Put studs on the rear of the truck and at least 500 lbs (directly) over the rear axel. When I had my rear wheel S-10 that thing did real well. Slow and easy you go! If you get in deep snow...chains! We put chains on a car stuck in two feet of snow and drove it right out on quite an upgrade! A friend of mine has one heck of a driveway and puts studs front and rear on two wheel drives!
