I'm shopping for a new snow plow to put on my Chevy Silverado 1/2 ton. All the applications I have looked into call for a light duty plow. I need a commercial duty. I was told the only reason they suggest a light duty is because I could have a truck full of people in the crew cab which would put it over the weight limit. Anyone else out there have a commercial plow on a 1/2 ton truck? Thank you.
