Don't use it for snow, but when it's raining. I have a well so use salt bags.
You might want to think twice about putting any unsecured weight in your vehicle. A few years ago a coworker of mine used cement blocks, was in an accident and one of the blocks flew through the back glass clocking him in the head. It knocked him out and left a nice gash in his head.
I want to permanently weigh down the rear end of our 2013 GMC for better traction. I see where everyone want to throw something in the bed and thinks that's ok, well what happens if you do wreck and get slammed in the back of the head with cinder blocks, bags of sand, or concrete? what if it fly's out and hits someone else? someone please give me a solution that's safe and professional
