I bought an '08 regular-cab Taco last March and the snow was pretty much gone by that time, although I recall one morning where it had snowed an inch or so and I noticed a bit of squirelliness in the rear end. I had an '89 Toyota pickup which I sold in '97, and recall it being a bit tricky at times on slick roads.
Most people with pickups around here, where we'll often have snowpacked roads from Thanksgiving until Easter, put varying amounts of "tube sand" in the bed. I went and picked up four bags of it, 60# per bag, and am thinking I'll put those in the bed immediately over the rear axle when the roads get slick. Any thoughts? What amount of extra weight, assuming an otherwise empty bed, would you think might give best traction and handling in your Taco on snowpacked or icy roads?
