Ice is ice for sure........ So is anything that won't allow much traction. That's why some inexperienced clowns get stuck because they think 4wd can go anywhere. That's when they discover that they can sit there stuck and spin all four wheels at once instead of just two. I don't use the 4wd on my Tacoma all that much but when I do it's worth its weight in gold. Have navigated some deep unplowed snow with both my 97 and 09 Tacomas with no problem in depths that I would never even think of with my old 2wd trucks no matter how much weight I had in the bed.
