I'll be buying my first plow truck tomorrow. It's a 2011 RAM 3500 dually with a Boss V plow and metal dump box. My primary use is for our two mile dirt road between our camp and the nearest plowed road but might also take on side jobs. How much weight should I need to start with when finding a good fit for rear traction. It's a four wheel drive with brand new tires being installed today. I saw a post about ensure tire pressure is down around 40-45lbs. Any other tips or tricks for a noobie would be appreciated.
