With a half ton pickup, you had best charge an arm and a leg. Ploughing/plowing snow is brutal on all the elements of a pickup, and Half-tons won't last. If you have a line on a grit spreader (assuming you call it grit since you spell it plough) for the bed, you might want to market yourself to shopping centers, office parks, et cetera with both ploughing and de-icing, and hope for minimal accumulations.
