run over snow causing ice. Also when using a plow that is too narrow, the truck risks scraping snowbanks, trees, or other obstacles when plowing into a turn. A good rule of thumb is to never use any plow smaller than an 8-1/2' straight blade or a 9-1/2' V Plow. This 2000 Ford F-350 will be pushing a used 9-1/2' Western UltraMount MVP+ around New Jersey.
