Snow driving coming soon. How much weight needed?

[BonsaiGT]

I own a 1990 Toyota Pickup Deluxe (2WD) that will most likely see Ohio snow this winter. Having not driven a rear-wheel drive vehicle in snow in several years, I want to make sure I've weighted the bed properly before snow falls. I know the truck weighs somewhere in the vicinity of 2,500 pounds, but since I don't know how much weight is on each axle, I'm not sure how much weight I need to put in the bed for decent handling. Anyone?

im drivin in the snow already with a short bed single cab pickup with 33 12.50 tires (bald) i wouldnt be able to get up very many icy hills without 4 dig... so youll need like 200 lbs prolly right over the wheel wells
