If you are planning using your truck on plowed city streets, I don’t think you need anything but good all season tires and prudent driving technique.
Plowing in a 2wd vehicle??? Maybe in Texas. Not in the North East. The big sanders are 2wd…but they have about 5 tons of weight on the rear wheels.
I understand that weight over the rear wheels increases traction but it also increases overall vehicle weight.
I take it you don’t drive in snow much. And extra 200-400 lbs in the rear will help GREATLY. Been there done that.
Carrying a old piece of carpet (say 4x8) can be put down and it will allow you to move the vehicle onto a better surface (helped me more than ever carrying sandbags)
Good for the 4-8’ you need to travel. Might take a long time getting home away in the middle of a snow storem if you live 5 miles.
