Jim,
I will have to disagree with everyone else on some points, and help to support some of your ideas. I drive a 1986 chevy 1-ton dually 4-wheel drive. This truck will go anywhere, I have never had it stuck, not even pulling a trailer through 12 inches of wet snow in 2-wheel drive. Mine is, however, a cab and chassis truck, not an actual dually pickup. It has a narrower rear end than a dually. The fron tire splits the duals in the rear. The other people were correct in saying that the more surface area in contact with the ground, the less the weight per square inch of contacting surface. The reason for tracks on tractors is to reduce compaction, which is a direct result of the less weight per square inch of contacting surface. If you have ever driven or ever get to drive a tracked tractor in soft soil such as a sandy soil, or in mud, you will wish you had the tires back, since it will bury itself faster than you can blink because there is not enough pressure to "pack" the soil beneath the track to make it stable enough to prevent overcoming the static friction. If you are going to do much hauling, or trailer pulling, get the dually, otherwise there is not much benefit from it except having to pay $250 more when buyng tires.
